IT Disaster Recovery - A Finance Perspective

Many financial directors think of IT Disaster Recovery as something that never really happens to them and even if it did the business would be able to get back to business as usual inside a day or so. Assets are safeguarded , backups taken (usually), and unless you are forced to, having a plan and some good intentions are equally as good as having DR equipment sitting around doing nothing utilising the earth's resources at great expense. This philosophy is green too!!!

There are of course tangible business reasons for disaster recovery, namely compliance with customer and supplier requirements , reductions in Insurance premiums (if you can get any) and badges of accreditation such as ISO27001 and BS25999 or industry regulations. Still it all costs money so doing this as slowly as possible using the least amount of resource and cash (any old equipment will do won't it?) means we can achieve almost what we want but without wasting money. No impact on results, job done!

As a former CFO for a small technology sector PLC in the UK I admit that these are some of the thoughts I have had when it comes to disaster recovery and I am not alone (a BT Global Services survey in May 2008 found that 73% of organisations rely on the ad-hoc dedication of their staff rather than their business continuity plans to get them through a disaster). The thing is that unless I wanted to spend more than double my IT budget by having an all singing all dancing duplicate site I may as well be resigned to the fact that if we have a freak tornado come down the Thames Valley or have a jumbo jet fall out of the sky then so be it. I'll take my chances with the insurance company.

Up until a couple of years ago I would still have sympathy with this rather jaded approach to IT DR. If I wanted anything good that would work I could not afford it and if I made compromises on budget and do with less, in all probability it would not work (as we could not afford to test it regularly and risk impacting the business) so why spend anything except on writing the Business Continuity plan wrapped around some best intentions and still be able to tick the compliance box.

The world has however moved on and when we have a 'Disaster' in IT everybody knows about it as we have become more and more dependent on it always being there. Most of our systems are now considered critical (Up from 36% in 2007 to 56% in 2008 in a Symantec survey Aug'08). However IT Disasters which effect the end user are not confined to being a flood or an earthquake, these are quite rare. Most IT Disasters are caused by IT itself, namely hardware failure, software glitches, infrastructure issues and human error. Becoming more frequent with no lesser effect on our businesses in the same Symantec survey above it discovered that one third of companies had executed their DR plan, at least in part, during the past year.

My ignorance has been however how much of a risk to the business an IT disaster can be. Sure it would have a massive impact for a short while but that is based on my assurances by my IT team that all would be well. Perhaps I may have asked the wrong question? The facts however may be a little different. For example if we lost a number of our computer systems by way of a fire, theft, power surge etc . In our plan we would need to source some new kit via the supplier names listed. There is every likelihood that most of this would be delivered next day (unless its Dell) but more probably the day after (because the delivery address has changed), however key peripherals such as Cisco firewalls and routers or tape drives are often not standing on the shelves and in some cases depending on how far up the enterprise IT food chain you are could have a 4 -8 week delivery time. This is indeed worth checking this as well as the estimated time for tape restoration on whatever tape drive you plan to use. Remember tape does not restore instantly and can take many days if you have a lot of data.

Getting kit on site, if one still exists, is just the beginning. This is when the work really starts because all the brand new kit you have just bought is not the same as the original lost in the fire/flood/theft so restoring trouble free from your back up tapes which will hopefully have arrived complete and uncorrupted is not going to happen in all likelihood. The thing is that Windows operating systems become attached to a particular machine specification and unless it's the same specification machine you really have to start from scratch. Let's hope all those build docs are up to date with valid licence keys and that the hardcopies are not destroyed or stored worse, stored on the machines you need to rebuild. At this point there is no known timescale to get back to normal running, it may take a day, a week, even longer if they are interdependent systems. Remember tape does not restore instantly. Again in the same Symantec survey 47% of those with plans reported that it would take a full week to achieve 100% normal operations.

Meanwhile the business has ground to a halt. Customers cannot be dealt with, invoices cannot be raised, salesmen cannot sell and nothing is getting done. The main business focus is to keep customers in the boat who, although initially sympathetic lose faith pretty quickly if you are not back to normal within a couple of days. Competitors you did not know you had will be beating a path to their door with 'new customers only' deals. Reputation of a business is a very valuable asset and takes time to create but can become worthless overnight. Are you really the best supplier for them? Perhaps their previous inertia has been a just bit too cosy.

