What is VSS Quiescing?

I finally got around to installing one of my versions of Ghost 15 on my main system.

 

But when I create an image in windows and then go to restore it from the recovery disk I get this warning:

 

"This backup was captured when your machine was under high load.  It should recover normally but you may wish to optimize your backup schedule to facilitate VSS Quiescing"

 

I never seen that error before, and it's a little unnerving.  The image did restore correctly but I can't figure out why it's happening.

 

I tried throttling back the performance slider and the image took more than twice as long, but that didn't help.

I then tried the option "Perform Full VSS Backup", and that didn't help.

I then did both, VSS backup and throttled it back and that also didn't help.

I then did all the above after ending every process I could think of and left my system unused and that didn't help.

 

Although this is an old system, the specs are higher than my netbook that run one of my other versions of Ghost 15 and never had a problem.

This has a P4 3.2Ghz with 2GB RAM running windows XP SP3.

When the image is being made the CPU runs between 20-30% usage and I still have over a GB of free RAM availible.

 

Thanks,
