Restoring Solaris Zettabyte (ZFS) file systems

Zettabyte File Systems (ZFS) use storage pools to manage physical storage.

You can back up and restore ZFS snapshots in one of the following ways:

1. Back up and restore each file of the snapshot by using the snapshotroot option. This option allows the administrator to replace the current snapshot path with the ZFS file system path.

   Using the snapshotroot option, the files can be directly restored in the file system. If you have many changes in the file system during a backup, a snapshot could be made first, and then the Tivoli® Storage Manager Backup-Archive Client can make a backup of the static snapshot.

2. Another way is to back up and restore the complete snapshot. The administrator can then make a copy of the complete snapshot data in a single file, and this file can be backed up and restored by the Tivoli Storage Manager Backup-Archive Client to the Tivoli Storage Manager Server.

   The advantage of backing up and restoring the complete snapshot is that the full file system can be restored in a disaster recovery case.
