Best cloud storage services with CLI for SELKS: (Comparison)

Introduction

SELKS (Suricata Embedded Linux Kernel Sensor) is a specialized Debian-based security distribution tailored to monitoring and threat detection. In environments where data confidentiality and seamless backups are critical, integrating a reliable cloud storage solution with robust CLI support becomes a must. This article presents the best cloud storage services offering native or community-driven CLI tools on Linux SELKS, compares their features, guides you through setup and common pitfalls, and helps you choose the right one for your needs.

Top Recommendations for SELKS

• pCloud – Strong encryption, user-friendly CLI, zero-knowledge optional.
• MEGA – End-to-end encrypted, generous free plan, official mega-cmd.
• Proton Drive – High privacy standards, beta CLI support.
• Filen – Swiss-hosted, zero-knowledge, active CLI community.
• Tresorit – Enterprise-grade security, encrypted CLI client.
• Icedrive – Modern UI, Twofish encryption, CLI in early development.
• Dropbox – Mature, third-party scripts (Dropbox-Uploader).
• Google Drive – Ubiquitous, community CLI gdrive.
• OneDrive – Integrated with Microsoft, open-source onedrive client.

Feature Comparison

Which One to Choose?

Your selection depends on priorities:

• Privacy-first: MEGA, Proton Drive, Tresorit, Filen.
• Balance of price and space: pCloud, Icedrive.
• Ubiquity ecosystem: Google Drive, Dropbox, OneDrive.
• Enterprise features: Tresorit, Proton Business, MEGA Enterprise.

For a SELKS server where CLI scripts automate backups, pCloud and MEGA stand out for stability. For military-grade confidentiality, Tresorit or Proton Drive are best.

CLI Setup Usage

pCloud (pcloudcc)

Official pCloud CLI daemon for Linux. Supports mount, sync and upload/download.

Installation:

wget https://downloads.pcloud.com/linux/pcloudcc_amd64.deb
sudo dpkg -i pcloudcc_amd64.deb
sudo apt-get install -f

Authentication:

pcloudcc -u you@example.com -p YourPassword

Mount pCloud as filesystem:

mkdir ~/pcloud
pcloudcc -m ~/pcloud

Common issues:
If “pcloudcc: command not found” appears, add /usr/bin to your PATH or check installation logs. For FUSE errors, install fuse package.

MEGA (mega-cmd)

Strong encryption with official CLI.

Installation:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6D2D1F8C
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 basic commands:

mega-login you@example.com YourPassword
mega-mkdir /Root/backup
mega-put /var/log /Root/backup
mega-sync /var/log /Root/log_backup

Typical pitfalls:
If “error: ENOSPC” occurs, free up /tmp or specify MEGA_TMP with --local-tmpdir. Login timeouts require adjusting megacmd config at ~/.megaCmd/mega-cmd-server.config.

Proton Drive (community CLI)

The official CLI is in beta community wrappers exist.

Installation (community tool proton-drive-cli):

sudo apt install python3-pip
pip3 install proton-drive-cli

Authenticate and upload:

proton-drive login
proton-drive upload /etc configuration_backup

Issues: Two-factor once enforced may break login – use --2fa-code flag. Watch out for API rate-limits: batch uploads under 100 files.

Filen (community script)

Zero-knowledge cloud from Switzerland. No official CLI but active community.

git clone https://github.com/FilenCommunity/filen-cli.git
cd filen-cli
sudo bash install.sh
filen-cli login
filen-cli sync ./data /remote/data

Problems: Script may require nodejs v14. If upload stalls, restart with verbose flag -v.

Tresorit (tresorit-cli)

Enterprise-grade end-to-end encryption.

curl -fsSL https://apt.tresorit.com/install.sh  sudo bash
sudo apt install tresorit-cli

tresorit-cli login
tresorit-cli list
tresorit-cli sync ./project-folder MyTresor/Project

Watch out for outdated FUSE on Debian–based systems: install libfuse2. Permission denied errors often stem from missing fuse group membership.

Icedrive (alpha CLI)

Lightweight, uses Twofish encryption. CLI in alpha stage.

wget https://github.com/Icedrive/icedrive-cli/releases/download/v0.0.1/icedrive-linux-x64.tar.gz
tar xzf icedrive-linux-x64.tar.gz
sudo mv icedrive /usr/local/bin/
icedrive login
icedrive mount ~/icedrive

Frequent issues: Alpha may crash on large transfers. Use --no-progress to reduce stdout buffering. Unmount with fusermount -u ~/icedrive.

Dropbox (Dropbox-Uploader)

Unofficial, Bash-based uploader.

git clone https://github.com/andreafabrizi/Dropbox-Uploader.git
cd Dropbox-Uploader
./dropbox_uploader.sh

Follow interactive OAuth. Usage:

./dropbox_uploader.sh upload /var/log/syslog syslogs/

OAuth tokens expire refresh with ./dropbox_uploader.sh unlink then login again.

Google Drive (gdrive)

Unofficial Go-based CLI.

wget -O gdrive https://github.com/prasmussen/gdrive/releases/download/2.1.0/gdrive-linux-x64
chmod  x gdrive
sudo mv gdrive /usr/local/bin/
gdrive about

First run opens browser for OAuth. Common error “cannot find token” means ~/.gdrive is unreadable.

OneDrive (onedrive client)

Community client with sync support.

sudo apt install onedrive
onedrive

Follow URL to authorize. Sync command:

onedrive --synchronize --verbose

Rate-limit errors can be mitigated by adding --resync every 24 hours in a cron job.

Conclusion

For security-focused SELKS deployments requiring stable CLI tools, pCloud and MEGA are top picks. If zero-knowledge is non-negotiable, weigh in Tresorit or Proton Drive. When wider ecosystem integration matters, Google Drive and Dropbox remain viable. Always test CLI clients in a staging environment to iron out FUSE, API, and OAuth quirks before rolling out automated backups in production.
