In our scripts we handle this by copying to a temp directory on the

This is exactly what I always do. I think the way cp is shown in the examples promotes what's really a bad practice for lots of reasons, this particular problem being just one of them.

I've been working on an improved archive_command shell script that I expect to submit for comments and potential inclusion in the documentation as a better base for other people to build on. This is one of the options for how it can operate. It would be painful but not impossible to convert a subset of that script to run under Windows as well, at least enough to cover this particular issue.

A Perl script using the (standard) File::Copy module along with the builtin function rename() should be moderately portable. It would to be nice not to have to maintain two scripts.
