February 3, 2003 EMC CLARiiON Open Systems Configuration Guide Local Disk Backup with Remote Archive This topology uses disk-to-disk backups at the production site, as well as a remote tape library upstream at a regional or central data center. This upstream site is reached via a narrow WAN IP circuit, possibly using DSL or broadband cable. Data is backed up to disk at the local site. Data is restored rapidly from the same local site disk. In the event of a local site disaster or data corruption, data can be restored from the remote archive. Some or all of the backup data is archived from the local site backup media to a remote location, reducing IT costs while providing centralized management. This topology does not use local tape drives. Distance are not limited and low speed links can be utilized. This topology is useful in a remote branch office environment.

Local Disk Backup with Remote Archive
This topology uses disk-to-disk backups at the production site, as well as a remote tape library upstream at a regional
or central data center. This upstream site is reached via a narrow WAN IP circuit, possibly using DSL or broadband
cable.
Data is backed up to disk at the local site. Data is restored rapidly from the same local site disk. In the event of a local
site disaster or data corruption, data can be restored from the remote archive. Some or all of the backup data is
archived from the local site backup media to a remote location, reducing IT costs while providing centralized
management. This topology does not use local tape drives. Distance are not limited and low speed links can be
utilized. This topology is useful in a remote branch office environment.
