Configuring Your IP4700 Device for Use with Backup Software
Backup Configurations
Non-NDMP NFS or
CIFS-Specific
Private LAN
A non-NDMP NFS or CIFS-specific private LAN configuration, also
called IP4700 network drive backup, is available only with
NetBackup. It is similar to a standard private LAN backup in that the
backup server communicates with the client computer systems to
control the backup. The main difference is that the client systems
must first retrieve their backup data from the IP4700 system, and then
retransmit this data to the backup server. The backup server then
sends the data to the tape library. This method retains only the file
system attributes that the backup client uses. Therefore, if NFS and
CIFS clients usually access the backup data and the NFS client is used
for backup, the UNIX® and CIFS attributes are lost on the backed up
copy.
During system configuration, for best performance we recommend
that you set up the mount points and file shares so that backup data
flows across the private LAN. The non-NDMP NFS or CIFS-specific
private LAN configuration is shown below.
