This is an installation on Red Hat 5.2 and 5.5 (same procedure). Note that the installation of the NetBackup 7 client is only supported on 64 bits systems.

Preparing for the installation is equal to NetBackup Solaris Client.

The installation is also started the same way:

[root@redhatbox NetBackup_7.5_CLIENTS]# ./install

If you get this error:

cp: preserving permissions for `/usr/openv/pack/NB_CLT_7.5.0.4/save/NB_update.uninstall': Operation not supported
cp: preserving ACL for `/usr/openv/pack/NB_CLT_7.5.0.4/save/NB_update.uninstall': Operation not supported

You're probably running the installation from a NFS mount which supports more permissions than the Red Hat server does. See also this discussion on the subject.

This can be recognized by the + signs at the end of the permission column:

Your solution is to copy the installation source to a local filesystem or if you can't do that, to disable the advanced permissions on the NFS share.

The install takes up a lot of temporary space, so you could run out of disk space. You can mount a NFS datastore in the client and pack directory to save space:

root@redhatbox:/usr/openv/netbackup# mount -t nfs nfsbox:/home/sjoerd/temp /usr/openv/netbackup/client/ -o rw
root@redhatbox:/usr/openv/netbackup# mount -t nfs nfsbox:/home/sjoerd/temp /usr/openv/pack/ -o rw
