NAME¶
rsbackup-snapshot-hook - rsync-based backup utility
SYNOPSIS¶
rsbackup-snapshot-hook [
OPTIONS]
DESCRIPTION¶
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
/snap/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).

- --divisor, -d DIVISOR
