I guess the simplest form is to use "cron". cron is a scheduler that runs things at regular intervals. It takes a file called a crontab file which contains the time and day and month that a program should run and contains the path to the program to run. You edit your crontab file with "crontab -e" and an example would be

# Run daily backup job at 4:40 every day:
40 4 * * * tar cvf /dev/st0 /*

In this example "tar" is used to backup to tape but you would replace this with your chosen method of backing up.

Check out the man page for "cron" and "crontab"

If your utilizing omniback, your cell manager's crontab may initiated the backup...

setup an executable shell script containing the following omniback command:

/opt/omni/bin/omnib -datalist DATAlistname

(review omnib man for more info)

if your utilizing tar, that would be setup on the corresponding linux server...

you would need a backup device:

backup dev filesystem
tar cvf /dev/rmt/0m /home/* > /logdirectory/weekly_home.log 2>&1

another option is dump, which I have not tried....checkup man pages.

hope this helps and happy new-year,
manuel

You do this with the at command or for regular jobs cron

crontab -e

edits the cron file.

Here is an example

30 4 * * * /backupscript 2>&1 | mail -s "backup job" youraddress@yourisp.com

This job runs the backup script at 4:30 a.m. every day and mails the output to your email address

crontab -l shows in non-edit mode the users current cron table(schedule).
