backing up wtmp is like backing up any regular file.
look at the perms and ownership, recreate with the same.
mv wtmp wtmp.backup
chmod 0664 wtmp
chgrp utmp wtmp
if you run fedora (and probably most dists), you can mv the file and
it will automagically be recreated at boot time.
to clean up utmp, truncate it with "> /var/log/utmp"
you will lose your current login records - who,w will show noone
again, most dists do all this for you, so you could simply rm
/var/log/wtmp, reboot, and all is good.
