I must have done something wrong because for the past week or so, almost none of my questions have been answered here. I'm pretty much in trouble now because I have -no- backups, as I cannot get my backup server running, as I've put all my eggs in the btrfs basket. Am I asking things wrong, or am I supposed to be asking somewhere else? On Thu 20 January 2011 13:18:40 Carl Cook wrote: > > Well I've just tried to add a disk to another, but it fails.

Tentatively I've created a BTRFS volume and mounted it on /media/backups. I then created subvolumes as backup-hex, backup-droog, snaps-hex and snaps-droog. When I created a snapshot it created a subdir under snaps-hex called hex-root. > > It won't allow me to remove snapshots.