The acid test to see if this scenario could become reality is to ask your IT team if they wouldn't mind testing their DR plans next week with their annual bonuses riding on it. Only then will the caveats and favourable assumptions be added to the 'a day or two' estimate. When shit happens timescales spiral and you really need a worst case estimate to make an objective assessment of the 'risk and reward' balance of provisioning and planning for an IT disaster.

So what is the answer? Whether you have an expensive DR solution or just sitting out with your arse showing, technology has moved on. With the introduction of virtual server technology breaking the bond between Windows Operating Systems and hardware, a business can be protected to a far higher level at a fraction of the previous cost. There are many different solutions as befits a fledgling industry. Some will be more appropriate than others but most will be better than the Lucky White Heather arrangement that many businesses have relied upon in the past. One thing is for certain though, astronomically high costs are no longer an excuse for accepting the business risk that it won't happen to you.

Ten requirements for a successful virtualised IT Disaster Recovery solution:

• Fast 'Recovery Time Objectives (RTO)# -you need to back managing the situation as soon as possible
• Recent Recovery Point objectives (RPO)* - depending on your business real time replication sounds good, but if the cause of disaster is corrupted software or data, it's now in your recovery platform too !
• Short Test Time Objective( TTO)$ - systems change all the time , if the DR solution cannot be tested easily and regularly don't be surprised if it does not work
• Geographically/Infrastructure independent of the live platform - miles not yards and different utility providers
• Independent of key staff - because if the worst does happen you cannot be sure they will be there
• Easily accessible when invoked - network issues are the most difficult resolve if not planned in advance and there is nothing more frustrating than having your machines working but not accessible to the outside world
• Performance - ensure that the DR solution can cope with the load which may be increased following a disaster
• Beware virtual production machines - being so simple to create, it is so easy to forget to back up, document and provision additional DR protection
• Automate, Automate, Automate - if you rely on a manual routine it's the easiest thing to drop when faced with other short term priorities
• Green - Virtual technology makes best use of resources and economies of scale can be gained through shared infrastructure because baring an all out Nuclear attack not everyone has a disaster at the same time

How to Retrieve Deleted Files From Your Computer

Do you want to know how to retrieve deleted files? Sure, who doesn't, right? Do you want to learn all the computer hacking skills of the elite masters of computer geekdom? Or maybe you'd like to be able to type line upon line of code, and program commands and have the full knowledge of what makes a computer tick? Me neither! I mean, come on... who wants to go through all of that? Certainly not I!

Well, not to worry. There's no need to have to learn all of that egghead stuff just to know how to retrieve deleted files. These days there are software programs that know all there is to know about how to retrieve deleted files so that you don't have to learn anything - heck, you don't even need to think! All the brain power it takes for this task is enough to muster up the power to click a mouse. So how does this software know how to retrieve deleted files? It's simple, really.

For example, if you delete a file, it hasn't really gone anywhere. If you've emptied your recycle bin, it still isn't lost - it's only that your operating system now has no way of recognizing its existence. Nonetheless, it is still right there on your hard drive right where you left it. Using data retrieval software is how to retrieve deleted files because these software programs recognize such "lost" data and is able to bring it back out of hiding. Using such software, you can regain that which was once thought to be long lost and gone forever.

Retrieving Deleted Files From Your Computer

Just the thought of retrieving deleted files can by itself be a source of a sizeable headache or two. We imagine having to learn and utilize elite computer hacking skills that are just way out of our leagues, and if the files we lost are very important we can tend to panic. Where do they all go, anyways? They can't just vanish into thin cyber air. When retrieving deleted files, is there some sort of magic to it all?

Well, no, there's no need for magic, although some of the data retrieval software programs out there that can do the job may seem nothing less than miraculous. If we utilize this kind of software for retrieving deleted files, we don't need to be an elite computer hacker - we can own one. The fact is that when we delete a file, and then empty the recycle bin, we tend to think that it is just simply gone, with no hope of retrieval, as though it just disappeared or dematerialized. However in reality, it's actually still right there on the hard drive right exactly where we left it... it's only that our operating system now has no means of recognizing it anymore, that's all.

