Hi,
I'm a pretty new user of Openfiler and I'm wondering myself what is the
best way to achieve iSCSI backup.
Indeed, I'm using iSCSI volume to export Xen block devices over network.
Each of my Xen DomU have its own iSCSI volume. On my Openfiler box I
have a LTO-3 tape drive and I want to make backup and recovery as simple
as possible.
I'm thinking about this procedure :
- make a LVM snapshot of my iSCSI volume
- dd the snapshot to a backup file (may be is it possible to pipe it
directly to the tape drive?)
- send the backup to the tape drive
- delete the LVM snapshot
And in case of disaster I should have only to restore LVM metadata and
write backup to LVM volume using dd.
What do you think about this usage? Am I wrong somewhere? May be I
missed something?
