Hi, In your opinion, does it make sense to be able to create non-persistent snapshots ? In the case of a filesystem backup, a non-persistent snapshot would be a snapshot that we agree to lose in case of failure or reboot. If anything happens, a server administrator would have to recreate a new snapshot and then restart the backup. In this case, I think metadata could be stored in memory instead of on disk, which should improve LVM snapshot performance. Is this theory wrong, and is this something which can be implemented easily in the current LVM code ?
