Backing Up Linux server to a Mac external HD advice?


I’m a web designer that does hosting on the side. My dedicated server uses cPanel/WHM and I have an extra HD at the data center set up for backups but if something goes wrong at the data center, I would not have any backups to back up from. Scary thought.

I thought about individually backing up each customer via WHM and downloading each compressed file, but that is super time consuming to do for every client and I wouldn’t be able to do that very often.

The dedicated server is Linux and I use a Mac. My system admin skills are very limited. Does anyone have any recommendations on how I could best go about this? I was thinking ideally backing up to an external hard drive connected to my Mac. But open to other ideas.

Thank you in advance for any advice.
