Check_MK rack1 Mark III - Manual

11. Backup
In order to preserve your monitoring data in case of a hardware failure or similar destruction, a backup
of your data can be configured via your appliance's web user interface.
To be certain the data really is backed up it must be saved to another device, e.g., a file server. For this,
via
mount
management, first configure the network file sharing to be used for the backup. This will be
defined as the target when configuring the data backup. Once this is completed a backup job can be
created that at predefined intervals saves a backup of your system to the shared network.
The full backup includes all of the configurations defined on the system, installed files and likewise your
monitoring instances.
The backup is executed (online) during active operations. This can however first be fully-realised when
all monitoring instances on the appliance use Check_MK 1.2.8p6, 1.4.0i1 or a Daily-Build from or newer
than 22.07.2016. Active instances using older versions will be stopped before, and restarted after the
backup.
11.1 Automatic backup
To set up an automatic data backup, configure one or more backup jobs. A backup data set must be
created on the target system for each backup job. When each new backup is completed, the previ-
ous backup will be deleted – meaning that on the target system double the storage allocation will be
temporarily required.
The backup does not manage multiple generations. If you require more copies over an extended time
frame to be retained, you will need to create these yourself.
11.2 Configuring the backup
With help from
file system management
first configure your network file sharing. In our example a
network file sharing is configured under the file path /mnt/auto/backup.
Next, select the Appliance Backup item in the web interface's main menu, and in the next menu open the
Backup target. Then create a New backup target. The title's ID has a free syntax. Under the target di-
rectory for backup item, configure the mounted file sharing's data path - in this case /mnt/auto/backup.
The Is a Mount-Point option must be active if you are backing up to a network file sharing – this verifies
to the backup that the file sharing really is mounted.
