Overview of JFS2 snapshots
The snapshot functionality was provided to create consistent and integrated snapshots of an online or offline JFS2 filesystem. A point-in-time copy of the source file system is created. The snapshot operation executes quickly and requires very little disk space. Multiple snapshots can be taken.
The snapshot retains the same permissions as the original file system. Once the image has been created, you can use it to restore files or an entire file system to a known point in time. Or, you can mount the snapped file system and perform a backup of it to tape. This could help reduce your backup time requirements.
