OT : Disaster recovery?

[Kevin Miller]

One thing we're going to be looking at RSN* is virtualization.  Be nifty
to set up MailScanner, etc. as a virtual machine.  Then if you box goes
down, you just start up another load the virtual snapshot and away you
go.  The 'snapshot' could live on a completely different server and be
backed up just like a regular file then retrieved instantly as needed.
 
Of course, you'd have to save it afresh every now and then when you
updated MS, clamav, sendmail, etc.  But that's gotta be a lot easier
than building a new box from scratch!

Bear in mind that I haven't yet done this yet, so maybe someone that has
can chime in if there's some significant gotchas...

Of course you are right! I do have a secondary MX setup to catch all the
mail if the primary goes down. That still leaves me having to reinstall
the primary as soon as possible!

I've just done a full backup of my mail server using mondo - now to do
some testing of the restore process!

	Are you sure you cant afford redundancy? Sounds like that's what
you
	need when you say you want to get your mail server back online
quickly.
	
	Consider a redundant machine even its an old server or a PC
(depending 
	on your demands) and then at least you can receive mail while
you repair
	your main machine if required. Even if the second one is only a
backup MX...
