Configuring CDP Failover

All failover options described below are configured on a per-Job basis. Select the Job for which you want to set failover options from the pull-down menu at the top of the dialog box. If you want all Jobs protected by failover recovery, you must set each individually.

To set up a file CDP failover system

You should configure a second slave Agent at your backup site. It will be kept updated with a read-only copy of the Job's data; if your master Agent is disconnected, you can then use this second Agent as a temporary master so that users can continue to read and write files as usual. When the original Agent comes back online, it will replicate any changes that were made on the temporary master, and you can then redesignate it as master. To automate this process, see Automating CDP failover.

Setting up the second, slave Agent

If you have already deployed an Agent on the computer on which the slave will run, in the system tray, click the Agent icon , click Add this computer to an existing backup Job, then follow the directions. If you have not deployed an Agent on the computer on which the slave will run, download the Agent installer, click Next until you reach the Deploy Backup Agent option, then follow the wizard's instructions.

It is common to use a cohosted topology for this. That is, the second, slave Agent is on the same computer as the backup Server. The slave Agent does not have to be a cohosted with the Server, but if it is not, the Server will have to access the slave Agent remotely in order to automatically become the new master.

If you plan to set up a cohosted slave Agent, when you first connect it to the Job, you must specify the server name using its IP address instead of its computer name. If you specify the Server using the computer name, you will not be able to switch the Agent's mode.
