vSphere 4 and DR

What do we need to backup to restore our vSphere 4 infrastruture in the event of a disaster.  I'd guess its something to do with the vCenter server but i can't seem to find any documentation.  
Our VM guest DR is in hand.

for VM DR guest you can choose:
a) VCB from VMware
b) Veeam
c) Vizioncore
d) Platespin or Platespin Forge

for vCenter you can choose to:
a) Use physical machine and DR with imaging system and backup using SQL backup
b) Use a virtual machine and use VM DR method and backup using SQL backup

Hope this can help you,

yes backup the VC database, very important if ur VC server went down
if u consider high availability consider a clustered VC using a clustered SQL DB
Disaster Recovery and Backup are two different things of the same breed.

In vSphere, VMware is also providing a product known as VMware Data Recovery that is an image based, disk based solution.

You seem to suggest your VM recovery is taken care of and everyone else has come up with some good suggestions above so I won't bother.

Virtual Centre is obviously a key component for all the fancy features,  back up the SQL database and keep the install media to hand,  alternatively make the VC server a VM and protect it like the rest of your VM's.

ESX host wise,  well I personally favour the scripted install path.  I use the ESX Deployment Appliance and keep a copy of the scripts.  In the event of a host failure,  scripted install can be used to redeploy the whole thing including configuration in a very short space of time.

Some people have a number of unlicensed ESX hosts at DR sites,  if you have a disaster you've lost all your production ESX hosts anyway.  Recover VC and you can immediately re-licence all these DR hosts for immediate use.
