       rsbackup-snapshot-hook - rsync-based backup utility


       rsbackup-snapshot-hook [OPTIONS]


       rsbackup-snapshot-hook  creates  and  removes  LVM  snapshots when configured as a pre- or
       post-backup-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-backup-hook is run).


       --snaps, -s PATH
              Set    the    path    to    the    snapshot    directory.     The    default     is

       --divisor, -d DIVISOR
              Set the snapshot size ratio.  The default is 5.

       --help, -h
              Display usage message.

       --version, -V
              Display version string.
