Data management covers the entire system associated with organizing data as a helpful resource. Mainly, data management is the consolidation of information in such a way that data is easily maintained and capable of being retrieved when required.
The competitive environment requires businesses to capture, process, and study huge volumes of data. It may not always be possible for businesses to handle all the data that forms a part of their functioning. Apart from structured data, businesses are also required to deal with unstructured data in the form of e-mail, and images. These are to be stored for different strategic, trade and regulatory needs. Hence, businesses employ the services of data managers to handle their resources. Data management companies handle data with a comprehensive plan, which encompasses human as well as technological aspects. These aspects combine to achieve the basic aim of maintaining data without any fuss, and facilitating easy retrieval of data whenever required.
Data management companies assist businesses in developing policies and systems desirable to identify and exploit market opportunities. They help businesses in satisfying the changing demands of customers. These companies have professional specialists who have years of expertise in this field. They aid businesses in obtaining, replicating, transforming, and managing data to provide it to executives for the purpose of decision-making.
Data management companies also deal with data mining. Data mining utilizes computing power and highly developed analytical techniques to determine useful pattern relationships from large databases of the customers.
Data management companies can mine the data of their clients, or the data that they collected from their clients. Most importantly, they can show their clients how to understand data and use it to their best advantage. The data mining services offered by companies combine leading tools and statistical analysis techniques to create strategic intelligence from corporate data. This involves examining historical detail transactions to identify trends and establish and disclose hidden relationships for future predictability.

Five Steps to Data Storage
Wayne Hall examines how DVD and Blu Ray discs are becoming a real option for firms seeking long term storage.
Microboards's storage specialist Wayne Hall discusses some of the key points to address when planning your organization's storage system.
Storage is a complex business these days. Businesses face an almost overwhelming choice of differing technologies and vendors, and it can be very difficult to separate marketing hype from fact and decide which systems are the best for your organization's requirements. The situation is further exacerbated by the increasingly complex raft of corporate governance legislation and industry regulation that businesses must comply with, since much of this involves a large degree of data retention which requires a robust long term storage solution.
Before rushing into a decision about which solution to invest in, and potentially making a costly mistake, it's wise to assess the company's specific requirements, in a step-by-step process taking into account: business needs, the regulatory environment and the budget available. Here are some points to consider:
• Can you afford to be locked into a proprietary system or a specific supplier?
Not all storage devices make it easy to transfer their media to an alternative device. If the hardware you are considering fails, how easy will it be to remove the physical media and load it onto a replacement device? Worse still, if the hardware supplier should ever go out of business, will it be possible to transfer your backup media to third party hardware?
• How long do industrial or company regulations require data to be held?
Longevity is a serious issue. Systems which rely on magnetic media such as tape or hard discs are prone to corruption due to electromagnetic interference, and mechanical failure. This means that the data they store will have to migrated to new systems at regular intervals, two to three times per decade in order to maintain data integrity; this can add significantly to the total cost of ownership. Optical media offers a far greater lifespan, with DVD and Blu-Ray often certified to last up to 50 years and with the new technology available there is practically zero chance of corruption.
• Where will the hardware reside?
Server rooms are often in basements that may be vulnerable to flooding, or physical storage areas where they are susceptible to being knocked around. What would happen if the data storage unit was physically damaged – would the data survive? Server rooms can also generate a lot of hear and it they are individually cooled, the risk of a system failure is significantly increased, so they require air conditioning systems which can be expensive to install and run.
• How quick and easy does the retrieval process need to be?
This can be influenced by the number of drivers, from compliance requirements to simple business logistics. How often is it likely that stored data will need to be retrieved, and how quickly does the retrieval request need to be fulfilled? Tape backup systems can be slow at the best of times and a high number of retrieval requests can really grind things to a halt. Hard Disks and DVD/Blu-Ray Libraries offer much faster data retrieval and are better at handling higher volumes.
• What is the budget available?
Will the budget for the project be enough to buy the right kind and the necessary volume of storage? While the traditional storage technologies such as Tape and Hard Disk have held the upper hand over DVD in terms of storage capacity; the arrival of Blu-Ray has completely altered the landscape and future developments such as holography promise to provide even more competition. Currently the cost per GB favours Tape and HDD, however with Blu-Ray media costs predicted to fall consistently, it will only be a matter of months before Blu-Ray media becomes more competitive. On the hardware side, Blu-Ray already offers a lower total cost of ownership per GB than either Tape or HDD systems. DVD/Blu-Ray storage libraries offer solid, reliable long term storage, faster retrieval times that tape based systems and because they're based on such a ubiquitous media format, there are no worries about future compatibility problems.

Truths About Data Recovery Software
There may have been instances in your life or career where your day starts with a hard disk crash or a physical memory dump. If it hasn’t happened to you yet, it can happen anytime and catch you completely unawares. It can be very frustrating to loose all the important data, those great presentations, client briefs, portfolio, 3 years of research etc. If you install data recovery software on your PC, then you can retrieve all the lost data. A computer is not a perfect machine and the fear of data loss is real. Hence, we are going to share some tips and useful information on data recovery software with you.
