Title: How do you change the backup schedule in flexbackup?
Post by: MJB on December 14, 2006, 07:48:48 PM

I have a simple question with a not-so-obvious answer: How do you change the backup schedule in flexbackup? By default, it runs a full backup every night. I want to change the schedule so it runs the backup only on Friday. Not putting a tape in the drive will take care of Monday through Thursday, but the system will run a full backup on Friday, Saturday, and Sunday.

After a little digging, I found the backup entry in /etc/crontab, and it would be easy to change. However, this file contains the standard warning:

!!DO NOT MODIFY THIS FILE!!
Manual changes will be lost when this file is regenerated.

Where do you make this change so it becomes part of the system config?

First you need to read this portion of the "Development Guide" to understand how the template system works and how to create "custom-templates"

http://mirror.contribs.org/smeserver/contribs//gordonr/devguide/html/devguide.html#TEMPLATES

Then copy the standard template /etc/e-smith/templates/etc/crontab/backup to:
/etc/e-smith/templates-custom/etc/crontab/

Then edit the custom template to suit your needs.

Then you must expand the template so it writes your changes to /etc/crontab like this:

expand-template /etc/crontab

Thank you for the information. That was an easy change to make, once I knew where to do it.

I am also interested in making a backup once a week, so I followed this topic with great interest. However I get lost, when editing the backup template.

Do I need to add $backupDay, and than it should apple to configure in server-manger after a reboot ?

Thanks for input

Let me explain the whole process step-by-step:

1. Login on the server console as root.

2. If the custom template's directory does not exist, create it.

mkdir -p /etc/e-smith/templates-custom/etc/crontab

3. Copy the standard backup template to the custom template directory.

cp /etc/e-smith/templates/etc/crontab/backup /etc/e-smith/templates-custom/etc/crontab

4. Edit the custom backup template. The lines to be changed are located at the bottom of the file. crontab identifies the days of the week as 0 - 6, where 0 is Sunday and 6 is Saturday. In this example, I am changing the reminder and backup days to Friday (5).

vi /etc/e-smith/templates-custom/etc/crontab/backup

Change "$reminderMin $reminderHour * * * root" to "$reminderMin $reminderHour * * 5 root"
Change "$backupMin $backupHour * * * root" to "$backupMin $backupHour * * 5 root"

Save the file.

5. Expand the template to make it apply the changes to the crontab file.

expand-template /etc/crontab

To verify that the changes were made, display the crontab file and look for the backup lines near the bottom.

cat /etc/crontab

These changes take effect immediately. You do not have to reboot the server.

Great - Thanks for the easy-understanding reply. /etc/crontab now is corrected.

There is a lot more I have to learn. I did not know that the stars was for indicating running in minutes, hour, days or months.
