Configuring Your IP4700 Device for Use with Backup Software

Backup Configurations

NDMP Three-Way

Backup

In an NDMP three-way backup configuration, a backup server directs

one IP4700 system, without a local tape drive, to send NDMP data

over the network to another IP4700 system with a local tape drive.

NAS backup data flows from the primary IP4700 system, which is the

device attached to the tape drive, directly to the tape drive. NAS

backup data from the second IP4700 system flows, under NDMP

control by the backup server, across the LAN to the primary IP4700

system, then to the tape drive. The backup server can back up LAN

clients as well. The backup server still manages and stores the index,

or catalog data.

In this configuration you can use a stand-alone tape drive instead of a

library drive. Also, note that within one IP4700 system, one SP can be

the primary IP4700 system, and the other can be the second IP4700

system. This means that SP A could do the backup for SP B, using the

mechanism described above. The following diagram shows the

NDMP three-way backup configuration.
