Assuming zone transfers are allowed:
dig -t axfr zone_name @127.0.0.1 >rescued_zone_file

You can pull your zone data from you secondaries:
dig @secondary-server-name.domain.tld. your-domain.tld. axfr

"rndc dumpdb -zones" might work for you? I have no idea where that file
will end up on your setup though.
Another option: If the zone transfer isn't available as an option, and you
don't have a slave DNS to copy it from either.. I haven't tried this, so I
can't guarantee it will work, but it might work changing the named.conf to
allow zone transfers, then do a "rndc reconfig"? No guarantees that it will
work as expected though :D

If you haven’t restarted the server, you could do an rndc dumpdb and grab the zone content I’d think

I am
running BIND 9.4.3-P1 on slackware 12.2. The server is only for
internal use. I have accidentally removed one of my zone files, and I
have no backup! Is there a way to restore this zone file from the
cache? I looked at rndc and named options, but don't see anything that
will help?
