Client-Initiated Backups

Backing up files is short-term insurance against data loss. The NetWorker
server to which your HP 3000 is a client automatically backs up your files
according to a backup schedule determined by your system administrator.
For an overview on how to perform manual backups of directories, files, or
volume sets on an as-needed basis from your HP 3000, see “Client-Initiated
Backups” (on page 18).
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.
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
if you prefer.
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.
See “Backing Up a Directory” (on page 20), “Backing Up a File” (on page 22),
“Backing Up a Group of Files” (on page 23), and “Backing Up MPE Volume
Sets” (on page 23) for details on entering the NSRSAVE command to back up
directories, files, groups of files, or volume sets.
Once you have backed up your data by either a server-initiated backup or a
client-initiated backup, you can recover any lost or damaged data by using the
NetWorker NSRRECOV program. “Chapter 3: Recovering Files” (on page 27)
for information on recovering files.
