    Hey everyone,

    I've been trying to code up a backup script that tar's up my server every morning and sends it to an nfs share I have on my windows box. How can I throw it into a cron but keep the date in the log file that it creates?

    Here's what I have, but it comes up with an error in the root mail:

    Code:
    0 3 * * * /bin/backup 2>&1 >> /var/log/backup_`date '+%m%d%y'`
    and the error:

    Code:

    I think that cron cannot interpret `date '+%m%d%y'`. This should better go directly into your backup script, i.e., there should be code in your backup script that creates the log file so that you can remove the >> /var/log/backup_`date '+%m%d%y'` part from cron.
