Check_MK rail2 Mark I - Manual
10.6.1 Disaster recovery
If you need to completely restore an appliance the disaster recovery runs the following steps:
• You have an appliance with the factory default configuration (a new, identical appliance, or an appli-
ance that has been reset to the factory default).
• Ensure that the firmware version matches that of the backup.
• Configure the following minimum settings on the console:
– Network settings
– Access to the web interface
• In the web interface, configure:
– the backup target from which you wish to restore.
– for an encrypted backup, upload the security key.
• Now start the restore as described in the preceeding chapter.

10.7 Monitoring

From Check_MK version 1.4.0i1, for every configured backup job the Service Discovery on the appliance
has a new service: Backup [JOB-ID]. This service informs of potential problems with the backup, and
displays useful values such as size and duration.

10.8 Special features with clusters

The complete configuration of the backups, including the encryption keys will be synchronised between
the cluster nodes. The cluster nodes run the backups separately, and likewise save separate directories
for their backups on the backup target.
The active cluster node backs up the complete appliance, including the data from the data file system
and the monitoring site. The inactive cluster node saves only its local appliance configuration.
Thus, when restoring a backup, only an active cluster node's backup can restore the monitoring in-
stances.
