Backing Up and Restoring
To run sar on each server
Go to System Management > Tools > SAR.
The system displays results of the command for each server.
Every night, the Polycom DMA system determines whether its configuration
or local user data have changed. If so, it creates a backup of that data, plus the
audit records as of the time of the backup, on each server. It keeps the most
recent ten backups on each server (deleting the oldest backup file when a new
one is created).
The Polycom DMA system’s Backup and Restore screen lets you:
• Manually create a backup at any time.
• Download backup files from the server for safekeeping.
• Upload backup files to the server.
• Restore the system configuration and local user data from a specific
backup file.
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 that you load onto the USB stick.
Note
We strongly suggest that you:
• Download backup files regularly for safekeeping.
• Restore from a backup only when there is no activity on the system. Restoring
drops all calls and reboots the system.
• If possible, make system configuration changes, including restores, only when
both nodes are running and clustered.
• If the system is shut down or in a bad state, use the USB stick to restore.
The following table describes the fields in the Backup and Restore list.
