The Proton Drive integration package for Plakar allows you to back up and restore data to and from Proton Drive cloud storage, as well as host Kloset stores directly within Proton Drive. It is built on top of Rclone, a command-line program to manage files on cloud storage, and supports Proton Drive as one of its many backends.
The Rclone integration package for Plakar provides three connectors:
| Connector type | Description |
|---|---|
| ✅ Storage connector | Host a Kloset store inside a Rclone remote. |
| ✅ Source connector | Back up a Rclone remote into a Kloset store. |
| ✅ Destination connector | Restore data from a Kloset store into a Rclone remote. |
Requirements
- Rclone must be installed, and at least one Proton Drive remote must be configured.
Typical use cases
- Cold backup of Proton Drive folders
- Long-term archiving and disaster recovery
- Portable export and vendor escape to other platforms
Installation
To interact with Proton Drive, you need to install the Rclone Plakar package. It can be installed either by downloading a pre-built package or by building it from source.
Plakar provides pre-compiled packages for common platforms. This is the simplest installation method and is suitable for most users.
Note: Installing pre-built packages requires authentication with Plakar. See Login to Plakar to unlock features.
Install the Rclone package:
$ plakar pkg add rclone
Verify the installation:
$ plakar pkg list
Building from source is useful if you cannot use pre-built packages.
Prerequisites
- A working Go toolchain compatible with your version of Plakar.
Build the Rclone package:
$ plakar pkg build rclone
On success, a package archive is generated in the current directory, for example rclone_v1.0.0_darwin_arm64.ptar.
Install the generated package:
$ plakar pkg add ./rclone_v1.0.0_darwin_arm64.ptar
Verify the installation:
$ plakar pkg list
To check whether the Rclone package is already installed:
$ plakar pkg list
To upgrade to the latest available version, remove the existing package and reinstall it:
$ plakar pkg rm rclone
$ plakar pkg add rclone
This preserves existing store, source, and destination configurations.
Generate Rclone configuration
Install Rclone on your system by following the instructions at https://rclone.org/install/.
Then, run the following command to configure Rclone with Proton Drive:
$ rclone config
You will be guided through a series of prompts to set up a new remote for Proton Drive.
For Rclone v1.72.1, the configuration flow is as follows:
- Choose
nto create a new remote. - Name the remote (e.g.,
mydrive). - Enter your credentials.
- Validate the remote configuration.
To verify that the remote is configured, run:
$ rclone config show mydrive
And to verify you have access to your Proton Drive files, run:
$ rclone ls mydrive:
The output should list the files and folders in your Proton Drive.
Connectors
The Rclone package provides storage, source, and destination connectors to interact with Proton Drive via Rclone.
You can use any combination of these connectors together with other supported Plakar connectors.
Storage connector
⚠️ See the section “Limitations and considerations” for important information about hosting Kloset stores on Proton Drive.
The Plakar Rclone package provides a storage connector to host Kloset stores on Rclone remotes.

Configure
# Import the rclone configuration as a storage configuration.
# Replace "mydrive" with your Rclone remote name.
rclone config show | plakar store import -rclone mydrive
# Initialize the Kloset store
$ plakar at @mydrive create
# List snapshots in the Kloset store
$ plakar at @mydrive ls
# Verify integrity of the Kloset store
$ plakar at @mydrive check
# Back up a local folder to the Kloset store
$ plakar at @mydrive backup /etc
# Back up a source configured in Plakar to the Kloset store
$ plakar at @mydrive backup @my_source
Options
These options can be set when configuring the storage connector with plakar store add or plakar store set:
| Option | Purpose |
|---|---|
passphrase | The Kloset store passphrase |
Source connector
The Plakar Rclone package provides a source connector to back up remote directories accessible via Rclone.

Configure
# Import the rclone configuration as a source configuration.
# Replace "mydrive" with your Rclone remote name.
rclone config show | plakar source import -rclone mydrive
# Back up the remote directory to the Kloset store on the filesystem
$ plakar at /var/backups backup @mydrive
# Or back up the remote directory to a Kloset store configured with "plakar store add"
$ plakar at @store backup @mydrive
Options
The Rclone source connector doesn’t support any specific options.
Destination connector
⚠️ See the section “Limitations and considerations” for important information about restoring to Proton Drive.
The Rclone package provides a destination connector to restore snapshots to remote directories reachable over Rclone.

Configure
# Import the rclone configuration as a destination configuration.
# Replace "mydrive" with your Rclone remote name.
rclone config show | plakar destination import -rclone mydrive
# Restore a snapshot from a filesystem-hosted Kloset store to the Rclone remote
$ plakar at /var/backups restore -to @mydrive <snapshot_id>
# Or restore a snapshot from the Kloset store configured with "plakar store add store …"
$ plakar at @store restore -to @mydrive <snapshot_id>
Options
The Rclone destination connector doesn’t support any specific options.
Limitations and considerations
- Proton Drive API has rate limits, heavy usage may require throttling.
- At the time of writing (2025-12-24), Proton Drive support is in beta in Rclone and write operations are not supported. You will be able to back up from Proton Drive, but not restore to it or host Kloset stores on it until the issue is resolved.
