>Here, VSS = "Volume Shadow copy Service". Yes, Microsoft uses the acronym "VSS" for Volume Shadow Copy Service despite having an existing claim on that TLA via Visual Source Safe ie VSS.

That would be 'Volume Snapshot Service', supposedly. The acronym collision probably never occurred to anyone at Microsoft since (it is widely held, at least) nobody at Microsoft actually uses Visual Source Safe.
It's one of those things that was bought, mangled, and re-released to fill a gap in their product line, targetted at those people who must use all-Microsoft, all-the-time even if MS themselves think the tool is worthless.
