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

Introduction

When running an EasyNAS-based Linux file server, integrating cloud storage via CLI tools brings flexibility, automation and off-site backups. This article reviews top cloud storage providers offering robust command-line interfaces on Linux, with a focus on pCloud, MEGA, Proton Drive, Filen, Tresorit, Icedrive—and two additional recommendations, AWS S3 and Backblaze B2. You’ll find a comprehensive comparison table, selection guidance, setup examples for each CLI tool, and troubleshooting tips.

How to Choose the Right Provider

Security: If zero-knowledge end-to-end encryption is mandatory, MEGA, Proton Drive and Tresorit excel.
Budget: Backblaze B2 and AWS S3 offer low pay-as-you-go storage, ideal for large archives.
CLI Maturity: MEGA’s megacmd and AWS’s aws-cli are rock-solid newer tools like proton-drive-cli may still evolve.
Performance: Regional proximity matters choose a provider with nearby servers to your EasyNAS host.
Features: Versioning, snapshots, share links—compare feature sets before committing.

Using Each CLI on Linux EasyNAS

1. pCloud (pcloudcc)

Installation and authentication:

# Debian/Ubuntu
sudo apt install pcloudcc

# Start daemon
pcloudcc --daemon-user your_user --daemon

# Authenticate
pcloudcc --auth

Typical commands:

# List files
pcloudcc --list

# Upload
pcloudcc --upload /path/to/local/file /remote/folder

# Download
pcloudcc --download /remote/file /local/path

Common issues:

Daemon fails to start: check user privileges.
“Unable to authenticate”: re-run --auth and verify network.

2. MEGA (megacmd)

Installation and login:

sudo apt install megacmd

# Start the MEGA shell
mega-login youremail@example.com YourPassword

Basic usage:

# Upload folder
mega-put /mnt/nas/data /Backup

# Sync local to remote
mega-sync /mnt/nas/data /Backup

# List
mega-ls /Backup

Typical problems:

Sync stops: update megacmd or use mega-sync with --no-progress.
Session expired: re-login or use mega-login --anonymous for public links.

3. Proton Drive (proton-drive-cli)

Install (pip method):

pip3 install proton-drive-cli

# Initialize and login
proton-drive login

Upload/download:

# Upload file
proton-drive upload /path/nas/file.txt /

# Download file
proton-drive download file.txt /local/path/

Watch out for:

Rate limits: API calls are throttled on free tiers.
Large files: may require splitting or increasing timeout flags.

4. Filen (filen-cli)

Installation and setup:

# Download latest binary
wget https://github.com/filen-io/filen-cli/releases/latest/download/filen-cli-linux-amd64
chmod  x filen-cli-linux-amd64
sudo mv filen-cli-linux-amd64 /usr/local/bin/filen

# Authenticate
filen login

Usage examples:

# List all remote directories
filen ls /

# Upload directory
filen cp -r /mnt/nas/backups /Backups

# Download
filen get /Backups -o /local/nas

Common errors:

“API key invalid”: re-login with filen login.
Transfer stalled: add --chunk-size option for large files.

5. Tresorit (tresorit-cli)

Beta CLI installation:

# Download from Tresorit (requires account)
curl -O https://download.tresorit.com/linux/cli/tresorit-cli.deb
sudo dpkg -i tresorit-cli.deb
sudo apt -f install

# Login
tresorit login

Basic commands:

# Sync local to Tresor
tresorit sync /mnt/nas/data MyTresor

# Status
tresorit status

# Share link
tresorit share MyTresor

Troubleshooting:

“Sync conflict”: manual resolution via --conflict-policy.
Memory leaks: restart tresorit daemon periodically.

6. Icedrive (icedrive)

Installation:

# Debian/Ubuntu
sudo apt install icedrive

# Initialize
icedrive login

Common operations:

# Mount as drive
icedrive mount /mnt/icedrive

# Copy file
icedrive upload /mnt/nas/file.iso /Backup

# Unmount
icedrive umount

Watch for:

Kernel dependencies for FUSE: install fuse package.
Mount failure: ensure /mnt/icedrive exists and user has access.

7. AWS S3 (aws-cli)

Install amp configure:

sudo apt install awscli

aws configure
# Enter Access Key, Secret Key, region (e.g. us-east-1)

Usage:

# Sync NAS folder to S3 bucket
aws s3 sync /mnt/nas/backups s3://my-bucket/backup

# List buckets
aws s3 ls

# Download
aws s3 cp s3://my-bucket/file.tar.gz /local/path/

Common pitfalls:

Permissions denied: check IAM policies and region mismatch.
Insufficient throughput: increase multipart chunk size via --multipart-chunk-size-mb.

8. Backblaze B2 (b2cmd)

Setup:

pip3 install b2
b2 authorize-account ACCOUNT_ID APPLICATION_KEY

Examples:

# Create bucket
b2 create-bucket my-nas-bucket allPublic

# Upload file
b2 upload-file my-nas-bucket /mnt/nas/data.tar.gz data.tar.gz

# Download file
b2 download-file-by-name my-nas-bucket data.tar.gz /local/data.tar.gz

Issues to watch:

Network errors: retry with --num-threads and --retry options.
Bucket naming conflicts: choose globally unique names.

Conclusion

For an EasyNAS Linux environment, each provider brings unique strengths: MEGA and Proton Drive for zero-knowledge encryption AWS S3 and Backblaze B2 for cost-effective scalability pCloud, Filen and Icedrive for user-friendly clients. Evaluate free tiers, CLI maturity, security and budget to select the best fit. With the provided installation steps, sample commands and troubleshooting tips, you can integrate cloud storage into your NAS workflows seamlessly.
