new D2D and is going to recover data directly to the server from the Data Center D2D
appliance over the WAN (which will take a long time).
• The target is co-located onto the remote site and connected via iSCSI (LAN), FC or NAS
New server hardware has been purchased and installed and the admin now wants to
recover data to the server. The admin decides to move the D2D appliance that was in
the Data Center to the remote office (maybe only temporarily) in order to recover the
server data.
In this mode, the mapping is broken to promote the share or library.
IMPORTANT: This configuration is possible in only limited situations because it will
break any other backups or replications to the Data Center appliance. In a simple
Active-Passive scenario, however, this may be a very good model.
IMPORTANT: If you replace the disks in the source D2D appliance and keep the original
appliance, the source to target mapping will still exist on the repaired D2D appliance. You MUST
break this mapping BEFORE carrying out recovery. If you do not, the now blank Source Share or
Library (on the replacement disks) will overwrite the data on the Target Share on Library. You will,
effectively, lose backup data on both Source and Target devices.
