<para>This application is not yet in its final form, and is subject to major revision
in subsequent versions of Amanda. Backward compatibility is not guaranteed.</para>
-<para>The significant limitations of this version of amvault are: tapetypes for
-secondary and tertiary volumes much match (including length and
-device_properties); tertiary volumes must be blank (manual erasure is required
-to re-use tertiary media; restore/recover operations will request tertiary
-media by label when dumpfiles are not found on secondary media, but there is no
-provision to automatically fetch such media from a different changer; and all
-dumpfiles on a secondary volume are moved to tertiary media - there is no
-provision to filter dumps.</para>
+<para>Note that Amanda restore/recover operations will request tertiary media

<para>Feedback on and patches to this application are invited and
encouraged!</para>
<refsect1><title>DESCRIPTION</title>
+<para>Amvault is conceptually equivalent to "amfetchdump | taper". That is, it reads
+specified dumps from secondary media and re-writes them on tertiary media.</para>
+
<para><emphasis remap='B'>Amvault</emphasis> Copies data from the run with
-timestamp <emphasis remap='I'>src-run-timestamp</emphasis> onto volumes using
-the changer <emphasis remap='I'>dst-changer</emphasis>, labeling new volumes
-with <emphasis remap='I'>label-template</emphasis>. If <emphasis
-remap='I'>src-run-timestamp</emphasis> is "latest", then the most recent amdump
-or amflush run will be used.</para>
+timestamp <option>src-timestamp</option> onto volumes using the changer
+<option>dst-changer</option>, and labeling new volumes with
+<option>label-template</option>. If <option>src-timestamp</option> is
+"latest", then the most recent amdump or amflush run will be used. If
+<option>--fulls-only</option> is given, then only full (level-0) dumps are
+copied.</para>
+
+<para>The <option>--quiet</option> (<option>-q</option>) option will
+eliminate non-error messages, and is useful when running amvault from
+cron. The <option>--dry-run</option> (<option>-n</option>) option will
+cause amvault to print the dumps it would vault, but not actually perform
+any vaulting operations.</para>
+
+<refsect2><title>Secondary Media</title>
+
+<para>The dumps to be read from secondary media can be specified by any
+combination of dump specifications, <option>--fulls-only</option>, and
+<option>--src-timestamp</option>. At least one must be specified, lest
+amvault attempt to vault all dumps in the catalog. See <manref
+ name="amanda-match" vol="7"/> for more information on dump
+specifications.</para>
+
+<para>Note that the datestamp given in the dumpspec is the
+<emphasis>dump</emphasis> datestamp - the run in which the backup was taken
+on the Amanda client. The <option>--src-timestamp</option>, on the other
+hand, is the <emphasis>write</emphasis> timestamp - the run in which the
+dump was written to secondary media. The latter option facilitates
+duplicating the results of an entire backup run, including any dumps that
+might have been flushed from holding disk.</para>
-<para>In a vaulting operation, the source media is referred to as "secondary
-media", while the destination is referred to as "tertiary media".</para>
+</refsect2>
-<para>Each source volume will be copied to a new destination volume; no
-re-assembly or splitting will be performed. Destination volumes must be at
-least as large as the source volumes.</para>
+<refsect2><title>Tertiary Media</title>
+
+<para>The <option>--dst-changer</option> must be specified, and names the changer
+in which tertiary media are stored. In general, this should be different
+from the secondary changer, to eliminate the possibility of overwriting
+secondary media with tertiary data.</para>
<para>The changer parameter should specify the name of a changer defined in
&amconf;. For example:
}
</programlisting></para>
-<para>The <emphasis>--quiet</emphasis> option reduces the verbosity of the
-utility; this can be useful for volumes containing many split parts. The
-<emphasis>--autolabel</emphasis> option defines which tertiary volumes
-amlabel will overwrite. It can have any of the values defined for
-<amkeyword>autolabel</amkeyword> in <manref name="amanda.conf" vol="5" />,
-with the addition of "this_config", meaning volumes matching the labelstr
-for this configuration. The option defaults to "empty". Multiple
-values can be separated with commas. The label template functions
-identically to the template for teh <amkeyword>autolabel</amkeyword>
-parameter.</para>
+<para>The <option>--label-template</option> option is required, and specifies a
+label template which is used to generate new labels for tertiary volumes.
+The <option>--autolabel</option> option works just like the
+<amkeyword>autolabel</amkeyword> parameter in &amconf;, and can be
+specified multiple times if necessary. The default is 'empty'.</para>
+
+<para>If &amconf; contains the new <amkeyword>part-size</amkeyword>
+splitting parameters, then amvault will use them without any additional configuration.
+However, if the configuration still uses the old splitting parameters
+(<amkeyword>tape_splitsize</amkeyword>,
+<amkeyword>split_diskbuffer</amkeyword>, and
+<amkeyword>fallback_splitsize</amkeyword>), then amvault will need some
+additional configuration in order to properly split dumps to tertiary
+media. To do so, specify a new tapetype in &amconf;, say "TERTIARY",
+and set the <amkeyword>part-size</amkeyword> and other appropriate
+parameters there. Then reference that tapetype in the amvault invocation:
+<programlisting>
+ amvault -otapetype=TERTIARY ...
+</programlisting></para>
+
+<para>The <option>--export</option> option will cause amvault to attempt to move
+completed tertiary volumes to import/export slots, where they can be
+more easily removed by an operator.</para>
