Best cloud storage services with CLI for Rocks Cluster Distribution: (Guide)

Introduction

In high-performance computing environments such as a Linux Rocks Cluster Distribution, robust and scriptable cloud storage solutions are essential. Command-line interfaces (CLIs) allow seamless integration into batch jobs, automated pipelines, and cron tasks. This article reviews top cloud-storage providers offering native CLI tools, compares their features, and provides usage examples and troubleshooting tips. We cover pCloud, MEGA, Proton Drive, Filen, Tresorit, Icedrive, plus additional options like Dropbox and AWS S3.

CLI Usage and Examples

pCloud CLI (pcloudcc)

Install and authorize:

# Debian/Ubuntu
sudo apt update  sudo apt install pcloudcc

# Mount remote as filesystem (replace TOKEN)
pcloudcc --token your_pcloud_token --mountpoint ~/pcloud

Sync a folder:

rsync -avz /data/input ~/pcloud/Backup/

MEGA CLI (megacmd)

Download and login:

# Ubuntu/Debian
wget https://mega.nz/linux/MEGAsync/xUbuntu_20.04/amd64/megacmd_1.4.0-1.1_amd64.deb
sudo dpkg -i megacmd__amd64.deb

mega-login your_email your_password

Upload a directory:

mega-put /cluster/results /Root/Results

Proton Drive CLI (proton-cli)

(Beta) Install via npm:

npm install -g proton-cli
proton login your@proton.me

List and upload:

proton drive list
proton drive upload /cluster/data --path /Projects

Filen CLI (filencli)

Install and configure:

# Download binary
wget https://github.com/filenio/filencli/releases/download/v1.0.0/filencli-linux-amd64
chmod  x filencli-linux-amd64  mv filencli-linux-amd64 /usr/local/bin/filencli

filencli auth login

Upload file:

filencli upload /cluster/logs.gz /logs.gz

Tresorit CLI (tresorit-cli)

Community wrapper — install via pip:

pip install tresorit-cli
tresorit-cli login

Sync a local folder:

tresorit-cli sync start /cluster/outputs MyTresor/Outputs

Icedrive CLI (icedrive-cli)

Download and install:

wget https://github.com/Icedrive/icedrive-cli/releases/latest/download/icedrive-linux
chmod  x icedrive-linux  mv icedrive-linux /usr/local/bin/icedrive

icedrive login your_email your_password

List and upload:

icedrive ls /
icedrive cp /cluster/archive.tar /archive.tar

Dropbox CLI

Install official CLI:

sudo apt install python3-dropbox
dropbox start -i    # initial setup via GUI or manual OAuth token

Alternatively use rclone:

rclone config  # add remote “dropbox”
rclone sync /cluster/data dropbox:ClusterBackup

AWS S3 (awscli)

Install and configure:

sudo apt install awscli
aws configure    # set AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, region

Copy data:

aws s3 sync /cluster/results s3://my-rocsk-cluster-bucket/results

Which One to Choose?

• If you need simple mounting and archiving: pCloud.
• For maximum free space and built-in encryption: MEGA.
• When privacy is paramount: Proton Drive or Filen.
• Enterprise-grade confidential data: Tresorit.
• Modern, high-performance desktop integration: Icedrive.
• General-purpose scripting with broad tooling: Dropbox via rclone or AWS S3.

Consider storage quotas, encryption, pricing, and network throughput in your cluster environment.

Typical Problems and Troubleshooting

• Authentication errors: Verify tokens, API keys, and two-factor setups. Use verbose flags (e.g., --verbose).
• Network timeouts: Increase retries or adjust region endpoints for AWS S3 ensure firewall rules allow outbound TLS on port 443.
• Mount failures: Check FUSE installation, user permissions, and mountpoint existence.
• Sync conflicts: Implement consistent naming, avoid simultaneous writes, or use snapshot/versioning features.
• Rate limits: Spread requests over time or request higher quotas from provider support.

By selecting the right CLI-friendly cloud storage and following best practices, you can streamline data workflows on your Linux Rocks Cluster and ensure reliable, secure backups and file transfers.
