dfs-r

I have 4 servers, one at each office location, each sharing read/write copies of 1.5TB of data. Changes are replicated 24/7 between all 4 servers via DFS-R. All servers run Windows 2008 R2.

I'm interested in implementing VSS (Volume Shadow Services) on this data. I've read that DFS-R and VSS play nicely together, but I'm left with one unanswered question: turn on VSS at all locations or just one (the headquarters). Can I run VSS at all 4 locations safely, or is it wiser to run it at just 1 location?

Thanks!
