Trying to dig through the mountains of different options and suggestions hasn't provided a straightforward answer.
I do hobby photography and am looking for recommendations for photo backup.
I have a MacBook Air running Lightroom, and I import all my photos to an external drive that I work off of. I have a separate NVMe M.2 external drive that I wanted to use purely as a backup device for my photos. Ideally, I'd like it to automatically back up my external drive containing my photos and Lightroom catalog once a month. From doing some reading, people have recommended ChronoSync and Carbon Copy Cloner for this use case. I've read and gotten into the weeds regarding NAS setups and the 3-2-1 strategy, but for now I just wanna get a simple hard copy reliable backup going so I can feel comfortable deleting the photos off my camera memory card (which is my current second copy of most photos).
Should I buy CCC or ChronoSync, or is there a free alternative? Or does anyone have any other recommendations?
