In these days computers are used everywhere across the world. They safely store our large amount of data and information in files. And for their safety we create backup files which contain the copies of our databases.

"Generally backup is a process by which we make the copies of our files and databases stored inside our computer system which helps us in the situation of unwanted data loss."

We can easily create backup by Windows NT-Backup utility tool which is an inbuilt program in all windows. But in Windows 7 we don’t get it, so to create backup file in Windows 7 we need to install ntbackup.exe which can create backup in Windows 7. After creating backup files we our databases are well protected and secured and through backup files we can extract or recover our all data at time of sudden data loss or data corruption. Backup will help us to retrieve all the files and data from our computer system which has been damaged or lost due to any reason.

Backup can be easily created by NTBackup utility which is freely provided by Microsoft Windows. It helps users to make a backup file with .bkf extension (contains anything like images, videos, sound files, documents, applications, etc.) for their system’s databases. Though, the backup file is used to restore the original database in the critical situations of data corruption and data loss, but however the Backup file can also be damaged. There could be several reasons behind corruption of backup file (.bkf).

Reasons of BKF file corruption: Interruption in backup process, unsupported media errors, virus infection, improper system shutdown, CRC errors and catalog files missing, backup interruption and hard drive failure.

Whenever users try to open backup files which are badly corrupted they can’t be opened. At the same point of time some errors messages appeared on the screen as a warning which indicate that backup files are corrupted, damaged, inaccessible, useless or unreadable and thus they need to be repaired. Few common errors messages which frequently appeared on the screen are following:

• The backup file is unusable. You must erase it, or choose another file.
• The fixed media is full. You cannot back up all of the specified data to this disk device. The backup operation will stop.
• The backup file contains unrecognized data and cannot be used.
• An inconsistency was encountered on the requested media.

If those errors are frequently appeared on the screen it means backup files are inaccessible and they need to be repaired.

Whenever any user deals with such a problem of backup file corruption, he or she wouldn’t have any option except to restore backup databases which can be done only by recovery software program. Due to a fact that backup files can’t be repaired manually, so it is just useless or worthless to waste our time. Taking help of software tool is always a right decision. It doesn’t only repairs the corrupt backup files but also saves our precious time. SysInfoTools BKF Recovery is helpful tool for us to recover the data from highly corrupt or severely damaged backup files. With the help of this tool we can easily make our backup files fresh and clean as they were before. It helps users to recover the maximum possible data from the corrupt inaccessible backup files. While recovering the data it uses advanced algorithm technique which performs a quick recovery action without affecting the originality of data. After successfully recovering all the data it allows users to select the location at where the recovered data has to be saved. It has advanced and friendly GUI (Graphical User Interface) for users and users who don’t have extra technical knowledge can also use it very well.
