I switched over to Proton from Gmail about 8-10 months ago and it’s been great so far. Folders and filters have been like what I was used to. The only thing I haven’t played around with much is calendar and invites.

I ended up going for the whole proton bundle since it included the vpn, storage, and custom domains (up to 10 addresses I think)

This is crazy and scary. I had no idea a system like that existed.

I have some answers that might help but there’s a few pieces that I need to write out on something other than mobile. Will reply back in a day or so.

You could actually use Backblaze for both scenarios: as a normal cloud storage where you can access stuff back n forth or for long term backups and storage.

I use Duplicacy to copy and encrypt my main folders once a week. But you can set schedules for backups as you wish. Depending on how much you’re backing up it may get a bit pricey though. I have a little under a couple terabytes backed up and pay around $6 for Backblaze. They have a client I’ve never used that might be helpful as well.

One thing I wanna look into is using Duplicacy to also back up really important documents to my proton storage.

Seconded. Subscribed to it a month ago in my mission to cut my dependence on Google products. So far I’m loving it. Calendar is a bit basic but it is encrypted.

Between the 500gb provided with the proton suite and using backblaze for backups, I’m pretty covered with data.
