New backup function

[Diablo_Vmax1200]

Hi!

Wouldn't it be nice to have the possibility to roll back over some days / weeks / months?
The size of the backup wouldn't be extremely high if resync is used. A nice description can be found here: http://linuxwiki.de/rsync/SnapshotBackups (only in german)
Resync doesn't support diff backup and compression so flexbackup or amanda mybe would be nicer to keep the volume more tiny.
But I don't know how long a backup would take and how much performace will be consumed.
