You can easily mirror the primary using bxcopy or bxtools. We mirror the
primary to a backup - realtime - by simply copying the imail user dirs 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
Then, every 5 hours, 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.
I'll have to say, though, in the 5 years I've been hosting....I have never
had a piece of hardware fail...(knock on electrons)
