Client-Initiated Backups

NetWorker saves directories, files, or MPE volume sets in groups called save sets. The save

sets are saved to backup volumes on a NetWorker backup device. A NetWorker backup

volume is a unit of media used for backup, such as a magnetic tape, a disk, or an optical

disk. NetWorker stores and tracks your data on backup volumes on a regular basis.

MPE volumes are disks on an MPE client; MPE volume sets are sets of disks.

A NetWorker volume pool contains a collection of backup volumes to which specific

data has been backed up. Volume pools allow you to sort backup data to selected

volumes. For more information on managing media and backup devices, refer to the

Legato NetWorker Administrator’s Guide, UNIX Version.

Client-Initiated Backups

You can back up directories, files, groups of files, or MPE volume sets on an MPE client

from the MPE Command Interpreter (CI) or from the POSIX shell.

You enter the NSRSAVE command to start the NetWorker NSRSAVE program. The

NSRSAVE program is a client-side program that runs manual backups. Manual

backups are intended for quick backups of a few files or directories. They do not

generate bootstrap files or back up indexes, so they do not serve as replacements for

server-initiated backups.

For details on entering the NSRSAVE command to back up directories, files, groups of

files, or volume sets, see the following sections:

• “Backing Up a Directory” on page 17

• “Backing Up a File” on page 19

• “Backing Up a Group of Files” on page 19

• “Backing Up MPE Volume Sets” on page 20

Once you have backed up your data using either a server-initiated backup or a client-

initiated backup, you can recover any lost or damaged data by using the NetWorker

NSRRECOV program. See “Chapter 3: Recovering Files” on page 23 for information.

Setting System Variables for Client-Initiated Backups

You can set system variables in a CI session to affect client-initiated backups that you

perform from that specific session. Once you have set a system variable in a CI session,

then the setting affects all manual backups done during that session until you turn the

setting off in that CI session. You can perform backups from a CI session where the

system variables have not been set if you do not want them applied to specific backups.

Note that the system variables that you set do not affect server-initiated backups. The

system administrator can set these same variables for the scheduled backups done

from the NetWorker server. Similarly, system variables that are set for the server-

initiated backups do not affect your client-initiated backups.

The types of system variables that you can set for client-initiated backups include:

• Setting the NetWorker time zone to match the HP STORE program

• Creating logs of your NetWorker backups

• Storing temporary shadow logs of TurboSTORE online backups on a separate

MPE volume set

• Specifying a notification at the start or end of online backup

• Specifying the frequency for displaying the progress of backups
