How Does the Site-to-Site Service Work?
The CDP Site-to-Site feature requires a minimum of two CDP appliances to be deployed in a
one-to-one scenario, in which a single upstream CDP appliance is the backup method for a
downstream CDP appliance. The upstream CDP appliance can be deployed locally or offsite
using a VPN or WAN connection, as illustrated in
Figure 1
and
Figure 2
. The downstream CDP
appliance must be configured to backup to the IP address of the upstream CDP appliance, and
the upstream CDP appliance must be licensed for Offsite and have at least one node available.
Multiple downstream CDP appliances can be configured to backup to a single local or offsite
upstream CDP appliance in a many-to-one configuration. Upstream CDP appliances can also
be used as a backup method for local agents, and can back up the local agent data to the
SonicWALL offsite portal or to another CDP. Data, settings and configuration backed up from
the downstream CDP appliance to the upstream CDP appliance are 256-bit encrypted and
compressed, and sent using port 2022. All other features, including alerts, policies, and reports,
can be configured on the upstream and downstream CDP appliances.
In the event of a disaster, data, settings, and configurations (or just settings and configurations)
can be recovered from the upstream CDP appliance to the downstream CDP appliance. If the
data on the upstream appliance is outdated, the option to recover only settings and
configurations provides the ability to rapidly set up the replacement CDP. The replacement will
then recover the latest data directly from its local agents, and then pass this data on to the
upstream CDP appliance, thereby reinstating full backup protection.
If the downstream CDP appliance is rendered unusable, it is necessary to obtain a new
downstream CDP appliance to replace it. The upstream CDP appliance must be notified of the
change and the new box must be configured to backup to it prior to recovering data from the
upstream CDP appliance.
Sample Setup Cases
The diagram in
Figure 1
provides an example of a one-to-one CDP Site-to-Site deployment.
Multiple agents are configured to backup to the downstream CDP appliance (IP address
10.0.0.1). The downstream CDP appliance is configured to backup to the local upstream CDP
appliance (IP address 10.0.0.2).

deployment. Multiple agents are configured to backup to the downstream CDP appliance (IP
