What happens when you are working on a special project or document and your computer system displays a blank screen? Or one of the partitions is not recognized by the BIOS - It could be anything. So is this a warning from your computer about some mis-happening about to happen such as hard disk failure, system crash or some other problem that caused your system to shut down? Don’t be surprised! This could lead your computer system to become dead and all your valuable data is gone forever. But Stop, Don’t Panic, the relief is there.
“The data which appears to be lost and inaccessible, in real terms is not lost forever. The lost data can be recovered with the help of professional data recovery utilities and services.”
Many times organizations or individuals do not give much importance to such kind of incidents and after wards suffer major loss of their valuable data. In such cases when the computer system shut downs or reboots or there are indications of disk failure, it means that your computer system needs your immediate attention.
You need a data recovery solution if you experience inaccessibility of files and folders, unrecognized format, virus attacks, accidental deletions, permanent deletion of files, inaccessible partitions, corrupt documents, unexpected system shutdowns, error messages while opening a file and there are endless reasons due to which you cannot access your data.
As the article targets towards importance of data recovery, the first question arises - What is Data Recovery?
Talking in simple terms, it’s like repairing a broken toy with the help of glue and making it usable again. Here, the broken toy is your damaged and corrupt storage media and glue refers to data recovery software and services which instantly gets back your lost and inaccessible data to life. In technical terms, Data Recovery is defined as a scientific approach followed to get back the lost and inaccessible data. This can be made possible through data recovery software utilities and services.
How useful are Data Recovery Software?
Data Recovery software effectively recovers and repair files, databases, storage media, corrupt partitions and brings back your data safely. Data recovery software are helpful and effectively recovers back your lost, deleted data, which can be easily purchased through on-line sale transactions. Almost every data recovery company provide FREE demo version of their data recovery software range.
This Free demo version is the best evaluation technique for a user. You should always try demo version of the software before deciding to purchase it. Test your damaged drive or file with the demo version and see whether the software is capable enough to recover back your data. It is a reliable means to test features, performance, speed, user friendliness of the software. If the demo version displays your data then you can purchase Full version of the software as the demo versions might not allow you to save the recovered data.
The number of data recovery software present in the market promise to recover data from the damaged or corrupted file systems: Windows (FAT16, FAT32, NTFS, NTFS5), Linux (Ext2, Ext3, JFS, ReiserFS), Unix (UFS, EAFS, HTFS, VxFS, FFS), Novell Netware (NWFS, Net386, NSS) and Apple Macintosh (HFS, HFS+) and also from corrupt access databases, MS backup, corrupt zip files, corrupt excel files and corrupt word documents.
So whenever you face situations of data corruption or data loss, always follow the rule: “Test, Evaluate and Purchase!!!!”
How useful are Data Recovery Services?
Following the scientific approach, data recovery services are performed in Class 100 Clean rooms with high biometric security to recover every bit of data. These clean rooms should be equipped with the entire infrastructure like, air flow rate and direction, pressurization, temperature, humidity, specialized filtration and other standards required to perform data recovery.
Data Recovery Services are usually performed when data recovery software are unable to recover your data or the complexity of the damage to data is to such an extent that specialized attention of the data recovery technician is required. This generally happens in cases when your hard drive or storage media indicates the following symptoms: clicking noise from the hard disk drive, lots of bad sectors, S.M.A.R.T failure, drive not recognized by the BIOS, fire and water damage, hard disk component failure, computer is not bootable and many other undefined reasons.
The specialist data recovery service providers offer services of data recovery from hard disks of desktops and laptops, RAIDs, Tape media, Pen drives, Zip drives, Compact disks, DVDs, Digital Cards, Memory Cards etc where data gets lost due to Logical and Physical crashes.

Data Backup-Recovery and CYA
Has it happened to you yet?
Floppy disk with important data went bad?
CD or DVD with your favorite pictures got scratched?
Hard drive crashed without any, warning PC won't boot up?
Unless you have personally experienced the loss of data, whether it is pictures, important documents, spreadsheets, databases, music files, graphics or software, you will never understand why it is so critical to do backups on a regular basis to protect yourself.
Simply put, Backing-up is the activity of copying your files or databases so that they will be saved in the event of an equipment failure or other catastrophe. Backing-up is usually a routine that is part of the daily operation of large businesses using mainframes as well as by the management of smaller business computers. For home personal computer users, backing-up is also necessary but usually neglected.
The retrieval of the files you backed up is referred to as restoring them.
In the field of information technology or data processing, backup refers to the copying of data, so in the event they are needed, these additional copies may be restored after some type of a data loss.
Backups are normally used for two purposes:
1. In the event of some type of disaster, they are used to restore a computer to an operational state following the disaster.
2. In case files have been accidentally deleted or corrupted, you can restore small numbers of files.
What are the types of backups?
1. Full backup
A backup of all (selected) files on the system. This type of backup is essentially a waste of time, for the simple reason that in order to restore files, the operating system must be intact and bootable.
2. Incremental backup
A backup that only contains the files that have changed since the most recent backup (either full or incremental).
The advantage of this is quicker backup times, as only changed files need to be saved.
The disadvantage is longer recovery times, as the latest full backup, and all incremental backups up to the date of the data loss need to be restored in the appropriate order.
3. Differential backup
A cumulative backup of all changes made since the last full backup.
The advantage to this is the quicker recovery time, requiring only a full backup and the latest differential backup to restore the system.
The disadvantage is that for each day elapsed since the last full backup, more data needs to be backed up, especially if a majority of the data has been changed.
No one can ever predict if and when his or her hard drive will crash or when a floppy disk or cd will malfunction. It is no fun when it happens and you find out you has lost data of some type. Determine what you have on your computer that is extremely important to you and set up a plan to back those files up on a regular basis. Very small files can be copied to a floppy disk; large files can be copied to a CD or DVD. Keep a log of what you backup and when, so if you have to recover or restore a file or files, you will be able to easily find what you need.
There numerous software programs available to backup/restore files. Most of them allow you to compress the data that is to be backed and this simply conserves space on the backup medium. For large numbers of files or very large files, this is a good way to go. If you only have a few files and they are small, there is really no reason to compress them. Keep in mind that if you compress the files during backup, you will need the same software to decompress the files if they have to be restored.
