Yes, in fact, given that you've mentioned reinstalling, I'm trying to think
why you would backup more than /home and /etc.

I would be cautious about zipping. This compresses the whole stream,
right? So one bad byte and the rest of the stream is
unrecoverable. Unless you make 2-3 copies. Which would be a great idea
anyway.
Speaking of being paranoid, no one has mentioned comparing the backup to
the original. But I don't know the cpio syntax. I usually pull out the
System Administrator's Guide from the LDP and follow the syntax examples he
provides. But that's tar.
