We are
using Double Take for Exchange 5.5 failover and have successfully tested
fail-over on a test server, as well as on a production Exchange
box. Its a bit of a pain to set up, and requires some downtime on your
Exchange server, but it does work. Just make sure you follow NSI's
specific Exchange Server implementation instructions.
Obvious Disclaimer: Play with this in a lab setting before
throwing it on a production server! Practice failing over and back
again. I did about 10 successful failover/recoveries (and countless
unsuccessful ones) to make sure I knew its behavior before going live with
it.

Subject: RE: Geo-Cluster and Double
Take
Hi
Ken,
We
are using DoubleTake with SQL7 and seems to work OK (Since Jan 2000)
Have not had any disasters as yet but do a regular simulation to see if all
is still well (despite strict version control). Best way to casually
check is to look at the replicated Sql files's dates and times and they are
always spot on to the system clock meaning that they are updating the
replica even before the the source writes to disk.(Those files stay at their
old dates of course)
GeoCluster is an attempt to make MSCS less of a farce but I might be
wrong, but I think Sunbelt stopped supporting it due too much problems at
one time.
Don't think anything can help Exchange and FTP should be no
issue.
;-)
Erich
Anyone using or have comments about Geo-cluster
and double take. For use with, sql, exchange and ftp?
TIA
