This doesn't make a difference for us.  They're asking $50 per machine
per month, thus by having so many different VM's, the total backup
space isn't the primary concern.

For doing serious backup I'd consider pulling a full dump on a regular
schedule a requirement because just chaining several weeks or months of
incrementals together on top of a terribly old full dump is pretty
risky.
