You can schedule custom commands to run on Windows and Linux computers. Custom commands are scripts that are saved on a computer where an Agent is installed, and are scheduled to run through Portal. For example, you could schedule a custom command that shuts down services on the Agent computer, runs a backup, and then restarts the services.
Scripts can be in .bat, .exe, .cmd and .sh format, and must be saved in the following directory on the protected computer: <AgentInstallationDirectory>\ScheduleScripts
To schedule a custom command:
1. On the navigation bar, click Computers.
The Computers page shows registered computers.
2. Find the computer with the custom command, or script, that you want to schedule. Expand its view by clicking its row.
3. Click the Jobs tab.
4. In the Select Job Task menu, click Create New Custom Command.
The Create / Edit Custom Commands dialog box appears. The Custom Command File list shows scripts in the <AgentInstallationDirectory>\ScheduleScripts directory that have not been scheduled.
5. In the Custom Command File list, click the script that you want to schedule.
Command files in the list include .bat, .exe, .cmd and .sh files that have not been scheduled and are saved on the protected computer in the following directory: <AgentInstallationDirectory>\ScheduleScripts
A default schedule for the command appears in the Schedule area.
