About VxFS_Snapshot
The VxFS_Snapshot method is for making copy-on-write snapshots of local Solaris or HP clients. Off-host backup is not supported with this snapshot method.
Note the following:
VxFS_Snapshot supports the FlashBackup policy type only.
The VxFS_Snapshot method can only be used to back up a single file system. If multiple file systems are specified in the policy's list when you use this method, the backup fails.
In a FlashBackup policy, if the list contains CACHE= entries, FlashBackup does support the backup of multiple file systems from a single policy. For each file system, a separate cache must be designated with the CACHE= entry. Make sure you create a separate policy for each file system.
See Configuring FlashBackup policy for backward compatibility (UNIX only).
You must designate a raw partition to be used for copy-on-write cache.
Raw partition example:
Solaris:
/dev/rdsk/c1t0d0s3
Or
/dev/dsk/c1t0d0s3
HP:
/dev/rdsk/c1t0d0
Or
/dev/dsk/c1t0d0
See Cache device requirements.
See Entering the cache.
VxFS_Snapshot is the default snapshot method for FlashBackup clients running HP, when is not selected for the backup policy.
