     $rsync $rsync_opts $password Uhuru::rsync \
      /root/uhuru_backup/uhuru/home/ > /var/rsync/uhuru.$NOW.log

The daily backup script works fine when run manually as sudo but doesn't 
complete when run as a root cronjob. I know the script starts because it 
creates a log. When successful it gives a list of files copied but when 
run as a cronjob it's blank (0 bytes)

$ sudo crontab -l
20 21 1 * * /root/uhuru_backup/uhuru.monthly.sh > /dev/null
25 21 * * 7 /root/uhuru_backup/uhuru.weekly.sh > /dev/null
30 21 * * * /root/uhuru_backup/uhuru.daily.sh > /dev/null

This should be impossible but I've got the same issue on two backup servers.

Clive
