Barracuda Networks 4 - Loss of Communication to Destination and Queue Size; Temporarily Disabling a Destination

Site-to-Site Replication 29
Temporarily Disabling a Destination
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 attempt to communicate with each other and, if successful,
perform the backups.
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 is queued and errors generated. Data is 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 is actually copied to the destination. Some of it is deduplicated as
the replication proceeds. Only those parts that are not already stored in the remote location are sent
over the Internet.
