Backing Up Security Management Appliance Data
•
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.

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 services on both the source and the target appliances
are returned to the state they were in when backup was initiated. This allows maintain maximum
uptime on the source appliance and no data loss for either appliance.

During the backup, data availability reports may not work, and when viewing the message tracking
results, the hostname for each message may be labeled as ‘unresolved’.

If you try to schedule a report and forget that a backup is in progress, you can check the system status
by choosing Management Appliance > Centralized Services. From this window you can see the
warning at the top of the page that a system backup is in progress.

Interruption of a Backup Process
Note
If there is an unexpected reboot of the source appliance while a backup is being performed, the target
appliance is unaware of this stoppage. You must cancel the backup on the target 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.

Canceling a backup in progress is not recommended, as the existing data will be incomplete and may not
be usable until a subsequent backup is completed, especially if you receive an error. If you must cancel
a backup in progress, be sure to run a complete backup as soon as possible to ensure that you always
have a usable current backup.
