Disaster Recovery System Overview
The Disaster Recovery System (DRS), which can be invoked from the main Cisco Emergency Responder web interface, provides full data backup and restore capabilities for all servers in an Emergency Responder server group. The Disaster Recovery System allows you to perform a regularly scheduled automatic or user-invoked data backup. DRS supports multiple backup schedules.
The Cisco Disaster Recovery System performs a server group-level backup, which means that it collects backups for all servers in an Emergency Responder server group to a central location and archives the backup data to physical storage device.
Cisco Emergency Responder provides DRS Email Alerts to System Administrators with status and description of any successes or failures.
DRS restores its own settings (backup device settings and schedule settings) as part of the platform backup/restore. DRS backs up and restores 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 performing a system data restoration, you can choose which servers in the server group that 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 and restore functions
-
Scheduled backups
-
Archive backups to a physical tape drive or remote SFTP server
Note
The tape device must be attached to the Publisher.
The Disaster Recovery System contains two key functions, Master Agent (MA) and Local Agent (LA). The Master Agent coordinates backup and restore activity with all the Local Agents.
The system automatically activates both the Master Agent and the Local Agent on all servers in the server group.
Note |
The Disaster Recovery System does not migrate data from Windows to Linux or from Linux to Linux. A restore must run on the same product version as the backup. For information about data migration from a Windows-based platform to a Linux-based platform, see the Data Migration Assistant User Guide before performing the following the steps. |
