I think I already said something on this thread, but, I don't remember. I use DFS with four servers, have used it with two and three also. It works like a charm for me. I haven't tried it on a WAN, and I think that's where FRS trouble gets a little bit heavier. On a well connected LAN, I know it works fine. --Brian

Subject: RE: [ActiveDir] DFS
The primary goal is to have 2+ servers and have the customer only see
one. Replication is only an added benefit if it works ok. I do have
another question - how many on the list use dfs? In a situation with 2+
servers, is this something you would recommend? Unfortunately, the day
I treaded happened. Our file server died and the last good backup
occurred on weds. So now, the motivation to make smaller servers has
increased.

There are two distinct issues here - having multiple instances of the
same data for redundancy/fault tolerance, and splitting the data among 4
servers for a type of load balancing. I think the latter was the
primary goal, is that right Jennifer? You just don't want 1 tb on a
single server? Yes with DFS you can just split it up and have your 250
GB on each. That keeps you from having all 1000 GB of your files go away
if one server dies, and you'll probably get better response times for
your file access. You can set certain folders to replicate but not
replicate the whole thing of course, and those folders you designate as
having multiple sources and you'll achieve true load balancing and
redundancy for that 20 Mb or so. The main concern, as I understand it,
with the replicated folders is if people are liable to modify the same
files on different servers at the same time or before replication occurs
if it's not immediate. Some data lends itself well to redundancy
(frequently used CD images etc) and some things don't do as well - home
directories for sure, and departmental directories depending on how
they're used. At least that's my opinion from how I've understood it.

I was only thinking about replication between two servers and the data
would be small. Maybe 20 mb here and there - as files are updated.
