I have only had it dump the old snaps (due to excess load) when they were on the same physical drive. On one server I added another drive just to hold the snaps and have not had a problem since (with Windows 2003 server). What version of Windows server are you running (2003 or 2008?)

I have no end of issues with VSS, even though the store is directed off to a new controller and set of spindles, it seems when IO climbs to any moderate level, VSS tanks and kills all the old snaps, even when it's not performing a snap! Why it needs to tank all the _old_ snaps I have no idea. I hate it... On my file servers with it enabled, it seems that large IO is met with pauses and disconnects regardless if a snap is being performed or not. jlc ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
