Barracuda Networks 4 Specifying Data Replication Destination, Disabling a Destination Temporarily

Page 32

Once a destination has been added, it will appear in the Sending Data To table. If it shows as online, that means that the two systems are able to communicate with each other.

Specifying Data Replication Destination

On the BACKUP > Replication page, there is a global flag to replicate all data to either Barracuda Cloud Storage or to Barracuda Backup Servers. If you want to send data from diverse sources to both of these options, then do not set that flag. Instead, edit each data source on the BACKUP > Sources page and specify where its data is replicated.

Disabling a Destination Temporarily

You can temporarily disable the site-to-site replication feature for one or more destinations. If it is disabled, nothing is sent from the Barracuda Backup Server to the destination until the feature is enabled or until 24 hours have passed. This allows you to move the destination system to a remote location, say, without getting backup errors. If the 24 hours pass without a manual re-enabling of this feature, the Barracuda Backup Servers will attempt to communicate with each other and, if successful, perform the back ups.

To disable site-to-site replication temporarily, go to the BACKUP > Replication page. In the Sending Data To table, click on the Settings link beside the destination Barracuda Backup Server. On the Replication Target Settings page there is a setting to disable data replication for up to 24 hours.

Loss of Communication to Destination and Queue Size

If there is a loss of communication between the Barracuda Backup Server and its back up destination for any reason, the data to be backed up will be queued and errors generated. Data will be queued until the issue is resolved.

The queue size in the table on the BACKUP > Replication page indicates how much data is waiting to be replicated. Not all of this data will actually be copied to the destination. Some of it will be deduplicated as the replication proceeds. Only those parts that are not already stored in the remote location will be sent over the Internet.