What data retrieval software does as it begins retrieving deleted files is it simply searches, finds and recognizes these files without requiring the operating system to be able to wrap its brain around it. Further, if that file has even been partially overwritten by other files newly created in its space on your hard drive, these software programs actually mend the corrupted parts of the file so that it will complete the task of retrieving deleted files in one piece. Now isn't that pretty darned cool? This is why data retrieval software is the best, most efficient and fuss-free way to go about retrieving deleted files.

How to Retrieve Deleted Data From Your Computer

Are you looking to find out how to retrieve deleted data? It's quite simple, once you realize a few fundamental facts. See, when we delete a file, whether we mean to or accidentally, and then we empty the recycle bin, we tend to think it's lost and gone forever. The actual fact is that it's simply irretrievable by our operating system, yet nonetheless it is still there on our hard drive, right where we left it. This is why we need to utilize certain software programs to fish it out of hiding.

Now, in learning how to retrieve deleted data, we also need to understand that while our deleted file still resides somewhere on our hard drive, it can get partially overwritten by other files we write, programs we download, or images that we may wish to store on our computers. This is usually no problem for data retrieval software, as most of these types of software programs can rebuild the small parts and areas that can get overwritten.

Using these software programs is how to retrieve deleted data in the best way because you no longer need to have the hacking skills of those brilliant computer geeks out there - these software programs are like having your very own computer hacker, only without the geeky part. There's no need to keep it fed with Twinkies and Jolt cola, you just make a few clicks with your mouse, and sit back with a cup of coffee while it works it's magic to bring back that which was lost. This is how to retrieve deleted data in the easiest way.

Fully Utilize the Full Benefit of a SAN With Automatic Defragmentation

"Out of sight, out of mind" can be an interesting phenomenon. An example of this is a large piece of furniture, such as an armoire, that's been standing in a hallway for years and causing people to curse and move around it, or bumps their toes or their heads as they rushed by. Finally someone in the household gets fed up and has the armoire moved out of the hallway and into the garage. Problem solved!

Or is it? Just because that bulky armoire has been moved doesn't mean it isn't taking up the exact same amount of space; it's just doing it somewhere else. Someday in the not-too-distant future somebody's going to get mad because they've been having trouble getting the car into the garage and probably yell at the person who moved the armoire there. It's still causing the same problem!

In the computer world, file fragmentation has always been a serious problem needing to be constantly addressed. When it comes to servers, fragmentation becomes much more of a problem simply due to the high number of files being created, modified and deleted by multiple users. Fragmentation not only increases dramatically but it also impacts a wider number of people and their production.

In information technology, a storage area network (SAN) is an architecture to attach remote computer storage devices (such as disk arrays, tape libraries and optical jukeboxes) to servers in such a way that, to the operating system, the devices appear as locally attached. Although cost and complexity are dropping, as of 2007, SANs are still uncommon outside larger enterprises. Operating systems still view a SAN as a collection of LUNs, and usually maintain their own file systems on them. These local file systems, which cannot be shared among multiple operating systems/hosts, are the most reliable and most widely used. Thus, sharing data between computers through a SAN requires advanced solutions, such as SAN file systems or clustered computing. Despite such issues, SANs help to increase storage capacity utilization, since multiple servers share the storage space on the disk arrays.

SAN was seen as a brilliant way to move much of this traffic off of servers, which it was and is. Because stored data does not reside directly on any of those servers, server power is now used strictly for business applications and network capacity is freed up for other purposes.

But a SAN still consists of disk drives. Fragmentation is still very much a performance-crippling problem on those drives, and (in a similar way to that armoire) just because it got moved off the network does not mean that it isn't there. In fact, because there are additional steps to requesting and accessing files from a SAN, fragmentation can even have more of an impact from the SAN than from a local or server drive.

Utilizing otherwise-idle resources, defragmentation occurs whenever and wherever possible so that performance is constantly maintained, and there is never a negative performance impact from a system defrag.

With some Disk Defragmenters, fragmentation can be removed as a problem, and the SAN solution truly works as it intended. Unlike the armoire in the garage, it is completely gone.

