I back up /opt/local/etc for config files; otherwise, software/ is good to
keep archives.
The registry's a bit of a risk, since it will be logically inconsistent if
you aren't backing up the whole install. If I needed to worry about this,
I'd look to dump out just the registry parts relating to archives and write
that to somewhere that is backed up. This could be tricky, as you might
well need to munge entries relating to activated packages so they look like
inactive ones. You'd also want a simple record of what packages were
activated at the time, so the system could be reconstituted from the
inactive dump and then running port activate over the active list. (Come to
think of it. this means backing up /opt/local/etc separately so config
files don't possibly get overwritten. Yes, that would indicate Portfile
bugs, but an emergency restore is the wrong time to discover and try to
deal with those bugs.)
