Backing Up and Restoring Every night, each Polycom DMA system cluster determines whether its
configuration or local user data have changed. If so, it creates a
configuration-only backup of the system, which includes:
•Local user account information (including local data for enterprise users,
such as conference room attributes)
•System configuration data
•Supercluster and resource management system integration data (if
applicable)
At any time, you can create either a configuration-only backup or a full
backup, which adds all the transactional data, including logs, CDRs, and audit
(history) data.
The backup file is for the cluster, but on a two-server cluster, a copy of the
backup exists on each server. This ensures that the backup files are available
even if one of the servers isn’t running.
The cluster keeps the most recent ten backups (deleting the oldest backup file
when a new one is created).