Why is Data Recovery Software important?
Data recovery is important because most of the data on your PC or Laptop is valuable. But what is data recovery? It is retrieval of almost all the data that has been accidentally deleted from your computer or has been erased due to a hard disk error, virus attack, or bad script. You can use DOS commands to retrieve data but it will be partial recovery only. So the best solution is to have data recovery software that can retrieve the full data or undo the loss.
Most of the data recovery software available in the market can recover data from corrupted file systems like Windows (FAT16, FAT32, NTFS, NTFS5), Unix (UFS, EAFS, HTFS, VxFS, FFS), Linux (Ext2, Ext3, JFS, ReiserFS), Apple Macintosh (HFS, HFS+) and Novell Netware (NWFS, Net386, NSS). The data recovery software can also recover data from corrupt access databases, corrupt zip files, word documents and excel files.
Which data recovery software should I use and why?
There are many firms who sell data recovery services, but there are many brands who sell data recovery software. At times, it can be difficult to decide, which product will satisfy your need or requirements completely. One such data recovery software is The Undelete 3.1.1. The salient points of the software are that it is easy-to-use and it can provide a powerful backup program for Windows 95/98ME/NT/2000/XP. This data recovery software can work with FTP, local networks and even CD-R/W. It is useful data recovery software that applies powerful algorithms and methods and it can recover files that have been damaged, lost or deleted due to a power supply failure, program bugs or virus attacks. The Undelete 3.1.1 data recovery software can recover files with extensions like DOC, PDF, RTF, XLS, MDB, PPT, Visio, CSV, HTML, TXT, CPP, PAS, EML, and INI. It can also recover audio and video files with extension MP3, WAV, AVI, WMA, MPG, MOV, and ASF.
There are also data recovery software’s, which have specific use based on platforms, files and functions. You will find data recovery software that offers a range of file system utilities as well as data recovery service. These services enhance recovery of lost data due logical hard drive failures.
What should I look for in Data recovery software?
When you go out in the market to search for data recovery software, you should be able to compare various products based on five important features. These are:
Feature Set
Ease of Use/Installation
Recovery Effectiveness
Search Capabilities
Help/Documentation
The bottom line is that basic data recovery software should be able to recover Compressed Files, and Encrypted Files, should provide email recovery, network recovery and create image files. It should be able to recover from the recycle bin, damaged files, power failure, Format Disk, changed, or deleted partition, disks with bad sectors etc. It should support file systems like NTFS5, NTFS, FAT32, FAT16, and FAT12 as well.

Backing Up Your Data to Prevent Losing It!
Developing a disaster prevention and recovery plan, often the most overlooked or outdated of any business plan, can be the difference between keeping your company in the black and closing your doors forever.
The fact is that US businesses lose over $12 billion per year because of data loss. To prevent such costly loses to your business experts recommend backing up your critical files.
At very least, businesses should backup critical files on CDs or external USB hard drives on a regular basis. If a business’s data is updated on an hourly basis, it needs a more continuous data storage option. However, if backing up data on a daily or weekly basis will allow a business to retain all of its pertinent data, then that’s the best option.
The Products of Data Protection
There are several vital elements that come into play when it’s time to develop a data protection strategy. There are various data protection solutions—and a wide degree of costs associated with it—but they all come down to capacity, data transfer and data restoration.
Magnetic tapes are still the storage medium of choice for most businesses because they have a long shelf life that make archiving data reliable. Formerly, data transfer rates were relatively slow—11-30 megabytes per second. But high-end magnetic tape drives have more than double that speed and can store information in the terabytes.
Hard drives are a cost-effective alternative to magnetic tapes and can be protected with RAID to ensure hardware fault tolerance, something that magnetic tape backup doesn’t offer.
The key to both media is offsite storage. Because fires, floods and other natural disasters can wreck havoc on your equipment, giving IT managers the ability to recover most of the data from an off-site location is key to a successful data protection strategy. Co-located servers and storage methods will be unusable.
While it is always a good idea to backup your critical data, if your data is stored at the same location as your server—and you experience a natural disaster, a fire or flood—the odds are that you will still require data recovery on the hard drives, or tape restoration to get your data restored.
The Downtime of Data Restoration
The magnetic tape drives and hard drives are common ways to make sure you’ll always have critical data to run your business. But since data recovery takes time, you need to consider restoration time in your data protection strategy.
If your business can never suffer downtime, then perhaps you should consider remote mirroring or electronic vaulting. Like the storage media, both of these options have certain advantages.
With remote mirroring, you’re duplicating one or more disk arrays. You disassociate one at night and perform and offline backup of the array before re-associating it. The downtime is only 15 minutes in a 24 hour period.
The downside is that remote mirroring is expensive to implement because of the high-throughput network link and low latency that’s needed to maintain synchronous communications.
