Method 1: Inbuilt Backup Tool of Microsoft

If you are a user of Microsoft Windows then you already have in-built software for the backup of all the data in windows called NTBackup.

NTBackup is the built-in backup application in Windows to create a proprietary backup format (BKF) (also known as “Microsoft Tape Format” or MTF) to back up files. With this tool, you can back up your data in the Zip Drives, Floppy Disk, and Hard Drives. It supports –

  • Encrypting File System.
  • NTFS hard links and junction points.
  • Alternate data streams.
  • Disk quota information.
  • Mounted drive and remote storage information.
  • Saves New Technology File System (NTFS) permissions.
  • Respects the archive bit attribute on files and folders.
  • Audit entries and ownership settings.
  • Can create differential and incremental backups.
  • Backup catalogs, as well as Automated System Recovery.

Part 1: Restore Catalog file

Follow these steps to create a catalog file and restore the backup database.

  • On the Restore tab of NTBackup.exe utility,> right-click on File > click Catalog file.
  • Place the correct media or backup file (.bkf file), and then click OK.

Part 2: Recreate New Catalog file

Remove all the catalogs files from the restore tab and recreate new catalog file, for the backup which you want to restore.

  • Open Restore tab and right-click on each catalog to delete catalog file from Restore tab.
  • On the Restore tab, right-click File > click Catalog file.
  • Place the correct media or backup file (.bkf file) > click OK.
  • Repeat this process for each catalog files, if you are performing multiple restores at the same time.

But the problem is that NTBackup tool is also not fault-proof as it also gets corrupt due to some unavoidable reasons such as virus, improper system shutdown, power failure, etc. Sometimes, NTBackup corruption happens due to missing catalog backup files. In such situations, you may not be able to use the BKF file to restore your data at the time of data loss.
