NAME rsbackup-snapshot-hook - rsync-based backup utility SYNOPSIS rsbackup-snapshot-hook [OPTIONS] DESCRIPTION rsbackup-snapshot-hook creates and removes LVM snapshots when config- ured 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 vol- umes 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 snap- shot may be left in place (and ultimately be torn down when the post- volume-hook is run). OPTIONS --snaps, -s PATH Set the path to the snapshot directory. The default is /var/lib/rsbackup/snapshots. --divisor, -d DIVISOR Set the snapshot size ratio. The default is 5. --help, -h Display usage message. --version, -V Display version string. SEE ALSO rsbackup(1), lvm(8) AUTHOR Richard Kettlewell <rjk@greenend.org.uk>
