TLDR: What’s the best way to backup years of important home video and photos? 2TB and growing.

I have a Mac Studio running Ventura 13.6.1. External HDs are plugged directly into the rear USB-A ports on the back of my mac studio.

I have 2TB (and growing) of photo/video memories on an External WD USB 4TB Hard drive (MainHD). I’m trying to back MainHD up to 2 other locations: another 4TB external hard drive (BackHD) and Crashplan cloud backup.

Right now - when I look at MacHD > Volumes > it’s showing several different “instances” of my BackHD drive - each with a little red do not enter sign - BackHD 1, BackHD 2, BackHD 3 — all the way up to 7. Even when I eject the BackHD drive - these folders are still there.

Also my crashplan cloud backup and lightroom get confused because sometimes it will rename the exHDx drive as well to multiple instances. Any advice? It looks like Crashplan needs another 5 months to finish the last 1TB.

I’m sure there’s a better way.
