The biggest differenct between "quiescent/snapshot" and "just snappshot" is that most databases have to do a recover-step. But that shouldn't be a real problem for any ACID-compliant Database (Which should be just about any, excluding MySQL with MyISAM-Backend). The important thing is that all the data is from the same point in time. It's a simulation of: "Ups, my power just failed". And ACID-complient databases are supposed to recover from that. :-) Bis denn -- Real Programmers consider "what you see is what you get" to be just as bad a concept in Text Editors as it is in women.
