Rsnapshot is great:Other than tar and rsync, I have never used any Linux backup utilities, and I am looking for recommendations. I would like an open source solution which will do the following: 1. Back up to removable hard drives 2. Span multiple target volumes 3. Maintain a virtual fileysystem so all snapshots look like a single backup to the user. 4. Maintain an easily monitored index so the user can see which drive will be needed for a particular backup or restore operation. 5. Be able to easily rebuild the index and virtual file system from the backup drives (preferebly just one drive) if the database is lost on the source system.
