+== BASE-IS-OLD ==
+
+(2018-02) Our nagios check warns us when a backup server has not successfully fetched
+a base backup recently.  The causes often are that either the postgres server or the
+backup host went down or was down during the time of the weekly cronjob.
+
+To re-run a base backup for a specific cluster, log into the backup server
+(either storace or backuphost), cat /usr/local/bin/postgres-make-base-backups
+to see the port for the cluster, and run
+{{{
+  sudo -u debbackup /usr/local/bin/postgres-make-base-backups <host>:<port>
+}}}
+probably best to do that in a screen as it might take a while.
