DR plan |
|
|
I would like some suggestions about the following disaster
recovery plan I'm working in.
Production enviroment:
server1: win2003 DC
Server2 & server3:back-end exchange 2003 cluster with two
Information store each and 2 DDBB in each store.
server3 & server4:front-end exchange servers.
All the servers are conected to a Dell(EMC clariion)
storage (SAN).
The idea is to use as less hardware resurces as posible in
the romote site.
The plan consist in:
1. Install a new server domain member an DC in the remote
site. Different hardware with no external storage, but
with enough internal space.This server will allways have
to be conected to the network for AD sincronitation.
2. Install a single exchange server belonging to the same
exchange organization.
3. Install a backup server so I can restore backup sets
from the primary site.
The exchange database backups should be restored in the
remote exchange server, but I'm not sure if this could be
possible or not.
We have to consider that when restoring exchange DDBB,
production servers (all exchange servers and primary DC)
will be down.
I would aprecciate any possible suggestions or possible
failures on this.
thanks in advance and regards.

All that redundancy except for the most important peice....Active Directory.
You want at least 2 DC's or all the work you are doing will be for nothing
if you AD server decides to have a bad day.
By the way...what does DDBB mean?
Best regards,

As I´ve said in the first point of the plan, there is a DC server member of
the actual domain in the remote site.
By the way DDBB means Data Bases.
Any other suggestion regarding the exchange solution propoused?. Thanks

RE: DR plan |

When doing a DR plan for Exchange you should consider a couple things...
1. how much data loss can you tolerate in event of a disaster?
2. how much time should it take to recover everything?
3. how difficult will all of this be?
you are talking about sending backup images over the network, which isn't
too bad, however in the event of a site disaster you might lose about 24 hrs
worth of email data which is unacceptable in some companies. A better
solution might be to use a form of host-based replication either from EMC
(RepliStor) or a competing product such as XOSoft WANSync HA. Of course
these products will be more costly from a network utilization perspective,
but the price may be worth it. Both products offer mechanisms to support
failover of Exchange databases over the IP link.
When determining any time of DR strategy, I find it's best to get the
business folks involved and propose the problem to them... how much data loss
can they deal with?? Are there certain users who must have a higher level of
availability?
