If we use SQL Server 2008R2 native backup compression, it doesn’t quite dedupe/compress as well – but the overall file size is still smaller than if we hadn’t done native backup compression.

We were already in a place where we backed up to the network, so timescales were identical.The one thing to bear in mind is that if you are backing up to local or SAN discs, these will be faster than going to the network.
