ssbackup-batch - a tool for calling ssbackup
This manual page explains the ssbackup-batch tool. This tool
is a frontend to ssbackup(8), an implementation of the snapshot-style-backup
method that is described in http://www.mikerubel.org/computers/rsync_snapshots/.
config-file is a configuration file that contains rules for making backups
Typically config-files (and exclude-files) are put into /etc/ssbackup/.
and ssbackup-batch is executed daily by a crontab-entry like:
12 4 * * * /usr/sbin/ssbackup-batch /etc/ssbackup/config
or by a script in /etc/cron.daily/ like:
which also works with anacron.
A config file describes one or more recipes for backups. To
understand the nomenclature please see ssbackup(8).
- shows the version-number of
ssbackup-batch and exits
- -h, --help
- shows a short help explaining the options
- -v --print-plan
- Print only a plan what would have been done, but do nothing
- -o, --check-only
- pass the --check-only flag to ssbackup. (please there

a backup-recipe consists of a line starting with backup

only and have no global effect. name is the name of the backups. Indented
lines can be:
- source =
- specifies the source to back-up. There must be
a source in a recipe
- basedir =
- specifies the basedir, where the backups
go. If given in a recipe as indented line it overwrites a global basedir
- count =
- specifies the count (number of versions). If given
in a recipe as indented line it overwrites a global count temporarily.
- specifies the exclude-file for rsync.
In a recipe everey kind of indented
line can occur one time. If a indented line is given more than once the
last one wins. It is not possible to give p.e. several exclude-files.
for a config-file.
basedir = /backup
count = 24
# Home Directory
source = nfs://milkyway:/export/home/1
exclude = /etc/ssbackup/home.exclude
source = nfs://milkyway:/export/var/mail
source = file:///scratch/project-data
basedir = /data-backup
count = 12
ssbackup can easily destroy valuable data if called with wrong
parameters, especially if called as root. So think twice bevor calling it,
especially if you do it automatically via ssbackup-batch.
