I wrote a script called full_backup.sh to do bakcup. It is supposed to run at a given time everyday. I log in as root, and type "crontab -e" add a entry like following to the crontab file: ******************************* 15 18 * * * /usr/local/bin/full_backup.sh ********************************
The content of the full_backup.sh (I put it under /usr/local/bin) is: ****************************************** #!/bin/sh mt -f /dev/nst0 rewind rm /var/log/tar/snapshot tar -cvpf /dev/nst0 --label="Full Backup Set Created on `date '+%d-%B-%y'`." --listed-incremental=/var/log /tar/snapshot /home/hma/project ******************************************* I can run this script with no problem manually and get my archive file on tape. However, if I use cron, although it IS triggered by cron, the 'tar' command in the script didn't run successfully. That is to say, I know the script was executed by checking the consequence of "rm /var/log/tar/snapshot", but I didn't get the archive file on tape. Strangely, if I changed the backup target directory from the "/home/hma/project" to "home/hma/proposal", then every thing is fine. I get the archive file on tape. "proposal" directory is about 3MB, while "project" directory is about 700MB. But the size should not be a problem, since I can manually run the script to backup "project" correclty. Obiousely, something is wrong with my cron, but I just don't know how to correct it. Currently, I don't have sendmail program installed on my system, so I can't get the email cron is supposed to send to me. Any help is highly appreciated!!
