If the archive is very large it is generally not practical to copy it
with file-oriented programs (rsync -H, tar, etc.) because
reconstructing the hardlinks to the pool is slow and inefficient.
You may just want to start over with fresh backups rather than kill a
few days trying to copy the old ones - and just keep the old disks for
as long as you might need to try to recover something old.

But, there is this approach if you want to try it:

You can also image-copy the partition, but that will only work if
there are no errors reading the old copy.

Backuppc will detect missing/corrupt files and update them on the next
run (at least the next full).
