NDMP Local Library
Backup
In an NDMP local library configuration, as shown below, the tape
drives and the library changer device in a tape library are connected
to SCSI HBAs in the IP4700 system. The backup server controls the
library changer device attached to the IP4700 via a SCSI pass-through
function in the IP4700 system. IP4700 backup data flows from the
IP4700 system directly to the tape drive. Via the LAN, the backup
server uses NDMP to instruct the IP4700 system to perform the
backup. The backup server can also back up LAN clients. The backup
server still manages the index, or catalog data.
