A
simple yet effective way to do it:
You can easily mirror the primary
using bxcopy or bxtools from mensk.com.
We mirror the
primary to a backup - realtime - by simply copying the imail
user dir to
the backup. It's not much overhead. In our case anyway, it's
only about 100
mb. Bxcopy is set to copy any files on the primary that
change. You can
install an additional NIC in the machine to handle the
mirroring process if
you want. Bxcopy will copy to a \\ip#\sharedir
Or
you can use Peersync software to mirror, it's got more features I
think.
Then, every few hours, or every 10 minutes, (it's up to your situation),
we run a routine to export
the
[HKEY_LOCAL_MACHINE\Software\Ipswitch\IMail\Domains] key.
This
export is also mirrored to the backup machine. In the event of a
failure,
we just delete the
[HKEY_LOCAL_MACHINE\Software\Ipswitch\IMail\Domains] in
the backup and
import the new one in.

Subject: [IMail Forum] Backup
Server
Quick question:
I was wondering what would
be the best way to be prepared for disaster recovery. For instance
right now we have one Imail server and a backup spooler server. The Imail
server is the 10 mx record and the spooler is the 20 mx record. Now if
the main Imail server crashes then our users will not be able to
authenticate, only their incoming mail will be spooled on the other server
until we can get a the crashed server up again. Can I have two Imail
servers where if one completely went down the other would take over
authenticating and operating as if nothing happened? If so what would
be the most efficient way to set this up? Would I just setup two
servers the exact same way (one with the primary mx ip and the other with
the secondary mx ip) and everytime I get a new user just add it two
both servers?
Any help would be appreciated.
Thanks,
Kris
