Wouldn't just restoring /var/lib/dpkg cause inconsistency problems under
/var/cache/apt ? I would worry about not having the specific package
versions available unless they were in stable. Packages in stable don't
change much, but when they do, it's usually for a very good reason and thus
beneficial to upgrade.
My personal preference is to get the latest package anyway. I thus
wouldn't backup the packages, their files (other than config and custom
files) and also their versions. But I can see having the package version
being backed up as being useful to some users and that's why I'm asking
