My only concern with snapshots, as opposed to backing up regularly, is the accuracy of the snapshot. I think someone used the word "fragile". Is there a reasonable possibility of a chain of snapshots being less than 100% accurate at best or unstable at worst? I use Terabyte Drive Image to back up my HDD's and they are unfailingly accurate. In 15 years of backing up I have had no problems with image fidelity. Can the same be said about snapshots? That is to say, is there a price to pay for the convenience of snapshots, other than performance? And why would performance be an issue with snapshots?
