This thread has piqued my interest, because I have been lax in doing proper backups. I currently run a RAID1 mirroring across three disks (plus a hot spare). On top of that is LUKS, and on top of that is LVM. I keep meaning to manually fail a disk then store it in a safe deposit box or something as a backup, but I have not gotten around to it. It sounds to me like adding an iSCSI volume (e.g. from AWS) to the RAID as an additional mirror would be a way to produce the off-site backup I want (and LUKS means I am not concerned about encryption in transit). It also sounds like you're saying this is not a good backup approach. Ignoring cost, what am I missing? > Reco --Gregory
