Include the backup commands (data_backupand/or config_mirror) in the table for scheduled commands on MX-ONE Service Node 1, crontab, to activate automatic backup of the MX-ONE system.
crontab uses the editor specified by certain environment variables. Use the command man crontab to find out which environment variables. To check the environment variables, use the command echo $variablename. If the editor is unfamiliar, it is possible to change it.
For more information, such as the format of the crontab command, see the online reference manual pages for crontab. Use the command man 5 crontab.
Use MX-ONE Service Node Administrator user (mxone_admin) when executing the crontab command.
Enter the command crontab -e to open an editor.
Add lines containing when to run scheduled commands. The first 5 fields specify when to run the command and the remaining field what command to run (see examples below). It is recommended to allow at least 30 minutes between the different jobs.
The fields must be separated by at least one space. Use a header line (starting with #) to make the information easier to read.
Save the file and close the editor. Crontab installs the new table for scheduled commands.
