+### Back Up Pre and Post Actions
+
+When backing up clients hosting services like databases, you may want to run a
+script to snapshot or quiesce the service.  You can do this by specifying pre
+or post wrapper actions.  These will be run on the client immediately before or
+after the rsync operation.
+
+For example, to export the contents of the puppetdb database before running a
+backup of your puppetmaster:
+
+```puppet
+
+class profiles::puppetmaster {
+  rsnapshot::client {
+    cmd_wrapper_preexec  => ['/usr/sbin/puppetdb export -o /root/puppetdb.export --port 8083'],
+    cmd_wrapper_postexec => ['rm -f /root/puppetdb.export'],
