The File Backup module

  • Regular backup of user's files for PCs under GNU/Linux, Windows and Unix,
  • no software set up on the client,
  • optimization of the space used on the server by never storing twice a file,
  • web administration interface integrated in webmin and LRS control panel,
  • recovery of backed up files through a web interface,
  • backup on hard disk, thus, speed of data recovery.

The optimal solution to manage backups and recovery quickly, easily and carefree.

Quoting Eric Vuillermet, system administrator of "Les Cristalleries de Saint-Louis", eldest company in France created in 1648 : "When I walk in the corridors, users kiss my hands."

1. User interface

The file Backup module is administrated through a web interface that allows :

  • to consult the list of PCs whose backup is managed by the module,
  • to see the state of the backed up PCs,
  • to access to previous backups and to recover files,
  • to consult global or individual logs of the backup,
  • to launch a manual backup,
  • to restore one or several directories, one or several files, either directly in their original location or by getting back an archives or a zip file,
  • to graphically configure the directories or shares that you wish to backup.

2. Design

The directories that need to be backed up must be shared (Windows), exported via NFS (Unix/Linux) or reachable through ssh/rsync, or ssh. The LRS will regularily scan the directories and compare the files with the one stored. This comparison is made by working out a signature for each file and by comparing it to previously stored file signatures. File names are thus not important. If files have appeared or were modified, they'll be backed up on the server and included in the spool of available files. The file backup module of the LRS is based on BackupPC http://backuppc.sourceforge.net , a free software developed on sourceforge.net by an international team of programmers under direction of Craig Barratt. Linbox FAS contributed various patch to the software as well as the internationalization (i18n) and the first french translation.
