Should DRF be running on Subscribers?

                   Hi guys,

We currently are currently running 1 Publisher and 2 Subscribers and while checking the alerts in RTM have noticed "Critical Service Down" DRF Local Service, this is just on the Subscribers and not the Publisher. Master and Local DRF Service is running on the Publisher.

Am I correct in believing that the DRF Local process should not be running on the Subscribers?

Thanks,

Shaun

Should DRF be running on Subscribers?

Hi Shaun,

Yes, DRF local should be running on all Subscribers.If it is not running, your backup won't succeed.

Master Agent Duties and Activation

The system automatically activates the Master Agent (MA) on the server.

The system automatically starts the Master  Agent service on each node of the cluster, but the Master Agent is  functional only on the First node. The Master Agents on the subsequent  nodes do not perform any functions.

Duties That the Master Agent Performs

The Master Agent (MA) performs the following duties:

The MA stores system-wide component registration information.

The  MA maintains a complete set of scheduled tasks in an XML file. The MA  updates this file when it receives updates of schedules from the user  interface. The MA sends executable tasks to the applicable Local Agents,  as scheduled. (Local Agents execute immediate-backup tasks without  delay.)

You access the MA through the Disaster  Recovery System user interface to perform activities such as  configuring backup devices, scheduling backups by adding new backup  schedules, viewing or updating an existing schedule, displaying status  of executed schedules, and performing system restoration.

The MA stores backup data on a locally attached tape drive or a remote network location.

Local Agents

The server has a Local Agent to perform backup and restore functions.

Each server in a Cisco  Unified Communications Manager cluster, including the server that  contains the Master Agent, must have its own Local Agent to perform  backup and restore functions for its server.


Note By default, a Local Agent automatically gets activated on each node of the cluster.


Duties That Local Agents Perform

The Local Agent runs backup and restore scripts on the server.

In a cluster, the Local Agent runs backup and restore scripts on each node in the cluster.


Note The Disaster  Recovery Systemuses an SSL-based communication between the Master Agent  and the Local Agent for authentication and encryption of data between  the Cisco  Unified Communications Manager cluster nodes. DRS makes use of the  IPSec certificates for its Public/Private Key encryption. This  certificate exchange gets handled internally. You do not need to make  any configuration changes to accommodate this exchange.