Recover Deleted Files - Vista

When using today's state of the art data retrieval software to recover deleted files, vista is not a requirement. Even the most recent data retrieval software can work with computers using very old operating systems like Windows XP or Windows 2000. Some people today still have computers that use the old Windows 98! These people as well, can rest assured that they can recover deleted files, vista or not.

But really, whatever version of whatever operating system you use is of very little consequence, as data is all "lost" and restored the same way. It all has to do with how your hard drive crunches up bits of data to store and even hide it all away in its little hiding places. The fact of the matter is that data never really leaves your system - it always stays on your hard drive in one form or another, and is thusly always retrievable. Software tools used for data retrieval can recover deleted files vista or not, it generally makes no difference.

There do exist some data retrieval tools that when used to recover deleted files, vista or other operating systems may not work, but these are usually of the type made years ago, and are often freeware. Today's data retrieval software can recover deleted files, vista or Windows 98, no problem at all. It's all in where you find it, and how old the software you find may be. Use today's data retrieval software, and you'll simply have no need for any worries at all.

Restore Deleted Files - Vista

In the task to restore deleted files, vista users may feel that there can be no problems... and usually, they are correct. But really, it doesn't matter what operating system your computer happens to be using, as today's data retrieval software can restore deleted files, vista or not. The fact of the matter is that lost data doesn't hide out in your operating system - it hides out inside your hard drive.

Even if your machine was ransacked by a horrendous virus you might've contracted from somewhere online, and you totally reformatted your hard drive an then reinstalled Windows, it's all good... the data is all still there, believe it or not. Data never really leaves your system after all, and this is why people from the FBI or CIA can nab anything they want to get their greedy little hands on, even if the computer in question has been completely purged of all data - it's all still there somewhere, and only needs to be coaxed out of hiding. It's all in the software. You can restore deleted files - vista or 98 - it makes no difference.

This can be a reason for many to relax and have no fear, as even those with the more antique types of computers, such as those that just aren't capable of handling anything newer than Windows 98, can still restore deleted files, vista not being a prerequisite. Today's data retrieval software is more than capable of handling the task, and it makes no difference what operating system your computer is using, plain and simple.

Can I Recover Deleted Files? How to Retrieve Deleted Files

Many have asked, "Can I recover deleted files?" - and the answer of course, is a resounding "Yes!". Ah, but you might be asking "How can I recover deleted files?"... well it's really quite simple, actually. It's all in the software. But many worry as to how far gone is gone, as far as lost data is concerned. For example, picture this; I surf the internet for a bit, and then I come across a virus that just eats the heck out of my computer. My PC just freezes there, unable to do anything. What have I got left to do? Nothing - I have to completely reformat my hard drive, and reinstall Windows. So... now all my data is lost and gone forever, right? Or is it still possible - can I recover deleted files even after all this has been done? Believe it or not, yes I can!

You see, data never truly leaves your hard drive. It's always hiding out somewhere on it, even if you've completely purged the system. Knowing this, you never again need to ask "can I recover deleted files... " because you know that it's still hiding out somewhere on your hard drive. Now the only trick to figure out is how precisely to coax it all out of hiding.

This is where today's data retrieval software comes in. Using such software, can I recover deleted files from even the tightest clutches of the greediest of hard drives? You bet! It's all just a matter of a few mouse clicks, and I've gotten back that which was once lost and gone - and you can do the same.

Hard Disk Data Recovery - How to Restore Deleted Data

Hard disk data recovery can be a completely simple operation. It used to be that in order to perform any hard disk data recovery, we either had to be an elite computer hacker ourselves, or we at least had to know one. These days that has all changed, and happily for the better. The main fact to know about hard disk data recovery is plain and simple. You can perform it in one of two ways; hack it out on your own, or use software tools created specifically for data retrieval.

The brilliance of the latter of these two choices is obvious - we don't have to be a member of the computer geek squad, or some programming genius with all of our thoughts written in binary code. We can just sit back, perform a small few mouse clicks, and then go make a cup of coffee while the software chugs away at the task of hard disk data recovery. A few minutes later and there we have it - all of the data that we had lost track of, and indeed, even some that we forgot we had in the first place.

