<h1 class="topictitle1">Save/Restore (SAV/RST) commands</h1>
<div><p>The SAV command can be used to create a backup of an optical volume
image. The volume image is restored using the RST command.</p>
<p> An optical volume image is a copy of the entire optical volume in *SAVRST
format. Using SAV, the volume image can be saved to any supported save/restore
device including tape, diskette, optical, or save file.</p>
<p>Subsequently, when the volume image is restored using the RST command,
the entire image must be restored to an existing optical volume either in
a stand-alone device or an optical media library.</p>
<p>An optical volume image has unique properties that require the entire volume
image to be saved or restored in a single operation. Once saved you cannot
restore individual files or directories.</p>
<p>Once an optical volume image is saved, it can be viewed with DSPTAP, DSPDKT,
DSPOPT, or DSPSAVF, depending on the save/restore device used. When the volume
save/restore entry is displayed, option 8 can be used to display the additional
information panel, which includes media specific information such as media
type, volume capacity, sector size, and security attribute information. You
cannot see the individual files and directories that make up the volume image.</p>
<p>Use of the generic SAV command to save optical data can be easily incorporated
into an existing system backup strategy without requiring a separate command
such as DUPOPT to perform the save operation. SAV provides a good alternative
to DUPOPT because it allows a volume to be saved from a one drive optical
media library or from a standalone device without requiring the allocation
of a second optical device. SAV provides a viable incremental backup solution
by periodically backing up volumes not yet at capacity to a save/restore device
such as tape. When the volume is full it can be duplicated for archival purposes
by either restoring the full volume to create a copy or by issuing DUPOPT
to duplicate the volume.</p>
<p>Saving and then restoring an optical volume image creates an exact copy
of the saved volume including the volume name. DUPOPT creates a copy of the
source volume but the volume name is changed.</p>
<div class="p">To save and restore an optical volume the following authority is required:<ul><li>*USE authority to the optical device.</li>
<li>*SAVSYS special authority OR *OBJEXIST authority through the optical volumes
authorization list.</li>
<li>If the media format is UDF *RWX authority is also required to the root
directory of the volume. The device will be locked shared (LSRD) read while
a SAV or RST is active.</li>
</ul>
