30 Barracuda Backup Service Administrator’s Guide
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.
