The snapshot needs to go somewhere where there is free space available.

I want to make backups of VMs residing within LVM logical volumes. IIUC, making a snapshot of a LV would allow me to somehow make a copy of the snapshot which I can store elsewhere as a file so that I can restore from that without shutting down the VM. However, I could shut down the VM to make a backup. So either way, what's the best way to make a backup? When I can't even make snapshots as I see fit, what's the point of LVM?? -- Hallowed are the Debians! -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
