UBUNTU BREEZE 5.10

I have a script -> /usr/bin/backup

--------------------------------------------------------------------------------------------------
rsync -a --delete /var/www /home/max/backup/
mysqldump --all-database --opt > /home/max/backup/mysql_backup.sql
rsync -a --delete /var/mail/virtual /home/max/backup/

umount -f /dev/cdrw
mondoarchive -OVegFw 4 -9 -I /home/max/backup/ -d /dev/cdrw
--------------------------------------------------------------------------------------------------

from my shell with "sudo backup" everythings work fine and I obtain a CD with my backup

This is my root crontab

0 3 * * * /usr/bin/backup

At 3:00 am of every day the script is executed, because I can see the correct day and time of mysql_backup.sql, but the line of mondoarchive is not executed and cd is not burned.

Then I have find on google an howto: (in google search for "mondoarchive cron howto")

but when I type: "grep mondo /var/spool/at/*"

the system tell me: "grep: /var/spool/at/*: No such file or directory"

I hope someone can help me.

Thanks in advance

I don't know what you are looking for in /var/spool/at/. Perhaps you are confusing "at" with "cron" and getting /var/spool/atjobs/, or /var/spool/atspool/ wrong also.
The -g option is for gui mode which won't work in a cron job. If mondarchive outputs on stderr during it's operation you may need to redirect the output to prevent the job from being blocked.
Are you using cd-rw discs? If not the -w option may cause it to fail because it can't erase a cd-r disk. But your device /dev/cdrw indicates this is not the case.

Good Luck!

For -w option-> I'm using CDRW
For -g option-> It's a my mystake

I'm not confused "at with cron", I have only follow the howto instruction.

-------------- This is a crucial part of howto
Use the 'at' command to submit your usual mondoarchive command. My mondoarchive command is:

mondoarchive -D -Ow 10 -S /home/mondo/ -T /home/mondo/ -g \
-E "\"/home/cdaly/GIS/W2K /home/mondo/\"" -9

To submit the mondoarchive command with 'at' do:

at now + 5 min
mondoarchive -D -Ow 10 -S /home/mondo/ -T /home/mondo/ -g \
-E "\"/home/cdaly/GIS/W2K /home/mondo/\"" -9
<CTRL>-d

This generates a script in /var/spool/at/ which sets up your environment and runs your command. Grab this script to become your cron job.

--------------

I would like to know this: when I using the "at" command where are writed the scripts on my ubuntu breeze?
Otherwise: how can I launch mondoarchive with cron?

"at" is used to run scripts at a particular time once. When you use cron instead, that is a different program which runs your script on a regular schedule. There is a /var/spools/cron/lastrun/ directory, but that will probably just tell you when a script was run.

The mondoarchive itself probably produces a log, so you will need to check it's documentation.
You could also have a line like 'echo >/var/log/messages "mondoarchive started $(date)" '
in your script.

Looking in the manpage for the "at" command, there is no /var/spool/at mentioned. Check the manpage on your system.

If the mondoarchive command produces output on the console as it runs, or expects terminal input, that could cause a problem. If that is the case look for a quiet option.

With command "at" UBUNTU BREEZE 5.10 place the script in /var/spool/cron/atjobs/

Now I have followed the howto and everything works right.
