Backing up DPM using a secondary DPM server
Backing up DPM using a secondary DPM
server
Another option for protecting your DPM server is to back it up with another DPM
server. Your main server is known as the primary DPM server and the other DPM
server is known as the secondary DPM server. The primary DPM server backs up the
protected servers directly. The secondary DPM server protects the databases and the
replicas on the primary DPM server. This provides disaster recovery for your DPM
solution in the event the primary DPM server fails.
Using this solution will allow you to continue backing up the protected servers that
are on the primary DPM server in the event of the primary DPM server failing. You
will have the primary server's database and replicas on the secondary server. You
can use these to rebuild the primary DPM server moving the backup of the protected
servers back to the primary DPM server. It is also possible to switch primary
protection to the secondary DPM server and it is possible to restore to the protected
computer directly from the secondary DPM server.
NOTE : Something that you should be aware of is two new features in
DPM 2010 called Cyclic protection and DPM Chaining :
Cyclic protection : is good for companies with branch
offices. With this type of protection two DPM servers are
able to protect each other. For example, let's say you have
DPM server A and DPM server B; DPM server A protects
everything on DPM server B and DPM server B protects
everything on DPM server A. The data from both servers
(office locations) will therefore exist due to each other.
DPM Chaining : is literally creating a chain of DPM servers.
Each DPM server in the chain protects the next server in the
chain. For example, let's say you have DPM1, DPM2, and
DPM3 in the chain. DPM1 is a primary DPM server, DPM2
is a secondary DPM server to DPM1 and/or primary DPM
server as well, and then DPM3 is a secondary DPM server
to DPM2. A secondary DPM server can protect the DPM
database of the primary DPM server along with replicas that
the primary DPM server protects. Also take note that if a
DPM server that protects its own local data such as: DPMDB,
C:, System State, and so on that this will break the chain.
