Mount Proton Drive on Linux: rclone systemd Setup Guide
For Linux power users and DevOps professionals, the lack of an official Proton Drive client is a significant friction point. While the web interface handles basic uploads, integrating encrypted cloud storage into your file system for seamless I/O requires a more robust solution. The definitive way to mount Proton Drive on Linux is by leveraging the power of rclone combined with systemd for persistence.
This guide skips the basics. We assume you are comfortable with the CLI and focus on the architectural requirements, performance tuning via VFS caching, and creating a production-grade systemd service to manage your mount.
Prerequisites and Architecture
Before attempting to mount Proton Drive, ensure your environment meets the strict version requirements. Proton Drive support was added to rclone relatively recently.
- Rclone v1.63 or higher: Most package managers (apt, dnf) ship outdated versions. You must install from the official script or binary.
- FUSE (Filesystem in Userspace): Required to mount the remote as a local filesystem.
- Proton Account: A paid or free Proton account (Plus/Unlimited recommended for storage space).
Pro-Tip: Do not rely onsudo apt install rclone. Verify your version withrclone --version. If it is below 1.63, update immediately.
# Install the latest stable release of rclone sudo -v ; curl https://rclone.org/install.sh | sudo bash
Step 1: Configuring Rclone for Proton Drive
Rclone interacts with Proton Drive's API using a custom implementation. The configuration requires an interactive login session to generate the necessary OAuth tokens and encryption keys.
The Configuration Workflow
Run the interactive configuration wizard:
rclone config
Follow these steps carefully:
- Type n for "New remote".
- Name the remote
proton(or your preferred identifier). - In the storage list, look for "Proton Drive". It is usually listed around number 46 (varies by version). Type
protondriveor the corresponding number. - Username: Enter your Proton login email.
- Password: You will be prompted to enter your password. Note: If you use 2FA, the flow handles it gracefully.
- Mailbox Password: If you have a separate mailbox password (rare for newer accounts), enter it. Otherwise, press Enter.
At this stage, rclone will attempt to open a browser window to authenticate and authorize the application. If you are on a headless server, you will need to perform the authorization on a machine with a browser and paste the resulting token back into your terminal.
Verification
Once configured, verify the connectivity by listing the root directory:
rclone lsd proton:
If you see your top-level folders, the API connection is successful.
Step 2: Manual Mount and VFS Caching
To mount Proton Drive effectively, we cannot treat it like a block device. We are interacting with an API over HTTP. To make this usable for standard POSIX operations (opening files, writing logs, appending data), we must use Rclone's Virtual File System (VFS).
The Mount Command
Create a mount point:
mkdir -p ~/mnt/proton
Run a manual test mount. We use --vfs-cache-mode full to ensure file writes are buffered locally before being uploaded. Without this, some applications will fail when trying to write to the mount.
rclone mount proton: ~/mnt/proton \ --vfs-cache-mode full \ --vfs-cache-max-size 10G \ --transfers 4 \ --verbose
Open a second terminal window and verify write access:
touch ~/mnt/proton/test_file.txt ls -l ~/mnt/proton/test_file.txt
If successful, unmount the drive using fusermount -u ~/mnt/proton and proceed to automation.
Step 3: Automating with Systemd
Relying on a terminal session or a detached screen for your mount is not production-ready. We will create a user-level systemd unit to handle the mount process, manage restarts, and ensure the drive is available at login.
Creating the Unit File
Create the directory structure for user services if it doesn't exist:
mkdir -p ~/.config/systemd/user/
Create a file named rclone-proton.service inside that directory:
# ~/.config/systemd/user/rclone-proton.service [Unit] Description=Rclone Mount for Proton Drive Documentation=http://rclone.org/docs/ After=network-online.target Wants=network-online.target [Service] Type=notify ExecStart=/usr/bin/rclone mount proton: %h/mnt/proton \ --vfs-cache-mode full \ --vfs-cache-max-size 20G \ --vfs-cache-max-age 24h \ --bwlimit-file 16M \ --dir-cache-time 60m \ --log-level INFO \ --log-file %h/rclone-proton.log ExecStop=/bin/fusermount -u %h/mnt/proton Restart=on-failure RestartSec=10 [Install] WantedBy=default.target
Expert Note: We use %h in the unit file, which systemd expands to the user's home directory. This makes the script portable across different user environments.
Enabling the Service
Reload the systemd daemon and enable the service:
systemctl --user daemon-reload systemctl --user enable --now rclone-proton
Check the status to ensure the process is active:
systemctl --user status rclone-proton
Performance Tuning Best Practices
When you mount Proton Drive via FUSE, latency is your enemy. Here is how to optimize the experience:
1. VFS Cache Mode
Always use --vfs-cache-mode full. This caches both reads and writes.
- Pros: High reliability, supports random access (required for opening PDFs, database files, etc.).
- Cons: Uses local disk space.
2. Directory Caching
The flag --dir-cache-time controls how long rclone trusts its listing of the directory before checking the remote again. Increasing this to 60m (as shown in the systemd unit) significantly speeds up file browsing (ls, file managers) but means changes made on other devices might take an hour to appear locally.
3. Bandwidth Limiting
Proton Drive is encrypted. Heavy uploads can spike CPU usage due to encryption overhead. Use --bwlimit if you notice your system becoming sluggish during large syncs.
Frequently Asked Questions (FAQ)
Does Proton Drive support Linux officially?
As of late 2025, Proton has not released a native GUI client/daemon for Linux. Rclone remains the industry-standard workaround endorsed by the community.
Why is my mount slow when listing files?
This is usually due to the encryption overhead and API latency. Ensure you are using --dir-cache-time. Also, avoid opening folders containing thousands of files in a GUI file manager, as it attempts to generate thumbnails for every file, triggering massive download requests.
Is it safe to store the rclone config file?
The rclone.conf file contains tokens that grant access to your drive. You should secure it by encrypting the configuration file itself using rclone's built-in configuration encryption features, or ensure strictly limited file permissions (chmod 600 ~/.config/rclone/rclone.conf).
Conclusion
You have successfully bridged the gap between the secure Proton ecosystem and your Linux workstation. By using rclone to mount Proton Drive, you gain the ability to interact with your encrypted cloud storage using standard Linux tools. With the systemd integration provided above, your mount is now resilient, persistent, and tuned for performance.
