It appears every few times I open the app and the usual android back button doesn’t make it go away, and there is no cancel button. What you have to do is toggle the toggle, then the button will change to “do not back up” and then you can press it. It annoys me how easy this makes it to accidentally turn on backup.
I’ve got both going for dual cloud backup. Immich is hosted local so I’ve got a backup at home, and I pay $5/month for 500GB storage with Google
For me the main issue with that is giving Google money. I’m already paying with tons of my data, that’s enough to me
I prefer paying someone else
Also: in this way when you delete something from a backup it doesn’t get deleted on the other
