Err, no.

The root zone changes twice a day and its contents change quite frequently as TLD managers update their name servers, do key rollovers, etc.

If you're going to copy the root zone, I'd recommend using a zone transfer from the name servers described in http://dns.icann.org/services/axfr/ or, at the very least, set up a cron job to pull the root zone twice a day.

WRT the root _hints_ change, setting up a cron job to pull, verify, and install the root hints file periodically (once a month should probably be sufficient) would probably be a good idea.