The best part of this whole venture is that data never leaves your hard drive. Even if you went mad with frustration because a virus forced you to reformat the hard drive and reinstall your OS, leaving you to think that you lost an entire computer full of records, the truth is that you really didn't. It's all still there on your hard drive, believe it or not, and data retrieval software can attack the problem of hard disk data recovery even in such a dire situation.

Recover Hard Disk Files - How to Recover Deleted Files

If you've ever needed to recover hard disk files years ago, you were probably either a member of the elite, computer savvy, programmer type nerds in school who could hack anything including the computer servers at the Pentagon, or you knew someone who was. Back in the day, it was just a completely frustrating task for some of us who weren't the type to think and dream in binary code, but just utterly impossible for most of us. Just thinking about such attempts to recover hard disk files back then just hurts my head something fierce.

Luckily, that has all changed these days, as there is no longer any need to know the ins and outs of your computer so extremely. Now when we need to recover hard disk files, we have software tools specifically created for retrieving lost data, no matter how it all came to be lost. Even if a virus caused you to totally erase everything there ever was on your hard drive, and reinstall Windows all over again, the fact is that all that data is still on your hard drive somewhere. Truth be told, data never leaves your hard drive, but instead is embedded in little hiding places just waiting to be coaxed out.

With the use of today's data retrieval software, the need to recover hard disk files is easily met with just a small few clicks of your mouse and then you just sit back with a coffee and watch the magic happen. Really, it's just that simple. In fact, it's just like having your own computer nerd at your beck and call whenever you need him. Using data retrieval software to recover hard disk files is the way to go.

Do You Back Up Your Website-Ecommerce Site Files?

Do you have a backup of your website files? If your website goes down and the hosting company cannot bring it back up, will you be in deep trouble? While most hosting companies back up their servers regularly, it's still a good idea to back up your files. If you own an e-commerce site, you especially should back up often, since your hosting company's backup may be several days old, and you risk losing all of your more recent transactions.

I'd recommend taking it upon yourself to do the backups rather than putting all of your faith in someone else. With a proper backup, in the event of natural disaster, server trouble, disgruntled employee, or any other problem, you can have your site back up in minutes instead of waiting precious days or weeks, or worse - losing data without ever recovering it.

In order to backup your website files, you will need an FTP program (FTP stands for File Transfer Protocol). You can find a good FTP program online, usually with a free trial period, and not expensive to purchase.

As with regular computer backups, you should keep a copy off-site as well. If your site doesn't change often, then I'd back it up monthly, and then again every time you update any of your pages. If it is updated regularly, then daily or weekly updates are in order. It's also a good idea to keep multiple backups done on different dates - this way if something goes wrong with a back-up, you can revert to the next most recent backup and likely find the files you need there. Remember to check and test your backups and make sure everything is actually there!

E-commerce sites or other sites that use a database: E-commerce sites that receive orders daily should be backed up daily. Also, if you have an e-commerce or other site that uses a database, you need to back up the database as well. Ask your hosting company for the url to access the database, as well as the username and passcode. You will need to export the database. Here too, I recommend having several versions saved by date, not just one backup. If the most recent one fails for some reason, you can revert to the next most recent. I've seen firsthand how people have lost their entire website, and thousands of dollars in business, due to some natural disaster or server/computer failure. Perform a backup regularly and save yourself the grief, and your site will be back up in minutes.

SQL Server Snapshot - How it Works

SQL Servers have been growing in business exponentially since they were created in the 1970's. First created by IBM in San Jose, California, SQL did not become a standard computer language until the mid-1980s. Since that time, during its growth, there have been many upgrades and changes to the SQL relational database management systems, one such upgrade is the SQL server snapshot.

A SQL server snapshot is essentially what it sounds like, it is a snapshot of the system that is stored and used as a primary system. When a snapshot occurs, the information is stored in the main drive and then further information created after the snapshot occurs is stored in a new data is stored in what is called a sparse file. A snapshot creates a backup of the system at that time, and uses 90% less drive space than backing up the system does. This information is stored for as long as the user requires it, and can be dropped when no longer needed.

