Not pricey, e2ee clients, open source, servers in Germany, 10gb free tier to try them out. Been using them for a few years now. The clients used to be a bit crap but they're very good now.

I can recommend Hetzner Storage Boxes. The company is located in Germany, but you can choose server locations in Germany and in Finland. You can set it up with Rclone's Crypt feature to encrypt all your files.

Others have suggested: encrypt data on your side and you don't need to worry about where you store it. Cryptomator is a good option.
As for storage, the feedback on Hetzner boxes seems to be good and i'm happy with mega.

Just use client-side encryption, then it doesn't matter where it goes

Then don't go to the cloud! (or use encrypted storage if you really have to)

My view: Unless I can access the hardware 24/7/365 the data isn't mine for 'they' can deny me access to my data anytime while they keep full access. (hence store it decryped)

Borg Base offers EU based server locations. They have been awesome to work with.

if this is for privacy i'd just use the cheapest/fastest option that supports rclone and use its encrypted upload feature.

• shadow.tech (fast, not so expensive)
• Proton Drive
• or look for a managed Nextcloud solution (Murena Workspace, etc.)

Syncthing for synchronization between devices, then rsync to a couple of flash drives for cold backup.

The setup is so easy, you don't even need a server for this, just your ordinary PC.

There is no more paranoid solution than owning your files on the devices you own as well, so you never have to trust the third party.

Additionally, clunky all-in-one self-hosted solutions like Nextcloud bind you to their ecosystem, so it may be hard for you to switch to another one.

Just a plain file backup to your own storage will always be a savior for your lost data, regardless of third party apps or infrastructure.

As the prices widely varry by storage size, you may want to add a size estimate, but i can say that anything above a couple tb is probably more expansive than finding a selhosted solution.

I currently use Infomaniak object storage with restic. I like it since it's Openstack and if they ever go to shit I can easily switch to another Openstack provider. OVH is also one I have used in the past.

pCloud is pretty good, and there is an option for an EU server. It doesn't have a Linux client though, so now I use Jottacloud, which is hosted in Norway and has a (CLI) Linux client that works quite well! I also have a locally hosted Nextcloud instance as another backup. More backups is always good!

I used to use B2 before the whole CEO financial issues came out (not another one accused of something unsavoury) and wasn't sure how it's going to pan out. I switched to a cheaper (per GB) Hetzner storage box and am super happy with it

I use restic, specifically https://github.com/garethgeorge/backrest for making backups and uploading them via rclone.

https://ihostart.com/ one of the cheapest I know.

https://ardrive.io/ for a permanent, encrypted, decentralized, blockchain based solution.

I know you specifically asked for non-US back up solutions, but I honestly don't think you can beat Backblaze's personal tier, as far as pricing. $99 per year for unlimited storage. Solid company, I've been using them for years. If you are encrypting your backups, and following the 3,2,1 back up schema, should Uncle Sam grab your backup, it's pretty much useless and you still have a couple backups in hand. You can encrypt with VeraCrypt or similar, and push that up the pipe to BackBlaze.

The caveats to using BackBlaze are, whatever you are backing up, has to be connected to the PC/Server. So, no NAS although someone here mentioned a work around for that, so if you go the BackBlaze, make sure you ask here what that option is because my frail brain cannot remember what the name of it was, but apparently it works well. Other such options would be rclone, Mountain Duck, ExpanDrive, or odrive. These are unofficial softwares, and can/could lead to termination of your account. Secondly, if you're pushing aver 10 TB to BackBlaze and you need to restore, 10 TB is going to be a bitch to do online. However, you can 'rent' a HDD from BackBlaze. They'll mail it to you, you restore your data, and send the drive back for a full refund, or keep it should you wish.

I receive no compensation from BackBlaze for this recommendation.
