We had an event last night that we REALLY don't want to go through again - 
we're still trying to figure out why/what happened, but the short form is that 
our AD DNS entries all disappeared.

Luckily we had a Linux box running a slave DNS that we could restore to the 
previous day and convert to a master DNS.

We're still in cleanup mode.

What are people on this list doing to backup and recover DNS? (and I'm NOT 
talking 'recover AD' - the bulk of the authentication/login processing, and 
other such were working just fine; we only lost DNS).

Our total outage was in the order of nine hours, FWIW; without the Linux slave, 
we could still be down.
