Yes I've been reading / thinking more about this, and I've decided
against it. There's no real guarantee that MySQL will have written
everything to the ibdata files at the point when I make a snapshot of
them ( at least as far as I know ). Since the nightly backups are still
working perfectly, I'll just shut down MySQL when the backup completes,
delete /var/lib/mysql, and import the backup. That sounds a lot safer
than anything else at the moment.
Thanks again for your response. At least I learned about lsof and
recovering deleted files :)
