About VxVM
The snapshot method is for making mirror snapshots with Veritas Volume Manager 3.1 or later snapshot mirrors. (On Windows, make sure that VxVM has the latest VxVM service packs and updates.)
Note:
On the Red Hat Linux 4 platform, VxVM snapshot method supports Storage Foundation 5.0 MP3 RP3 HF9 or later versions.
The snapshot method works for any file system that is mounted on a VxVM volume. However, before the backup is performed, the data must be configured with either of the following: a VxVM 3.1 or later snapshot mirror or a VxVM 4.0 or later cache object. Otherwise, the backup fails.
Note the following:
See Creating a snapshot mirror of the source.
Or refer to your Veritas Volume Manager documentation.
Help is available for configuring a cache object.
See About VxVM instant snapshots.
Or refer to your Veritas Volume Manager documentation.
For Instant Recovery backups of the data that is configured on VxVM volumes on Windows, the VxVM volume names must be 12 characters or fewer. Otherwise, the backup fails.
VxVM and VxFS_Checkpoint are the only snapshot methods in Snapshot Manager that support the multi-volume file system (MVS) feature of VxFS 4.0.
Since VxVM does not support fast mirror resynchronization on RAID 5 volumes, must not be used with VxVM volumes configured as RAID 5. If the snapshot method is selected for a RAID 5 volume, the backup fails.
