So having evangelised file-level copies a few times in this thread, I found
myself wondering if I would have been better off with imaging this very
weekend. Copying a 2.1T filesystem from an internal SATA2 disk to an external
one (my regular backup drive to my once-a-month, lives off-site one) via USB3
took nearly 48 hours via "rsync -a", and the destination ended up bigger,
possibly because one or more of the backups on the source had been using some
kind of hardlink de-dupe (I've ranted about hardlink trees being a problem in
various backup topics on -user, too...) and I didn't think to supply -S to
rsync.

The real test will be how long an incremental catch-up will take in the future.
