USB-Backup is a free Graphical user interface for creating encrypted backups to external media. It is distributed under the GPLv2-License.
For the compression and the backup format itself the proven and very good compressing Open Source Software 7-Zip is used.
The assurance is based on the so-called differential backup. In this method, the first backup is a "full backup" of the desired data is then updated only by updates. This way, only the first backup is time consuming and each additional update goes quite quickly. Furthermore, one can quickly restore all the data again in case of emergency.
- local disks, such as the system disk C: can be backed up by using shadow copies, but this requires administrator privileges
- the use of the program is user-friendly and has been developed in cooperation with users
- Network drives can also be backed up
- Installation:
- the program does not require installation - so it is also admin-friendly ;)
- I put it mostly in the Startup folder of the corresponding user and thats it
- the configuration can be found in this folder: %APPDATA%\USB-Backup
- diverting temporary data will be stored in this folder: %TEMP%\USB-Backup_%TEMPID%
- 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 that are then passed to 7-Zip
- 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 to 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... but will come later...
