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

Introduction

In modern workflows, having reliable cloud storage with a command-line interface (CLI) is essential, especially on Linux and ReactOS environments where graphical clients may be limited or unavailable. This article reviews the top services—pCloud, MEGA, Proton Drive, Filen, Tresorit, Icedrive—and a few additional recommendations. We cover key features, CLI installation and usage, typical issues, and help you decide which solution best fits your needs.

Top Recommendations

• pCloud – Great balance of price, security, and native CLI on Linux.
• MEGA – Large free tier unofficial clients on ReactOS.
• Proton Drive – Zero-knowledge encryption CLI via third-party tools.
• Filen – Privacy-focused community-maintained CLI.
• Tresorit – Enterprise-grade encryption official CLI beta.
• Icedrive – Pulse-width encryption Linux CLI FUSE mount.
• Dropbox – Mature ecosystem strong ReactOS support via Win32 client.
• Google Drive – Powerful API use rclone for CLI.

Comparison Table

How to Choose

• Privacy and Encryption: Choose Proton Drive, Filen, Tresorit, or Icedrive for zero-knowledge security.
• Free Storage: MEGA (20 GB) and Google Drive (15 GB) lead the pack.
• Cross-Platform CLI: pCloud and MEGA have mature official clients Dropbox works well on ReactOS.
• Enterprise Use: Tresorit and AWS S3 for compliance and scalability.

Service Setup and CLI Usage

1. pCloud

Official CLI for Linux, install via DEB/RPM or compile from source.

# Debian/Ubuntu
wget https://downloads.pcloud.com/pcloudcmd_2.11.5_amd64.deb
sudo dpkg -i pcloudcmd_2.11.5_amd64.deb
# Authenticate
pcloudcc --login your-email@example.com
pcloudcc --passwd yourpassword
# Sync a folder
pcloudcc --sync /home/user/Photos /Photos

Typical Issues:

• “Cannot connect” if port 443 is blocked.
• Permissions errors—run with proper user privileges.

2. MEGA

MEGAcmd is the official CLI, cross-platform via package or Homebrew.

# Ubuntu
sudo apt install wget gnupg
wget -O - https://mega.nz/keys/MEGA_signing.key  sudo apt-key add -
echo deb https://mega.nz/linux/MEGAsync/xUbuntu_(lsb_release -rs) ./  sudo tee /etc/apt/sources.list.d/mega.list
sudo apt update  sudo apt install megacmd
# Login and list files
mega-login user@domain.com password
mega-ls /
mega-put localfile.txt /Backup

Typical Issues:

• Rate limiting on free accounts.
• SSL errors—ensure CA certificates are up to date.

3. Proton Drive

Use unofficial proton-drive-cli.

# Install via pip
pip3 install proton-drive-cli
# Authenticate
proton-drive-cli login
# Upload a file
proton-drive-cli upload document.pdf
# List folder
proton-drive-cli list

Typical Issues:

• OAuth token expiration—re-login periodically.
• API rate limits on free tier.

4. Filen

Community CLI requires Go runtime.

go install github.com/Jerem25/filen-cli@latest
# Set API key
export FILEN_API_KEY=your_api_key
# Upload
filen-cli upload /path/to/file
# Download
filen-cli download file_id

Typical Issues:

• Infrequent updates—check GitHub repo.
• Authentication errors if API key misconfigured.

5. Tresorit

Beta CLI request access from support.

sudo apt install tresorit-cli
tresorit login
tresorit ls
tresorit sync ~/tresor /MyTresor

Typical Issues:

• Beta features—expect minor bugs.
• Large file sync may hang split files if needed.

6. Icedrive

Official CLI and FUSE mount.

# Download binary
wget https://github.com/Icedrive/icedrive-linux/releases/download/v1.1.8/icedrive-linux.zip
unzip icedrive-linux.zip
sudo mv icedrive /usr/local/bin/
# Login and mount
icedrive login you@example.com
icedrive mount ~/mnt/icedrive
# Sync
rsync -av ~/Project ~/mnt/icedrive/Backups/

Typical Issues:

• FUSE permission errors—ensure user in fuse group.
• Stale mount unmount with fusermount -u.

7. Dropbox

Official Linux CLI headless mode. On ReactOS use the Windows installer.

# Ubuntu
sudo apt install dropbox python3-gpg
dropbox start -i
# After installation, get link and paste for auth
dropbox stop
dropbox start -i
# CLI commands
dropbox status
dropbox exclude add ~/Videos

Typical Issues:

• dbclient segfault—install matching Python GPG.
• Sync loops—exclude large temp files.

8. Google Drive via rclone

Rclone supports many backends including Google Drive.

# Install
curl https://rclone.org/install.sh  sudo bash
# Configure remote
rclone config
# Example commands
rclone copy ~/Docs remote:Backups
rclone mount remote: ~/gdrive --vfs-cache-mode writes

Typical Issues:

• OAuth consent screen—use service accounts for automation.
• Rate limits—use --drive-chunk-size tuning.

9. AWS S3

The AWS CLI is robust and handles S3 transfers.

# Install
curl https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip -o awscliv2.zip
unzip awscliv2.zip
sudo ./aws/install
# Configure
aws configure
# Basic commands
aws s3 ls s3://my-bucket
aws s3 sync ~/SiteBackup s3://my-bucket/backup --delete

Typical Issues:

• Permission denied—check IAM policies.
• Connection timeouts—configure retry settings.

Conclusion

Choosing the right CLI-based cloud storage depends on your priorities: security, free space, platform compatibility, or enterprise features. pCloud and MEGA are excellent for general use on Linux Dropbox offers the best ReactOS compatibility. Privacy buffs should consider Proton Drive, Filen, Tresorit or Icedrive. For automation and scale, rclone with Google Drive or AWS S3 is unbeatable. Evaluate your workflow and constraints, test the free tiers, and adopt the one that balances convenience, security, and cost.
