Killing cPanel Backups via Command Line / Shell

From time to time you may find the cPanel backup system taking longer and affecting production hours for websites. The following commands will kill the cPanel backup processes. Running the below commands twice may be necessary:

killall -9 cpbackup
killall -9 backup
killall -9 tar
killall -9 gtar
killall -9 pkgacct
killall -9 gunzip2 
killall -9 pkgacct
service cpanel restart



If it is still slow afterward run:

ps aux


Locate the backup process with the high load and run: 
kill -9 #process
