Backing up and restoring a file system

To back up a VxFS file system, you first create a read-only snapshot file system, then back up the snapshot. This procedure lets you keep the main file system on line. The snapshot is a copy of the snapped file system that is frozen at the moment the snapshot is created.

See About snapshot file systems.

See the mount_vxfs(1M), vxdump(1M), vxrestore(1M), and mount(8) manual pages.
