Looking for advice on a VMware disaster plan (speeding recovery)

December 30th one of our servers bit it.  We overnighted a power supply that didn't arrive for 5 days, but that's another story (*cough* fedex *cough*).  We had in effect a fairly good backup and recovery model, the server mostly hosted VMware machines, so all we had to do was copy them off and run them on another server.

This is when I learned that copying 200+ gigs of data takes a really really long time (yes, there are 200+ gigs worth of data, not just bloated vmware files) and we would much rather not be down for hours copying data.

We have more than enough space to mirror the data elsewhere, but do not know of replication software that can work across the network and will back up a running VMware on a fairly consistent basis (no more than 10 minutes old on our mail server).  Would be nice if said product would made 1 backup and then do backups on a transactional level thereafter and did not eat my network alive, although I could dedicate a nic for it I guess.

Basically I'd love advice on some software solution that I could hit server A with a sledgehammer and then bring up one of my VMs on server B without lost data.  I know VMotion is capable of this, however that's a level of cost (last I checked) our company is not ready to eat, and it's a little bit more than we need.  Advice appreciated.
