For me, its NextCloud or bust, I personally suggest AllSync as a hosted. $10/yr for 50gb with all apps available

I have been playing around with it. Ended up buying more recently of the lifetime stuff. Tried their android app and windows/web interface. Web interface has been 100% rock solid. Android app not so much:

• Camera sync sometimes doesn’t sync all the pictures. Sometimes it doesn’t show synced pictures either, I have to manually navigate to the folder. Not sure whats up.
• Android app has a long delay on starting up sometimes.
• Poor battery optimization comparatively speaking to alternatives (nextcloud & gphotos)
• App occasionally crashes, but that’s stopped recently.

Also, just full disclosure I am on Graphene, so sometimes things are a bit different. Recently, I have started to setup their rclone connection to use it as an offsite encrypted backup of ~ half a terabyte of important shit. Its my 2nd offsite backup and I am planning to regularly test that repository (using Kopia). While I am happy with it so far (outside the android app), I am still a bit wary on how reliable they are. They have been around for a few years now, so I feel more confident, just overall being cautious until I see a public audit of their backend. The client code is all OS (supposedly, I haven’t confirmed beyond the rclone code), so you can check that if you like (which should at least confirm local encryption before transit).

Filen is good and has a very nice interface. It’s fine, but you can also try Proton Drive, Ente, etc.

Pay for stuff if you want something reliable and supporting your privacy. Sure test the free tier to make sure it fits your requirements but please do consider not sticking to it.

Might be Filen (don’t know of it) or Hetzner Storage Box (~10e/month for 5TB iirc) or Proton Drive (Visionary customers have a large quantity, e.g. >6TB) or whatever else you prefer but if you do not actually help people providing services by funding their work they you are supporting BigTech and their “free plans” that comes precisely at the cost of our collective privacy.

I use it and their free plan works fine but I’ve quickly upgraded to a paid tier. They claim zero knowledge E2EE, that’s all I know. Free and paid plans offer the same level of privacy, as far as I know. But, if you plan on sharing files (I don’t) make sure the free plan still offer that feature as I think I remember it was removed awhile ago (but I may be wrong).

I also think most our governments will sooner than later decide those kind of fully privacy-respecting cloud storage should not be accessed by mere users like ourselves (because ‘think of the children’ and the usual bullshit). So, I don’t rely on it as my sole backup, I have another online backup solution (not cloud) and also keep a copy of all my files on a fully encrypted disk drive (two of them, as a matter of fact).

Edit: typos.

I’ve been using their service for a long time now and have been happy. Their GUI client is ok, but they also have a CLI client which I appreciate for automating stuff. I’m however paranoid and don’t upload files as is. Everything is backed up to an encrypted virtual drive which I upload as one giant file.

I’m using their starter lifetime plan, and everything works flawlessly. That’s a plan where you pay only once and keep it forever.
