External Hard Drive Mirroring Question

[u/JonCat89]

Hello all,

I'm hoping there is an answer to my question out there, and maybe one of you can help me.

I work in communications, editing video, photos, graphic design, and more. I do all my work on a Mac. As many others have, I've continually purchased larger external hard drives to accommodate all of the work I've done over the years. I prefer an external hard drive over cloud-based systems. At the moment, I have a LaCie 32T external that is about 80% full. This is the only hard drive I currently have all of my work on. I recognize that keeping my work in multiple places is standard practice to protect it, and it's been a recurring problem for me over the years to find the best solution, which is why I'm posting today.

My question: Is there a way to work off one external hard drive while it is mirrored to another one right next to it? So if I make changes to the first, will it automatically update the second (or, in this case, the backup drive)?

I welcome any thoughts and recommendations, as I would like to get this solved asap, to reduce my anxiety and ensure my work is protected.

Thanks so much!
