USB-Backup

USB-Backup is a free backup solution for creating encrypted backups to external USB media.

For the compression and the backup format itself the proven and very stable software 7-Zip is used.

Features

  • local disks, such as the system disk C: can be backed up by using shadow copies (warning, this requires administrator privileges)
  • the use of the program is user-friendly and has been developed in cooperation with users
  • Network drives and UNC paths can also be backed up
  • Installation: no setup, just one AutoIT script (put together into one executable)
  • Security:
    • during the initial backup, a password is set - without a password, you can not back up!
    • when the external disk will be lost, a stranger can not really see what was backed up
    • only username@pc are stored plaintext, but this is used to distinguish the backups in case of emergency
    • an encrypted index is stored on the external disk, so that a restore at any time and on any computer is possible
  • to each directory, you can create exception lists
  • after a setable time, USB-Backup reminds the user to update the existing backup
  • the degree of compression and other 7-Zip parameters can be completely adapted in the USB Backup.ini
  • Automatic updates of program and help file are possible, but you can disable this also
  • the help file is currently not finished, sorry about that :(
    • you can help me with that :)
