Mounting ro should be fine - if you also mount with "norecovery" then truly no
IO should happen. If you're really paranoid, find a utility to mark the block
device itself as read-only, then you've taken it out of the filesystem's hands
completely.
You could also try xfs_copy, it makes a copy of the filesystem and works on the
underlying device, with the filesystem unmounted. There's a man page for it.
