Best cloud storage services with CLI for ROSA: (Tutorial)

Introduction

ROSA Linux users often seek a reliable, secure and scriptable way to manage cloud storage. Command-line interfaces (CLIs) provide automation, integration with shell scripts and remote server workflows. In this article we review six leading cloud services—pCloud, MEGA, Proton Drive, Filen, Tresorit and Icedrive—plus two additional popular options: Dropbox and Google Drive. For each we discuss CLI tools, installation on ROSA, usage examples and common pitfalls.

Top Recommendations for ROSA Linux

When choosing a cloud-CLI on ROSA, consider:

Package availability (RPM/AppImage/Snap)
Official vs. third-party CLI support
Encryption at rest and in transit
Free tier quotas and paid plans
Integration with rclone or native binary

Overall, pCloud and MEGA stand out for native CLI support, while Proton Drive and Icedrive excel in zero-knowledge encryption via rclone. Dropbox and Google Drive benefit from mature community CLIs.

Comparison Table

Service	Free Tier	CLI Tool	Encryption	Link
pCloud	10 GB (up to 20 GB via referrals)	pcloudcc	Client-side optional	https://www.pcloud.com
MEGA	20 GB (with bonus)	megacmd	End-to-end	https://mega.nz
Proton Drive	1 GB	rclone	End-to-end	https://proton.me/drive
Filen	5 GB	filen-cli	Zero-knowledge	https://filen.io
Tresorit	3 GB trial	tresorit-cli	End-to-end	https://tresorit.com
Icedrive	10 GB	rclone	Client-side	https://icedrive.net
Dropbox	2 GB	dropbox-uploader / rclone	Transit	https://dropbox.com
Google Drive	15 GB	gdrive / rclone	Transit	https://drive.google.com

Which One to Choose?

If you need large free space and official CLI: MEGA or pCloud.
For strict zero-knowledge encryption: Proton Drive, Filen or Icedrive via rclone.
For interoperability with many providers: rclone supports Proton Drive, Icedrive, Google Drive and more.
If you run scripts in CI/CD: native CLIs (pcloudcc, megacmd) avoid OAuth overhead.
For business compliance (GDPR, HIPAA): Tresorit offers advanced policies.

Installing and Using Each CLI on ROSA

1. pCloud (pcloudcc)

pcloudcc is the official daemon CLI client. Install via RPM:

sudo dnf install https://downloads.pcloud.com/pcloudcc/pcloudcc_2.2.3.0_arm64.rpm

Authenticate and mount:

pcloudcc --login user@example.com --password YourPassword
pcloudcc --mount /mnt/pcloud

2. MEGA (megacmd)

MEGAcmd provides a rich CLI. RPM package:

sudo dnf install https://mega.nz/linux/MEGAsync/RPM/megacmd-x86_64.rpm

mega-login your@email.com YourPassword
mega-sync /home/user/Documents /Root/Documents

3. Proton Drive (via rclone)

No official CLI yet. Use rclone:

sudo dnf install rclone
rclone config
# choose new remote, name it proton, backend protondrive
# follow OAuth prompts
rclone ls proton:

4. Filen (filen-cli)

Filen offers a simple binary. Download AppImage or RPM:

wget https://github.com/filen-io/filen-cli/releases/download/v1.0.0/filen-cli-1.0.0-x86_64.AppImage
chmod  x filen-cli-1.0.0-x86_64.AppImage
./filen-cli-1.0.0-x86_64.AppImage login

Upload list:

./filen-cli list
./filen-cli upload /home/user/file.txt /remote/path/file.txt

5. Tresorit (tresorit-cli)

Install via RPM:

sudo dnf install https://download.tresorit.com/linux/tresorit.repo
sudo dnf install tresorit-cli

Authenticate and sync:

tresorit login
tresorit sync /home/user/Project tresor://Project

6. Icedrive (via rclone)

Rclone supports Icedrive:

rclone config
# new remote iced, backend icedrive
rclone ls iced:

7. Dropbox (dropbox-uploader)

Third-party bash script:

git clone https://github.com/andreafabrizi/Dropbox-Uploader.git
cd Dropbox-Uploader
chmod  x dropbox_uploader.sh
./dropbox_uploader.sh
# follow prompts to authorize
./dropbox_uploader.sh upload file.txt /

8. Google Drive (gdrive)

Community tool:

wget -O gdrive https://github.com/prasmussen/gdrive/releases/download/2.1.0/gdrive-linux-x64
chmod  x gdrive
./gdrive about
# will prompt OAuth in browser
./gdrive upload myfile.pdf

Typical Problems Solutions

Authentication errors: Ensure OAuth redirects are allowed. For CLI tools, open the URL on a browser-enabled device if the server is headless.
Missing dependencies: Use dnf install libcurl openssl or similar. Check ldd on binaries.
Mount failures: Verify FUSE is installed: dnf install fuse and add your user to fuse group.
Rate limits: Some services throttle CLI uploads—throttle your scripts or chunk large files.
Time drift: OAuth tokens may fail if system clock is off—sync with NTP: sudo dnf install chrony sudo chronyc -a makestep.

Conclusion

For ROSA Linux, the best CLI-driven cloud storage depends on your priorities: free space, encryption or official support. pCloud and MEGA score high on ease of install and native features. Proton Drive, Filen and Icedrive deliver zero-knowledge encryption via rclone. Dropbox and Google Drive remain versatile for mixed-provider workflows. Evaluate trial tiers and test typical operations—upload, download, sync—to ensure smooth integration into your shell scripts and automation pipelines.
