>If there's a hole in my argument I need to know.
Well, it seems clear to me that a version control system is written specifically for that purpose, and a backup system for that specific purpose (unless the designers and authors of the system have made some political statement about overlapping intentions). I’m sure the version software authors try to make the version system as robust as possible, but I did experience a serious corruption of Source Safe a few years ago and we never managed to get some archived old software versions out of it. For that reason I don’t consider a version system any kind of backup at all. At that previous job they were backing up the version backing files to tape, but it was clear that they had been backing up corrupt version files for a year or so. There’s the hole. Greg
