Backups using LVM mirrored volumes
If you have EVS volumes configured on LVM mirrored volumes, you can back up the EVS volumes
on line, without disabling the EVS volume or interrupting access to the data.
To create LVM mirrored volumes, you must have the MirrorDisk/UX product installed. If you do
not have the MirrorDisk/UX product, you can backup an EVS volume to a spare EVS volume, or
you can back up an EVS volume to a tape or other non-EVFS device by disabling the EVS volume
and performing offline backups. For more information, see “Backups using nonmirrored volumes”
(page 94).
This section describes the following procedures:
• “Creating encrypted backup media on a Non-EVFS device (LVM mirrored volumes) ” (page 81).
• “Creating encrypted backup media on a second EVS volume using a block device utility (LVM
mirrored volumes)” (page 82).
• “Creating encrypted backup media on a second EVS volume using a file utility (LVM mirrored
volumes)” (page 84).
• “Creating cleartext backup media (LVM mirrored volumes)” (page 86).
