How To Disable Cpanel Full Backup

Whenever clients are generating full back up of their sites all at once and like 10x in one hour, its causing a severe spike in load in the servers

is there a way to disable the full backup in cPanel?

I know mellowhost is able to do this

I also saw this when i was searching google --

Quote:

Additionally, you could just give server administrators the option of disabling
the gzipping of these user generated backups

I believe the gzip process is what usually kills the server when dealing with a
large site. Just tarring up the account would use more disk space, but would
keep processing and load usage down

I don't know how to do that though.

Also I use the Backup function in WHM to generate weekly backups of all my customers sites and FTPing to a remote server. I still want that function. I only want the generation of full backup in control panel be disabled.
