For an item to go unsupported, it usually means something is wrong with the agent, so I add this script to /etc/cron.hourly.

The SQL query to get the list of unsupported items is,

SELECT
hosts.host AS hostname,
items.description AS item,
items.key_ AS "key"
FROM
items
RIGHT JOIN
hosts ON items.hostid=hosts.hostid
WHERE
items.status = 3;

To delete this entry:

Stop backuppc [ /etc/init.d/backuppc stop ]
Search /var/lib/backuppc/log/status.pl for the failed host and delete the entry.
Restart backuppc [ /etc/init.d/backuppc start ]

Debian/wheezy currently has these warnings on startup and in backuppc logs.

Debian bug #650522 suggests surrounding each use of qw(…) with rounded parenthesis: (qw(…)). There are a lot these used throughout backuppc, so I took a slightly less ingenious but just as effective route.

By adding: “no warnings 'deprecated';” to the beginning of each file that uses qw(…), the warnings are suppressed. This change can be scripted by using the following one-liner:

grep -ril 'qw(' /usr/share/backuppc/lib/BackupPC/|while read file; do sed -i "1i no warnings 'deprecated';" $file; done

The location /usr/share/backuppc/lib/BackupPC/ is used on Debian/wheezy and may need adjusting for other distros.

Following a few posts on the Zabbix forums I made a quick and dirty bash script.

If you are sure you want to keep the service pack (most people are) you can save 2-3GB of space by removing these backup files.

In an elevated command prompt, run the following command:

DISM /online /cleanup-Image /spsuperseded

  1. Navigate to the Data folder, ie. C:\Program Files\Electronic Arts\Red Alert 3\Data
  2. Rename the Movies folder to “Movies.renamed”
  3. Start up the game
  4. Set your resolution to the same as your desktop
  5. Apply the settings and quit the game
  6. Rename the Movies directory back to “Movies”
  7. Start up the game and it should work

YMMV.
