About VxFS_Checkpoint

The VxFS_Checkpoint snapshot method is for making copy-on-write snapshots. This method is one of several snapshot methods that support Instant Recovery backups. Note that for VxFS_Checkpoint, the Instant Recovery snapshot is made on the same disk file system that contains the client's original data.

For VxFS_Checkpoint, VxFS 3.4 or later with the Storage Checkpoints feature must be installed on the NetBackup clients. HP requires VxFS 3.5; AIX and Linux require VxFS 4.0.

Note:

On the Red Hat Linux 4 platform, VxFS_Checkpoint snapshot method supports Storage Foundation 5.0 MP3 RP3 HF9 or later versions.

Note the following:

The VxFS_Checkpoint method is not supported for backing up raw partitions (whether FlashBackup or Standard policies).
Make sure that enough disk space is available for the checkpoint. The file system containing the snapshot source should have at least 10% free space to successfully implement the checkpoint.
