Comparison Table

Which One to Choose?

• Privacy-first: Mega, Proton Drive, Tresorit or Filen (all zero-knowledge).
• Budget-conscious: Backblaze B2 or Icedrive for low per-GB costs.
• Scripting automation: Any CLI tool fits, though AWS S3/Wasabi via awscli is ubiquitous.
• Tight integration: pCloud and Mega have mature CLI clients with built-in FUSE mount support.
• Enterprise scale: Amazon S3, Backblaze B2, Wasabi.

Installing and Using Each CLI on RancherOS

RancherOS uses Docker containers for system services. You can run CLI tools inside a container or install static binaries on the host. Below are representative steps.

pCloud (pcloudcc)

pCloud offers a FUSE-based client named pcloudcc.

# Download, extract and install
curl -L https://download.pcloud.com/cli/pcloudcc_linux.zip -o pcloud.zip
unzip pcloud.zip
chmod  x pcloudcc
mv pcloudcc /usr/local/bin/

# Authenticate
pcloudcc -u you@example.com -p YourPassword

# Mount at /mnt/pcloud
pcloudcc -u you@example.com -p YourPassword -m /mnt/pcloud

Mega (mega-cmd)

# Install via package
docker run --rm --entrypoint bash ubuntu:20.04 -c 
apt-get update  
apt-get install -y wget unzip fuse libfuse2 
wget https://mega.nz/linux/MEGAcmd-xUbuntu_20.04_amd64.deb 
dpkg -i MEGAcmd.deb


# Or on host (if Debian-based)
apt-get install megacmd

# Usage examples
mega-login you@example.com YourPassword
mega-sync /home/user/data /Root/data
mega-put backup.tar.gz /Root/backup/
mega-get /Root/report.pdf .

Proton Drive (proton-drive-cli)

# Install via pip
pip3 install proton-drive-cli

# Authenticate
proton-drive login

# Upload / download
proton-drive upload ./file.txt MyDrive/file.txt
proton-drive download MyDrive/file.txt ./file.txt

Filen (filen-cli)

# Download from GitHub
curl -sL https://github.com/filen-io/filen-cli/releases/latest/download/filen-linux -o filen
chmod  x filen
mv filen /usr/local/bin/

# Login and usage
filen login
filen upload /etc/config.conf /root/config.conf
filen list
filen download /root/config.conf .

Tresorit (tresorit-cli)

# Download installer
curl -sL https://download.tresorit.com/linux/cli/tresorit-cli.deb -o tresorit.deb
dpkg -i tresorit.deb

# Initialize and login
tresorit init
tresorit login

# Sync a folder
tresorit sync --local-folder /srv/data --tresor MyTresor

Icedrive (icedrive-cli)

# Install via npm
npm install -g icedrive-cli

# Or download binary from releases
# Then login
icedrive login

# Commands
icedrive upload data.tar.gz /data/data.tar.gz
icedrive download /data/report.pdf .

Amazon S3 (awscli)

# Install
pip3 install awscli

# Configure
aws configure

# Upload  download
aws s3 cp ./file.txt s3://mybucket/file.txt
aws s3 sync /srv/data s3://mybucket/data

Backblaze B2 (b2 CLI)

# Install via pip
pip3 install b2

# Authorize
b2 authorize-account YourAccountId YourApplicationKey

# Upload  download
b2 upload-file my-bucket local.txt remote.txt
b2 download-file-by-name my-bucket remote.txt ./local.txt

Wasabi (using awscli)

# Configure AWS CLI with Wasabi endpoint
aws configure set default.s3.endpoint_url https://s3.us-west-1.wasabisys.com
aws configure set aws_access_key_id YOUR_KEY
aws configure set aws_secret_access_key YOUR_SECRET

# Use as S3
aws s3 cp backup.tar.gz s3://my‐wasabi‐bucket/backup.tar.gz

Typical Problems and Troubleshooting

• FUSE mount fails: Ensure fuse and fusermount are installed, and the user is in the “fuse” group.
• Authentication errors: Double-check credentials some tools require an application key rather than a password.
• Container isolation: When running in a container, mount host directories (-v /mnt/data:/data) or use --privileged for FUSE.
• SSL/TLS issues: Update CA certificates (ca-certificates package) if clients complain about certificate validation.
• Rate limits / throttling: Break large uploads into chunks or add retry logic in scripts.

Conclusion

For minimal RancherOS environments, CLI cloud storage clients deliver efficiency, scriptability and low resource usage. Choose a service based on privacy, budget and feature set. With the examples above, you can install, authenticate and synchronize data quickly. Troubleshoot common issues by ensuring dependencies are met and containers have proper privileges. Whether you need zero-knowledge encryption or enterprise-grade scalability, there’s a CLI tool ready to integrate into your RancherOS workflows.
