I don't think it is a calibre programming problem using the calibre copy to library function. I suspect it uses OS copy functions.
What has so far worked flawlessly for me is using winrar to archive the library and unarchive it in new location.
I get winrar error messages on occasion saying path name is too long and coincidentally these are usually the missing books.
At least it tells me and I can fix the problem immediately.

The "path too long" sounds like the problem here. Windows allows up to 260 characters in a path, not counting file names. I suspect that wherever you're backing up your calibre library has a longer base path than its original location (for example, if your library was in "c:\foo" and you backed it up to "c:\foo\backup", that extra "\backup" string may be just long enough to break some of the longer paths). It sounds like your normal library location is safe, just that you're losing them on backups (not sure about the OP's problem), so try backing them up somewhere else or simply leaving them in .rar format unless/until you need to unpack them back to the original library location.
Edit: This was specifically in reply to speakingtohe and her long path issues with backing up, and does not speak to dmcd's problem at all.
