I have asked before and garnered enough info to reliably back up Calibre and all my libraries, but I still have questions.

I run Calibre in Win7 and have no real understanding of what this is about:
Library Maintenance > Library Metadata backup status > Queue all books for backup. What does queuing the books actually do?

I did this once long ago and it took forever. If it had renumbered the books to compress the folders and eliminate gaps left when I delete books, this alone would have tempted my anal retentive desire for order. It did not appear to do anything, however, and since that time I have backed up my books and metadata using FreeFileSync.

Am I failing to properly maintain Calibre if I do not queue the books?

Thanks.
