Anyone use Riverbed, or Cisco WAAS at there work?

yeah stick to DFS-R for user shares. sharepoint can handle locking/revisioning at a higher level.

double-take is a not so free app that is popular, probably runs on win2k and does file wan replication.

DFS-R replicates immediately (well within milliseconds in my tests.) Assuming it is not overloaded and it does not have a back log. Biggest "issue" is locks are not replicated which means if 2 people have the same file open on 2 different replicas and save the "last person in" wins. This is normal and happens even with locks. DFS-R actually detects that the file changes on both sides and will save both.

Also should this manage to happen, newest date wins which yes mimics what your commenting about. The conflict file is still saved however and can be recovered.

This is all a moot issue if you move to a centralized file server model and you do not have the issue with file locks. As the first person to open a file will have the lock on the file. Also, this is why I caveated my response as I was not sure where DFS had made enhancements.

Point taken but I was trying to figure out what prompted it. Centralized may work for some companies. However it will not work for companies doing say, CAD or an engineer working with a 350meg Revit model. That is why I commented to "check your usage." Remote users opening and working with Word / Excel files should be right at home even on a wan link with a compressor.

We tend to be stuck with both here. So we use the compressors on sites that are small and mostly "office users." CAD and Engineering teams are normally attached via a DFS-R replicated share due to the load they can put on the systems. This mix has worked very well for us.

Vivi has not posted a usage model or network diagram (and I wouldn't expect one) but I like to list options and assume he would know his model and make the decisions or ask questions from that.

Now when we can all get 10gig connections to every where for $24.99 / month... This will all be moot!