The purposes of a SQL server snapshot vary depending on the needs of the user. In some cases, it is used simply to back up the system without having to use so much drive space during the working day. In other situations, it is created when data is perceived as "ideal" and any new data needs to be compared to the data that was previously acquired. This information can be stored indefinitely and new snapshots can be created at any point to continue tracking specific data. When saving the user should simply take the name of the data and add a time stamp to it. This will ensure that there is no confusion when accessing the information as to what its purpose is.

When a SQL server snapshot is dropped, the new information and the previous information join to form a completely new set of information. The information from the snapshot is no longer available and cannot be referenced for projects or projections. When the decision is made to drop it, it is vital that the project manager or user understands that it will become irretrievable.

While some business may never drop a SQL server snapshot, others may find that they simply want to test their data against studies that may have been conducted or to simply experiment with different ways of looking at their data. Once the information is retrieved the SQL snapshot is dropped in favor of new testing, or they return to their regular data consumption. Companies that track long-term data may never drop a snapshot, and the SQL servers are designed to function either way.

Formatted Data Recovery - What to Do When Everything is Lost

So you accidentally formatted your hard drive or storage device. Do not panic, or if you have already; please stop and read on. Whether you realize it or not, usually when you delete files on your computer, they are not removed immediately, they are merely removed from the computer's "sight" and by extension, yours. This even applies to drives that have been recently reformatted. What you need is to perform a formatted data recovery, which can be done by a number of file recovery software solutions. Below are a few you should consider.

"Recover My Files" is a Vista compatible program developed by GetData Software. The program also works for versions of Windows from Win 98 and up. Although the software is shareware and costs $60 for the full version, you can download a free trial which will allow you to easily recover your files. Naturally, if you only plan to use this as a one-time occurrence you can use the trial for formatted data recovery and not pay anything. However, if you work in IT or frequently lose data on your home computer, then the purchase price is well worth it.

Next in the list is VirtualLab Data Recovery by BinaryBiz. This program also works for all versions of Windows since 98 including Server and Vista.

Ease the Headache of Saving Files Through Differential Backup

In a lot of multimillion companies today, data is one of the most prized assets. This is definitely true to conglomerates with substantial amounts of dollars of payables and receivables. If multiple will be lost, then you can expect for everything to be duly affected. The Chief Finance Officer would not even wish to imagine how to remedy the situation since it is a complete headache. It would definitely require loads of work in order to restore the files that were missed out. To avoid such incident, differential backup is required.

The differential type of backup pertains to the backing up of all files that have been created and modified since the previous full backup. Using such has its very own advantages, like it will lessen the period of saving entries in comparison to other types. But like anything else, this method also has its share of downsides. When you store a lot of files over and over again, the memory will be full, necessitating you to delete some files in the long run. However, data is significantly important so scrap these thoughts. In such case, you will then have to buy another backup to support other entries you will create in the near future.

Putting that the company you are working with only has a few data, you can then choose to do the overnight full backup. With that, only two tapes would do. The first tape is where you will initially store the entries while the second tape will serve as an alternative, especially in times of technical malfunctions. You have to greatly consider the advice because it would be highly complex to retrieve a certain file. Once done, make sure that the two tapes are kept in a secure location to ensure that nothing will turn out to be defective.

Remember that when you are targeting a full backup, each of the data being "cooked" contains the library attribute in its settings at zero. The archive described here is a flag saved for entries that have been developed or changed. Such will tell the user that the file has to be stored. This is now where the differential type of backup is more reliable than a full backup. The said type, even if the memory will be consumed in the long run, will only keep data that have been altered from the recent performance. Once the entries are secured, the library attribute is now one.

When you are using Windows application, you have the luxury of peeping through the library attribute for any data by simply putting the cursor on the name and clicking the right portion of the mouse. A box will then pop out and proceed to "Properties" then "Advanced." With the uncomplicated steps, you cannot help but be thankful to Bill Gates by sharing his brilliance to the world.

Like what was mentioned earlier, the above is only true to companies having few data. But if you are connected to a firm with countless entries to be saved, you will come to appreciate the differential type more than the full type. This is because you will be entitled to lesser hassles in waiting for all the files to be secured.

So, if you have numerous data for keeping, settle for differential backup immediately.