Reducing that expense is electronic vaulting, a method by which transactional information is written into log files, and is then forwarded to a backup site every few hours. Because of the asynchronous form of communication, bandwidth and latency requirements are less of an issue.
The Key of Data Strategy
Having what you believe to be an outstanding data backup system is likely not going to be useful unless testing it is part of your plan. Products, installation and maintenance make up only half of a data protection strategy.
Your test should verify how long it will take to recover data as well as if the backup process will corrupt the data. Recovery tests should be run fairly often—at least quarterly.

OST File Recovery and PST File Recovery
Email communication has expanded itself from professionals to normal home users. As a child enters into teenage, he becomes familiar with the power and usefulness of email communication and uses emails to correspond within his circle of friends and relatives. If we quickly look at some of the public email portals like Yahoo, Hotmail, Rediff etc; it can be analyzed that these portals regularly increase email storage limits for its users and as long more space is provided will thus encourage the user to utilize it.
Email communication proves more useful in the corporate world where hundreds of emails are exchanged daily between the professionals. They could be meeting notices, memorandums, important business attachments or simple emails of well being. If the importance of email communication has increased, so has increased the importance of data storage and the level of corruptions of email messages. This importance has resulted into duplication of data and information, data archives, and waste of hard drive storage space.
Email Storage :
As you receive many emails in a day, have you ever wondered where these emails get stored? The answer could be an email server or on the user’s computer system. MS Outlook and Outlook Express are the widely used email clients because of their ease of use and user friendly features. While working on MS Outlook, the email files are stored in PST and OST file formats and an exchange server is maintained to handle the incoming and outgoing emails. Now arise the common questions; what is exchange server, .pst files and .ost files and how are they used to store emails?
Microsoft Exchange Server -
Microsoft Exchange Server is a messaging system which supports transfer of internal and external electronic messages. The application is widely used in organizations where Microsoft infrastructure solutions are used. The exchange server stores data in highly organized relational database with the help of algorithms thus helps in transfer of mails and manages communication between other Exchange servers also.
How does Exchange Server work?
As the Exchange server stores messages and manages incoming and outgoing process of emails, the working of the messaging server also becomes a crucial point. The process of receiving, sending and managing the messages by Exchange server is as follows:
Step 1: The client connects to the server and sends the message.
Step 2: The exchange server then processes the message and determines saving location in the messaging database.
Step 3: The recipient of the message is notified by the server.
Step 4: The client to receive the message connects to the server and receives the message.
The simple working of the exchange server makes it easy for us to send and receive messages, thus transferring data electronically.
MS Outlook – Personal Storage Files -
“The file where MS Exchange server delivers messages”
The Personal Storage File (.pst) is the most robust storage container of emails and MS Outlook has the ability to store and deliver messages in the .pst file format, other file types can also be stored inside the PST file. But the PST file can get corrupt due to accidental file deletion, virus attacks or it can get damaged internally causing into data loss. There are number of email recovery and pst recovery software which effectively recovers mails and data from the corrupt pst files.
MS Outlook – Offline Storage Files -
“The storage file where emails and other information can be stored, which can also be accessed offline.”
In the corporate arena, Exchange Servers are used to store email messages. The Outlook Offline Storage Folder (.OST) in Microsoft Outlook provides unique synchronization method with an Exchange Server and existing mailbox accounts. The OST file gets stored on a users computer system which constantly gets synchronized with the Exchange mailbox account, which results into duplication of data on exchange server and on the user’s system. Access to .ost file requires an Exchange mailbox account, and if the mailbox is damaged, missing or removed, the .ost file will not open. For this you need to convert the .ost file to .pst file on your own or try the exchange ost recovery software.
Here I would like to guide you with some simple steps, following which you can convert the damaged .ost file to .pst file successfully in Outlook 2002 or 2003. This is the method which worked for me:
1. Backup the ost file(s)
2. Rename the outlook.ost file to outlook.pst file
3. Use scanpst.exe from Outlook 2002 to repair the outlook.pst file. (C: Program FilesCommon FilesSystemMSMapi1033)
4. Rename outlook.pst back to outlook.ost
5. Run OST to PST which will then successfully convert the file to outlook.pst
6. MS Outlook will then open the outlook.pst file
OST/PST file formats are very complex and are designed around relational database concepts. The messages in these files are organized in hierarchical format using folders to store the messages. If the above mentioned steps do not work in your case of corruption, then it might be due to major corruption which can be effectively repaired by the ost recovery software. There are number of OST file recovery and PST file recovery software to convert and repair your damaged email files.
Nucleus Data Recovery: The Solution Provider
Nucleus Data Recovery is the premier provider of data recovery software and data recovery services. Kernel Recovery for OST is such corrupt ost recovery software which effectively converts .ost files to .pst files which become inaccessible due to virus attacks, exchange server crashes, accidental deletions and database corruptions. The pst recovery software effectively repairs outlook pst emails with complete emails, attachments, email properties etc. The ost conversion software is powerful and equipped with proprietary QFSCI technology to perform effective conversion and fast recovery of emails, attachments, images etc.
