Backing up and Restoring Messaging System Data
The messaging system backs up the messaging system data on a daily basis at a preconfigured time. The default time
of the daily back up is 2:00 AM in the local time zone. Manual back ups can be done when you need to back up data
before an upgrade or migration.
