Multi Site DFS Backups

Hey Experts,

I'm wondering if anyone has seen this done before, or has any guidance on the feasibility of this layout:
I'm considering setting up DFS on 3 geographically separate servers (running 2k3) all syncing back to a hub server in our corporate office.  The first reasoning here is high-availability for our network files.  A second benefit I'm hoping to achieve with this is reduction of backups...  would it be possible to forgo the data backups in the remote locations, assuming the data is being synced with DFS?  Will the synced data on the hub server be a full fidelity file that I can do a restore from in the case of data loss in one of the remote locations?

I am open to third party software that would allow me all of the benefits of DFS namespaces along with data mirroring if you can think of one.  It's hard to beat the price of DFS, though!

Thanks a lot, and any suggestions/experiences help tremendously!

You could but you know what they say about, "assume".
How much data is part of the DFS?
What you are saving with a DFS at each remote location is bandwidth and time.
Are you using ntbackup or some other backup solution?
Using backups at each remote location along with Corporate provides you some added flexibility in terms of scheduling backups, but it all depends on what backup options exist at the corporate location.

Oh yeah...  VERY familiar with what happens when you assume.

I'm not entirely sure about the amount of data in DFS.  I think it's safe to say ~200 gigs per location.  Currently we are using Veritas at all locations, on each of the file servers.  I guess what I'm really looking for is a way to consolidate the backups to the corporate office while offering a copy of the files locally at the remote locations.

You could consolidate the backup at the corporate office and have each remote office access the DFS server at their location as the primary.
You would need win2k3 R2 for DFS replication you do not want to use the same mechanism used for sysvol synchronization.
 
An option instead of local backup at the remote location is to use the shadow copy of some of the more important DFS shares that will allow you to maintain a version of prior contents just in case you need to recover/revert something.

Was looking for more of suggestions and guidance than a concrete answer to an issue.  Arnold accomplished that.

Thanks
