This is a MUST. Need this feature ASAP!

Far from ideal, but this can be done using 'Rclone'. Setup a docker container for 'Duplicati'. In the duplicati UI - 'add backup destination' use Rclone, which can connect to Proton Drive. I have nightly backups from my NAS to proton drive in with this method.

It is *wild* that this isn't released (much more not even updated by the Proton team) in 2026.

using Ionos for this right now but I'd rather move to Proton. Very surprised it's not available yet

Critical. How about a short message to keep us updated on this?

Essential to convince more people to make the transfer to privacy first.

I am actively looking for a European cloud service as a backup for my Synology NAS. Not having to use US based companies is more important than ever. Although Backblaze has an Amsterdam based data-center, the company still falls under US law.
The lack of this future is no pushing me to spend my money elsewhere and not going all-in on Proton.

This request has been here for years! when are you doing something about it? please!

I cannot believe that Proton is staying silent on this feature request. Wake up guys, this is something we as Proton users have been asking for years now

This is the one feature that is preventing me from going all in with Proton. I am stuck now with Microsoft OneDrive and Google Drive. I want to go Europe. Please make this happen!

For the time being the only more or less convenient way to combine hyper backup with proton drive seems to be cloudslinker (if it works...), which I do not trust. And trust is the most important argument why I decided to buy into proton.

New to Proton Drive, long time Synology admin. My workaround:
1- Setup Proton Drive folders on my Mac.
2- On Synology I created a Proton Drive share and configured it as a Synology Drive Team Folder.
3- On my main Mac I configured the Synology Drive software to do a continuous backup job of the local Proton folder to the Synology share.
4- My Proton Drive now stays synced with my Synology which I backup to C2. I could even do a Cloud Sync to another service if I wanted.

Synology Drive Client Sync Task won't connect to the local Proton Drive folder but the backup tasks do. Not perfect but you can backup to your nas if you want.

Agree an option to have backups from on-prem to cloud or cloud to on-prem

Please, stop developping new tool (who says proton meet ?) and add essential features for existing tool requested since many years

This is a must have. I am considering moving away from Proton because of this issue.

I really miss not being able to backup important files on my Synology to Proton Drive!!!

Please!!!

Make Proton Drive available as a b/u venue for Synology Drive.

The posibility to use protondrive as a of site backup (next to searchablle mails) would be one of the last steps fot me to switch and start paying for proton.

As I am a proton unlimited user, I wanted to make use of some synergies to divert my synology backup into proton drive, which, as per today isn't possible at all. Not sure, whether this to be a problem of Synology, allowing only a limited number of 3rd parties to connect, or Proton itself. My impression is it is with Synology. However, are there any plans to provide connectiivity to synology NAS?
The reasons I am trying to achieve this are obvious: data is going to be more secure in swiss based proton servers on one hand and reduction of storage cost on the other, once I could achieve this. Thanks for consideration.

Yes, please. This is really a missing bit of the puzzle
