On friday april 7 one of our backup raid controllers lost two of its four disks. We were unable to repair the damage with the remaining 2 disks in a sufficient way and decided to start over with the backups for the affected hosts. Due to the crash there are no backups available from april 7 and earlier for the following hosts:
The original data on these hosts and the backups on other hosts were not affected by this. New backups for the affected hosts are running since april 8.
