A software product designed to provide online snapshot backup and restores of Microsoft SQL Server 2000 databases on the IBM TotalStorage Enterprise Storage Server (ESS).

Total Storage Enterprise Storage Server -
also called the "Shark" - the predecessor of the IBM DS8000 series - IBM' s biggest Enterprise Storage machine before the DS8000's arrived.
PPRC
"Peer to Peer Remore Copy" -
IBM's implementation of replication services for storage volumes to another control unit in a remote site.
Synchronous PPRC causes each write to the primary volume to be performed to the secondary as well, and the I/O is only considered complete when update to both primary and secondary have completed.
Asynchronous PPRC will flag tracks on the primary to be duplicated to the secondary when time permits.
