<h1>rsbackup and Debian</h1>
<p>The Debian package of <code>rsbackup</code> has some extra
features. You could use these on other systems but on Debian they
are set up to work automatically.</p>
<h2><code>/etc/rsbackup/config</code></h2>
<p>In the <code>.deb</code> package, the default
<code>/etc/rsbackup/config</code> is as follows:</p>
<pre class=example># Location of lockfile
lock /var/run/rsbackup.lock
# User configuration
include /etc/rsbackup/local
# Hosts
include /etc/rsbackup/hosts.d</pre>
<p>Normally you would not edit this file. Instead, put local
configuration in <code>/etc/rsbackup/local</code> and a file for
each host to back up into <code>/etc/rsbackup/hosts.d</code>.</p>
<h2><code>/etc/rsbackup/defaults</code></h2>
<p>There is an extra configuration file for the cron jobs,
<code>/etc/rsbackup/defaults</code>. The default is as
follows:</p>
<pre class=example>#
# Set backup=hourly|daily|weekly|monthly to control frequency of
# backup attempts. (Use backup policies for fine-grained control over
# when backups happen.)
#
backup=hourly
#
# Set report=hourly|daily|weekly|monthly to control frequency of
# email reports. (Hourly is probably a bit much!) Only effective
# if email is not "".
#
report=daily
#
# Set email=ADDRESS to have the report emailed to that address.
#
email=root
#
# Set prune=hourly|daily|weekly|monthly|never to control frequency of
# automated pruning of old backups
#
prune=daily
#
# Set prune_incomplete=hourly|daily|weekly|monthly|never to control
# frequency of automated pruning of incomplete backups
#
prune_incomplete=weekly
#
# Prefix to the rsbackup command
# Use 'nice' and/or 'ionice' here
#
nicely=</pre>
<ul>
<li>
<p>Set <code>backup</code> to control the frequency of backup
attempts. Normally this can be left at <code>hourly</code> and
the frequency of each host and volume’s backups controlled via
backup policies.</p>
</li>
<li>
<p>Set <code>email</code> to the destination address for
reports from the daily backup run, or comment out the line
entirely to suppress email reports. If you want reports at
some other frequency than daily, modify
<code>report</code>.</p>
</li>
<li>
<p>Modify <code>prune</code> to control the frequency of
pruning of old backups. It is recommended to leave this as
<code>daily</code>, since deleting a week or more’s worth of
backups takes a very long time.</p>
</li>
<li>
<p>Modify <code>prune_incomplete</code> to control the
frequency of deleting incomplete backups. It is recommended
to keep this at a lower frequency than you take backups, as
otherwise <code>rsync</code> will not be able to use
incomplete backups to optimize new ones.</p>
</li>
<li>
<p>Modify <code>nicely</code> to control the priority of
<code>rsbackup</code>. For example, you might use:</p>
<pre>nicely="nice ionice -3"</pre>
</li>
</ul>
