rsbackup-snapshot-hook  creates  and  removes LVM snapshots when configured as a pre- or post-volume-hook
       for rsbackup(1).

       Snapshots will only be created for volumes that have a corresponding directory in the snapshot directory.
       For instance, a snapshot will be created for the volume root if /var/lib/rsbackup/snapshots/root  exists.
       (Use  the  --snaps  option  to  change the snapshot directory.)  Such volumes must be stored in a logical
       volume.

       Leftover snapshots are always unmounted and removed before creation.

       Snapshots are given only a fraction of the size of the original volume.   Use  the  --divisor  to  change
       this.

       After creation snapshots are fsck'd and mounted.  If an error occurs in any part of the creation process,
       the  partially snapshot created snapshot may be left in place (and ultimately be torn down when the post-
       volume-hook is run).
