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 NAStape 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 NAStape device is named as
Tape1_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 NAStape in
The recommended user name and password for this purpose is
root
.
Most backup applications will need the full pathname to the device. The pathname will
be
<hostname>:Tape1_0
, where the hostname is the name assigned in the Ethernet
setup section; for example:
spectra0:Tape1_0
.
Network Appliance Filer Setup
The filer will need some setup in order to interact with the NDMP agent. Since data
will flow to the NAStape on a backup, there are steps that are required to authorize
access to the data on the filer.
First, the filer must recognize the NAStape by its hostname. This is accomplished by
adding an entry to the
/vol/vol0/etc/hosts
file on the filer. The format is the
same as the hosts file on the backup host; for example:
10.0.0.254 spectra0
.
Verify that the filer can successfully ping each NAStape to which it will be backing up;
for example:
ping spectra0
.
