Nothing about recovering one from another drive. It has been no end of frustration. I've probably spent far too many hours trying to fix that (but I guess that's another story). Would you believe Calibre runs for about 8 hours to build a new library? And that's only just under 7,000 books. I read somewhere here that someone manages 30,000 books with it and it's not slow for them. For that many books, I'd have to go on vacation and hope it was done when I return. And that's with a new laptop.

Looks to me you are doing something wrong. My Databases are fare much bigger and I do this elementary library movements from A to B on the fly. The only limitation is in my case the hardware for mirroring hard disks or directories. After this is done I only tell calibre where to find the library and this took only some seconds for me.
Why should I rebuild or, what is more doubtful, import a complete library from an intact backup if I only need to copy a library backup from one to another place? I saw this (stupid) advice often in the internet. Not all advices are really helpful. Better to ask at the source for advice from people who know what they are doing.
This way is as old as calibre and had never changed. Backup and restore came much later because more and more calibre users are not able to make one or two directory copies (one for library and one for config directory). They need a button to do it, so Kovid implement this as brainless one click action. (...but, as I often see, it don't help too).
