we have 2 dpm 2012 R2 UR2 servers backing our 2010 SP3 DAG databases, one backs up the active DBs and the other the passive copies.
I have noticed significant difference in the data throughput where the active copies get backed up in minutes ie. 1-2GB per minute whereas the passive copies get backed up at 100-200mb per minute.
i know the active copies get backed up with the exchange store writer whereas the replication writer backs up the passive copies, is this by design?
we are only taking a nightly sync once of the data
currently the databases in total are <200GB but we are only part way through our migration so this will incrrease 3-4 fold in the next 6 months.
is this the best way to back up the data in two locations without transfer across the WAN links
