Automatic Backup

The automatic backup procedure backs up configuration and accounting data in much the same way as the interactive backup procedure. You can run the automatic backup procedure as a cron job if you want to schedule unattended or periodic backups. The automatic backup requires a configuration file, for which a template is located in the sge_root/ util/install_modules/backup_template.conf file.

Comments within the configuration file template indicate what values to use for your environment.

Starting an Automatic Backup

After you set up the configuration file, type the following command to start the automatic backup:

% ./inst_sge -bup -auto full-path-to-configuration-file

To prevent overwriting existing backup files, a date/time combination is added to the end of the backup directory name that is specified in the configuration file.
