Are there any plans to add Proton Drive as a backup provider? I see that rclone has made a way to backup and I would love to see this happen so that I can finally de-googlefi.
Few thoughts (my opinion only, I’m not Duplicacy developer and don’t influence roadmap)
- Proton drive does not offer official api. Anything that is built reverse engineering the protocol will be doomed to perpetual instability. I don’t think it’s a good idea to destabilize duplicacy for very dubious benefits in return. If proton releases go bindings with support — then maybe it can be revisited.
- As you said, since rclone already has beta support, you can use rclone serve as transport via pre and post duplicacy scripts.
- Proton Drive is significantly overpriced and quite pointless: duplicacy already provides end to end encryption, and there other much cheaper and faster storage providers. Furthermore, being the drive provider, it will likely to suffer from the same shotcumind other drive services exhibit supporting this abnormal usecase (access to massive number of small files). It wasn’t designed for this, and if any issues arise, users will be on their own.

For those who have a Proton Family membership for Proton mail, VPN and other services, the 3TB that’s included would be perfect to store Duplicacy backups.
I totally get it’s no priority though, it is pretty niche.
I agree, I’m a visionary user and get 6TB but I’m tired of paying for Google Drive. I’m going to switch over for backblaze for my server backups that use duplicacy, just would be nice to push to Proton
There are go bindings now.
Any progress on that?
You can use rclone serve as an adapter.
Thanks for the insight, @saspus.
I’ve switched over from Microsoft to Proton and was wondering about Proton Drive support, but like you implied Proton Drive isn’t a mature product and it is aimed at a different market.
I signed up Proton primarily for the aliasing, the super fast VPN, and having my email account stored in a country with solid privacy laws.
The Proton Storage is a nice to have, but even as of March 2026, Proton has not released a Linux client for their cloud storage.
I see if I can be creative with sending a copy of my local storage (Duplicacy backup target) to Proton Storage using RSync.
It may be convoluted, but its better than not having any options available should my house burn down.
If it’s a real pain, I’ll just spread my backups across free accounts as I’m unemployed and am ITing on the cheap, or I can reach an agreement with a friend to backup to their self-hosted cloud.
I just want my data in more than a single physical location on a provider that does not make me feel dirty.
