Sometimes we may need to force backups of the entire server before making important changes to it, and we cannot wait for the scheduled time to do so.
To do so, and assuming that we already have our server backups configured, we must enter SSH, or instead WHM > Server Configuration > Terminal, to open the console, and there type the following command:
/usr/local/cpanel/bin/backup --force
This will show the screen that the backup is starting and creating a log file.
If it does not return that information, it may mean that it is probably already being backed up. We can check if a backup is running by typing:
ps aux | grep backup
If the backup has been running for more than 10 hours, it could be hanging, and the process can be killed from the WHM >System Health > Process Manager, and clicking on the "Kill" option for the process (only one) that has the keyword "backup" in its command line.
