A volume backup is a backup of an Exascale volume snapshot, which provides a consistent point-in-time copy of the volume.

The backup is stored in an Exascale vault, and the backup destination vault may differ from the vault containing the volume being backed up. Furthermore, Exascale automatically places file extents for volume backups on physically separate devices from the volume being backed up. This organization guarantees that if multiple failures affect a volume, its corresponding backups remain available.

You can restore a volume backup into a new volume. When you restore a volume backup, the restored volume is separate from the volume backup and the original backup source volume. There is no ongoing association between a restored volume and the volume backup or the original backup source volume.
