Creating mirror break-off snapshots for volumes

Last published : Jun 19, 2026
The Management Server console lets you configure mirror break-off snapshots. The mirror break-off snapshot is created when one or more mirrored disks in a volume is detached and retained as a different volume. You can create a mirror break-off snapshot for a volume only if the volume is snap-ready mirror.
The operation is not supported on Windows host.
To perform this task, your user group must be assigned the Admin role on the host or the Server perspective. The permission on the host may be explicitly assigned or inherited from a parent Organization.
