Questions and answers

  • What is a ".FBU backup" file and how is it created?

    A ".FBU backup" file is a backup file created by the application called FreeFileSync. FreeFileSync is a free and open-source file synchronization and backup software.

    To create a ".FBU backup" file using FreeFileSync, you need to follow these steps:

    1. Download and install FreeFileSync on your computer.
    2. Launch FreeFileSync and set up a synchronization or backup task.
    3. Select the source folder or files that you want to back up.
    4. Choose the destination folder where you want to store the backup.
    5. Configure any additional settings or filters you require.
    6. Click on the "Synchronize" or "Backup" button to start the process.
    7. FreeFileSync will compare the source and destination files and copy any changes or new files to the backup location.
    8. Once the synchronization or backup is complete, FreeFileSync will generate a ".FBU backup" file, which contains information about the backup task and the files that were backed up.

    The ".FBU backup" file can be used later to restore the backup or to perform incremental backups by comparing it with the source files.
