Check Rear backup

Script: check_rearbackup

This check can verify the age of all iso files in the backup target directory.

Requirements

There can be a permission issue to reach the backup target directory. On our servers the backup target is using a user imlbackup. To give access to its resources we added the group “imlrear” for icinga.

$ id icingaclient
uid=1041(icingaclient) gid=1041(icingaclient) groups=1041(icingaclient),1056(imlrear)
                                                                             ^
                                                                             |
