Service Setup and CLI Usage

1. pCloud

pCloud offers a native daemon pcloudcc for Linux. The RPM package installs cleanly on RHEL.

Installation:

sudo yum install https://download.pcloud.com/pcloudcc.rpm

Login and mount:

pcloudcc -u your_email@example.com -p YourPassword
pcloudcc --mountpoint /mnt/pcloud

Typical issues:

• Permissions: ensure /mnt/pcloud is writable by your user or group.
• SELinux: if mount fails, try setenforce 0 to test, then adjust policies.

2. Mega

mega-cmd is Mega’s official CLI suite. It provides an interactive shell plus background sync daemon.

Installation via EPEL or direct RPM:

sudo yum install epel-release
sudo yum install https://mega.nz/linux/MEGAsync/RHEL_8/x86_64/megacmd-1.10.0-1.el8.x86_64.rpm

Login and basic commands:

mega-login your_email@example.com YourPassword
mega-mkdir /Root/Backup
mega-put file.txt /Root/Backup
mega-get /Root/Backup/file.txt .

Typical issues:

• Connection timeouts: adjust --no-ssl flag or check firewall.
• Sync conflicts: use distinct folders or versioning options.

3. Proton Drive

Proton Drive CLI (proton-drive-cli) is community-maintained but works well on RHEL with Python.

Installation:

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

Authenticate and upload:

proton-drive login
proton-drive upload /path/to/local.file /Drive/Folder/
proton-drive download /Drive/Folder/remote.file .

Typical issues:

• 2FA prompts: complete web-based login, then reauthorize CLI.
• Dependency errors: ensure python3-requests and keyring are installed.

4. Filen

Filen CLI is a Python tool available via PyPI.

sudo yum install python3-pip
pip3 install filen-cli

Usage:

filen login your_email@example.com
filen upload local.txt /remote/folder/
filen download /remote/folder/remote.txt .

Typical issues:

• Login failures: check time synchronization on your server.
• Slow transfers: try using --parallel N for multiple threads.

5. Tresorit

Tresorit CLI (tresorit-cli) provides secure end-to-end encrypted storage. Official RPM is available.

sudo yum install https://download.tresorit.com/linux/rpm/tresorit-cli.rpm

Login and sync:

tresorit-cli auth login
tresorit-cli sync /local/folder tresor://MyTresor

Typical issues:

• Authentication timeouts: ensure you have a stable internet connection and open ports 443/80.
• Sync errors: check file path length, Tresorit enforces

6. Icedrive

Icedrive CLI (icedrive-cli) uses a single binary for upload/download and mount.

curl -LO https://downloads.icedrive.net/client/icedrive-cli-linux-amd64
chmod  x icedrive-cli-linux-amd64
sudo mv icedrive-cli-linux-amd64 /usr/local/bin/icedrive

Login and mount:

icedrive login your_token_here
icedrive mount /mnt/ice

Typical issues:

• FUSE errors: install fuse-sshfs and ensure fuse is loaded.
• Token refresh: obtain a new token from the web dashboard.

7. Backblaze B2

The official B2 CLI is a Python utility b2.

sudo yum install python3-pip
pip3 install b2

Authorize and sync:

b2 authorize-account YOUR_KEY_ID YOUR_APP_KEY
b2 sync /local/data b2://my-bucket/data

Typical issues:

• Authorization errors: double-check key and region (bin --endpoint if needed).
• Large file uploads: use --large-file-chunk=150M for better parallelism.

8. Amazon S3

AWS CLI is the de facto standard for S3. Available as an RPM in the EPEL repository.

sudo yum install epel-release
sudo yum install awscli

Configure and copy:

aws configure
aws s3 cp local.file s3://my-bucket/remote.file
aws s3 sync /local/folder s3://my-bucket/folder

Typical issues:

• Permission denied: attach correct IAM policy to your access keys.
• Region mismatch: specify --region us-east-1 if different from default.

Which One to Choose?

• If privacy and zero-knowledge encryption are paramount, consider pCloud, Mega, or Proton Drive.
• For enterprise compliance and granular control, Tresorit excels at secure sharing and auditing.
• On a tight budget or high-volume backups, Backblaze B2 and Amazon S3 offer pay-as-you-go object storage.
• If you prefer a mountable drive with FUSE, Icedrive and pCloud provide seamless mount options.

Conclusion

Red Hat Enterprise Linux environments benefit from reliable CLI cloud tools that integrate with automation, scripts, and CI/CD pipelines. Evaluate your needs—privacy, performance, compliance, or price—and select the provider that best aligns. With clear installation steps, usage examples, and known issue workarounds, you can confidently deploy any of these cloud storage solutions on RHEL.
