More importantly, why should I care and what’s in it for me?

I had to temporarily store almost a terabyte on a server and it obviously affected the replica volume. I removed that data and now I am stuck with a monstrous replica volume. The only thing I can see is deleting the protection group and recreating it. There are about 2.5 million images involved here (380 GB) and I dread the thought of deleting and recreating that replica.</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3348824" width="1" height="1">http://blogs.technet.com/b/dpm/archive/2010/02/26/about-dpm2010-scalability-and-new-features.aspx#3342723Thu, 08 Jul 2010 13:04:50 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3342723Ruud Baars [MSFT]<p>This did not change in DPM2010 except that DPM2010 support colocation of Hyper-V, Client and SQL databases.
