I'm not the greatest Windows clustering guy around, but we have an 
active/active cluster, with 2 "virtual clients" (my boss always yells at 
me, telling me to call them "cluster resources" ;-)).

Anyway, right now my quorum drive is on physical node #2, and I backed up 
both virtual clients last night. I only backup the physical nodes every 
weekend, because there's not a whole lot on there that changes - all the 
data is on cluster resource drives (in my case, SQL databases), which are 
assigned to a group (i.e.,group "SQL2" has the resources of a virtual 
client name, IP address, and drives assigned for it's use); group "SQL4" 
has similar resources assigned to it. SQL2 is mounted on node #1, along 
with the MS DTC group; SQL4 is mounted on node #2, along with the quorum 
group). And last night, I backed up both virtual clients - SQL2 and SQL3, 
along with data from the drives assigned to each of those groups.

Hope that helps.

No. I have a few of those, too.
