Gzip and backup_sign Hogging CPU usage

[soarchrist]

I'm worried my dedicated server is being overloaded with CPU usage for no reason.

Anyone have any idea why Gzip and backup_sign are hogging all my CPU usage? I have two backups scheduled daily to be done at 1:00 and 1:30 AM... not right now at 6:38pm. And it's not a time-zone issue. Why would this be running a backup of some kind.... and how do I find out how to turn it off?

Thanks for any advice. Here's my TOP output.

I think I figured it out. Plesk has been trying to do backups of client's files and trying every 30 minutes after failure. I'm not totally sure why it's failing, but the CPU hogging is b/c of it.
