We used to do that, but it was interfering with other programs.  (It's
similar to backup, and we don't want to interfere with e.g. Excel, which
previously was an issue if someone had an open spreadsheet and tried
saving it while we were uploading it.)

I suppose we could switch to using Volume Shadow Copy, I'm not sure why
we didn't try that earlier.
