Hi, i have several servers running different Linux distributions. Our computing center provides a network-based backup solution (Legato/EMC), which saves the disks every night. But when the servers run, this backup is of course not consistent. The servers are running a lvm configuration (/ on lv and /boot on a physical partition). My idea is to create a snapshot and mount it before the network backup comes. When this is stored, my backup is consistent. I can configure the networker client in such a manner that the "live" lv is not saved, just the snapshot so that the server is not saved twice. My questions: Before I create a new snapshot, I'd like to remove the old one. Is there something I have to take care of or can I just delete it using lvremove ? No merging or s.th. like that before ? What is if I'd like to apply the snapshot ? Which command do I have to use for rolling back the system to a snapshot ? Thanks.
