Specifies the partition on which the volume resides. Provide the
B<-server> argument along with this one.
+=item B<-clone>
+
+Normally, B<vos dump> locks the volume and dumps it, which blocks writes
+to the volume while the dump is in progress. If this flag is given, B<vos
+dump> will instead clone the volume first (similar to what B<vos move>
+would do) and then dumps the clone. This can significantly decrease the
+amount of time the volume is kept locked for dumps of large volumes.
+
+=item B<-omitdirs>
+
+By default, B<vos dump> includes all directory objects in an incremental
+dump whether they've been changed or not. If this option is given,
+unchanged directories will be omitted. This will reduce the size of the
+dump and not cause problems if the incremental is restored, as expected,
+on top of a volume containing the correct directory structure (such as one
+created by restoring previous full and incremental dumps).
+
=item B<-cell> <I<cell name>
Names the cell in which to run the command. Do not combine this argument
