Client Software Installation Requirements

You must have at least 50 Mbytes of free space in your /var/tmp filesystem to perform the Backup installation. In addition, the file index requires 220 bytes for each file and version per client. Lastly, the media index requires approximately 60 Mbytes of free space.

To request backup and recovery services from the Backup server, Backup clients must be able to access the Backup software. There are two ways a client can access the Backup software:

• Clients can have an NFS-mounted directory on the remote system where the Backup programs are located.

• Clients can have the Backup programs installed directly on their local disks.

The PATH environment variable for the user root on the Backup server and the user on each Backup client must contain the directory (usually /usr/sbin/nsr and /usr/bin/nsr) where the Backup executables reside.

If you have clients of the same hardware platform as the Backup server, use the same software to install Backup on the clients. For clients with different hardware platforms, you need to purchase and install the required client software for that platform separately. Contact Sun or your Authorized Sun Reseller for more information.

When the pkgadd command script asks you to select a package to install, enter 1 for the client software. Optionally, you can enter 2 to install the SUNWsbum package at the same time. Do not press the [Return] key for the default response all. If you purchased support for storage nodes, you can install the SUNWsbun package at the same time, as long as the SUNWsbuc package is the first package selected for installation.

The SUNWsbuc package temporarily requires 15 MB of free space on the client machine.

To back up a Backup client over the network, the nsrexecd daemon must be active on the client. The pkgadd installation program automatically starts nsrexecd after a successful installation session.
