Backup Overview
Cisco recommends performing regular backups. You can use the Disaster Recovery System (DRS) to do a full data backup for all servers in a cluster. You can set up automatic backups or invoke a backup at any time.
The Disaster Recovery System performs a cluster-level backup, which means that it collects backups for all servers in a Cisco Unified Communications Manager cluster to a central location and archives the backup data to physical storage device. Backup files are encrypted and can be opened only by the system software.
DRS restores its own settings (backup device settings and schedule settings) as part of the platform backup/restore. DRS backs up and restores the drfDevice.xml and drfSchedule.xml files. When the server is restored with these files, you do not need to reconfigure DRS backup device and schedule.
When you perform a system data restoration, you can choose which nodes in the cluster you want to restore.
The Disaster Recovery System includes the following capabilities:
-
A user interface for performing backup and restore tasks.
-
A distributed system architecture for performing backup functions.
-
Scheduled backups or manual (user-invoked) backups.
-
It archives backups to a remote sftp server.
