Hi
We have, say, 3 servers - A,B and C. B and C replicate their data to
server A via DFS, so all data is on server A - and as such, server A
is the only server that needs to have data backed up.
(B and C back up C: and system state only)
So - assume server B dies and needs a rebuild.....
I KNOW we can build new server, DR server B C: and system state, and
create file tree for DFS on data volume, wait for X hours, and all
data is replicated by DFS and everything is perfect! Woopee!
However, now assume server B is over a 2Mb link and has 30Gb of data,
and clearly we don't want to replicate this over the WAN via DFS.
I understand we can restore the data area of server A (that was
replicated) to server B to server B (using Windows 2003 compatible
backup program) - and then move folders to appropriate loction and
start DFS - and again - DFS sorts it out. (e.g. drive tape to remote
site and restore locally).
What we can't prove in the test is whether data is replicated or
moved/copied from the "preexisting" folder in each DFS share! In the
test lab with full DR replicas of the environment, server A has to be
brought up as "authoritave for all replicated data" (e.g. AD) in order
for AD to work - as there are no other "real" DCs in the test lab -so
we believe this makes it teh master for DFS too - and hence test is
not real.
Can't find any white papers or help on this topic - except "let it
sort itself out" - which is fine - but time consuming with lots of
data over WAN.
Ideas/thoughts most welcome! Any questions, reply here and I'll get
back to you.
THANKS!
