Oracle Linux KVM - VMs backup

in Oracle VM (OVM) (MOSC) 2 commentsAnswered

Hi,

In the context of iSCSI Storage (i.e VM disks as LVM partitions if I understood well) what is the proposed / preferred solution to backups all LVM partitions, as part of a Disaster Recovery Plan ?

Currently we're on Oracle VM. VM disks are files. We're relying on the Storage Array Snapshots :

We mount a Volume Snapshot into a dedicated Machine w/ ocfs2 stack configured (weekly). Because the snapshot was taken live, we run tunefs.ocfs2 , fsck.ocfs2. Then we tar all the files to tape. Then store tapes in a safe.

Offline, out-of-band full backup.

Even though this is done live and not quiesced, I can say that we never encountered a problem when doing our monthly restore test. Restored VM start like if they crashed, but 100% of the time it went well.Of course data (database, user files) have also a separate backup plan.

Howdy, Stranger!
