RE: 10 outstanding Linux backup utilities
Try Microlite Backup Edge. Can create bare metal disaster recovery backups to tape or DVD that can be restored to new hard drive(s) - not simply file backup/restore. When paired with HP Proliant servers, can boot from the disaster recovery media and restore entire system simply (OBDR). Been using it for years with SCO Openserver 5, Caldera, SLES9, and SLES10.
