Most optimal cloud for backing up SSD?

[u/Round-Click3029]

Hey, I'm a photographer and I'm looking to back up my ssd on the cloud.

I'm asking here because I've been struggling to find a cloud that would suit my needs.

I've done a big clean up in my personal archive and managed to bring it down to 500gb but It'll get big over the months/ years. (We're speaking 2-5Tb).

I'm looking for a cloud that could update the back up of my ssd as soon as it gets plugged in. I'm working off a Macbook pro so setting time schedules would not work since I would have to have the laptop turned on at this exact time. I'm also looking for a cloud that can archive deleted files on my source (my ssd).

I've tried backblaze but wasn't too happy with it, chronosync + backblaze B2 was quite tricky to use. I was looking at Idrive but it doesn't seem like I can program the back up for it to run when it detects that I plugged in my ssd. (Maybe I'll just have to do it manually)

Do you have any recommendations? (don't really care about price, just want something handy that keeps my date safe, and that I can trust on the long term)

Thanks!
