DMA OperationsGuide Backing Up and Restoring
382 Polycom, Inc.
The Polycom DMA system’s Backup and Restore page lets you:
•Manually create a full or configuration-only backup of that cluster.
•Download backup files from the cluster for safekeeping.
•Delete backup files to free up disk space.
•Upload backup files to the cluster.
•Restore from a configuration-only backup file, returning the system state
to what was backed up and leaving transactional data stores (including
logs, CDRs, and audit data) empty.
•Restore from a full backup file, returning both the system state and the
transactional data stores (including logs, CDRs, and audit data) to what
was backed up.
In addition, the Polycom DMA USB Configuration Utility (on the USB stick
used to initially configure the network and system parameters) can restore the
Polycom DMA system from a backup file (full or configuration-only) that you
load onto the USB stick.
The following table describes the fields in the Backup and Restore list.
Note
The system may delete backups to free up disk space if necessary.
Note
We strongly suggest that you:
•Download backup files regularly for safekeeping
•Delete backup files after downloading in order to free up disk space.
•If you need to preserve transactional data and be able to restore it, regularly
perform a full backup and download it from the cluster.
•If you have a superclustered system, download backup files from each cluster
(each cluster’s backup files include only the call, conference, and registration
history for that cluster).
•Restore from a backup only when there is no activity on the system. Restoring
terminates all conferences and reboots the system.
•For a two-server cluster, make system configuration changes, including
restores, only when both servers are running and clustered.
•If the system is shut down or in a bad state, use the USB stick to restore.
