Routine Maintenance

Free up space on backup1

backup1 is our primary customer backup system. As usage grows over time, it needs to be regularly purged of old files. The easiest way to do this is by removing deprecated files. These mostly consist of cancelled customers or temporary dump/storage files (created during dump/restores). Our standard policy is to hang onto cancelled customers for 6mos after which we remove their files (as far as customers know their data is purged immediately, but we hang onto it just in case.. and in some cases we cancel a server due to non payment so this makes it easy to restore their system). To find files to remove:

[root@backup1 ~]# cd /data/deprecated/
[root@backup1 /data/deprecated]# ls

virtX_old and jailX_old are permanently archived, so ignore those as well as anything else marked not to delete or otherwise suspicious. Likewise, probably a good idea to try to hang onto oldTEMPLATE.gz as long as we can as well.

So to remove files from 6 mos ago (running this in Oct):

[root@backup1 /data/deprecated]# ls old*201204*
old-1012-cxld-20120411.tgz  old-2068-cxld-20120424.tgz
old-1381-cxld-20120404.tgz  old-col00123-mdfile-noarchive-20120417.gz
[root@backup1 /data/deprecated]# rm old*201204*
