NDMP Backup Application Notes
Most NDMP backup applications work in a three-way configuration. A host computer
runs the backup application, one or more filers contain the data to be backed up, and
a tape server contains the tape library and device resource. All three of these
components must be present and must be able to communicate with each other over
the network. Whenever possible, all three components should be on the same subnet.
To configure most backup applications you must know about the devices attached to
the NDMP tape server. In the NDMP environment, the library devices are named as
below:
•Library:
Library0_0
•First Tape Device:
Tape1_0
•Second Tape Device:
Tape2_0
The backup application will also want to know the host name of the NDMP tape
server. This hostname is the name that was assigned in the Ethernet setup section of
this manual. The backup application will also need to know the user name and
password that it should use for the tape server device. This is the same user name and
password assigned to the library in
The recommended user name and password for this purpose is
root
.
Most backup applications will need the full pathname to the devices. The pathname
will be as follows (where the hostname is the name assigned in the Ethernet setup
section):
• <hostname>:Library0_0
• <hostname>:Tape1_0
• <hostname>:Tape2_0
For example:
spectra0:Library0_0
