What is SnapshotHelper on Windows Azure

Question

Occasionally (rarely) my Azure website will freeze and eventually return 502 errors (seems like it takes 5 min). I see a whole bunch of items in my trace log related to 'snapshot helper'.

I haven't explicitly used this and google only seems to return results for VMWare. Anyone know what this is? If it is azure taking a backup of my site, is there some way I can schedule it for an slower time than 11:00 am EST?

I don't think you have control over when backups occur, but you can add a second redundant VM so that users will hit this one if the first is unavailable.
