<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>
|
||
|
|
Auditing records created during a SAV or RST request. <ul><li><strong>OR</strong> Object Restored</li>
|
||
|
|
<li><strong>RZ</strong> Change primary group during restore. Saved value different from
