Availability of Services During Backups
Backing up a Security Management appliance copies the active data set from the ‘source’ Security
Management appliance to a ‘target’ Security Management appliance with minimum disruption on the
originating ‘source’ appliance.

originating ‘source’ appliance.
The phases of the backup process and their effect on the availability of services are as follows:
•
Phase 1—Phase 1 of the backup process starts with the data transfer between the source and target
appliances. During data transfer, services on the source appliance remain running, therefore data
collection can still continue. However, services are shut down on the target appliance. Once the data
transfer is complete from the source to target appliance, Phase 2 begins.

collection can still continue. However, services are shut down on the target appliance. Once the data
transfer is complete from the source to target appliance, Phase 2 begins.
•
Phase 2—When Phase 2 begins, services on the source appliance are shut down. Any differences
that have collected during the data transfer between the source and target appliance since the initial
shutdown are copied to the target appliance and the service is brought back up for both the source
and the target. This allows maintain maximum uptime on the source appliance and no data loss for
either appliance.

If there is an interruption of the backup process and the backup process is not completed, the next time
a backup is attempted, the Security Management appliance can start the backup process up from where
it was stopped.
