Which One to Choose for ClearOS?

• If you need strong end-to-end encryption and a Linux-first CLI, choose MEGA or Tresorit.
• If you prefer lifetime plans or very large free tiers, consider pCloud or Icedrive.
• For pure object storage and tight integration with backup scripts, Backblaze B2 or AWS S3 via rclone or aws-cli is ideal.
• If privacy and open-source are highest priorities, Proton Drive and Filen offer robust, open-source CLI clients.

1. pCloud

pCloud offers both client-side encryption (with the Crypto add-on) and a native daemon (pcloudcc) that can be managed via CLI.

Installation

# Enable EPEL if not already
yum install epel-release -y
# Download the RPM
wget https://www.pcloud.com/download/PCloudCLI_x86_64.rpm
# Install
yum localinstall PCloudCLI_x86_64.rpm -y

Configuration Usage

# Log in
pcloudcc -u you@example.com -p yourpassword
# Or use OAuth token
pcloudcc -t YOUR_OAUTH_TOKEN
# Mount to directory
mkdir -p ~/pcloud
pcloudcc -m ~/pcloud
# Sync local folder to cloud
pcloudcc upload ~/backup ~/pcloud/backups

Common Issues

• “Could not mount”: ensure FUSE is installed (yum install fuse-fuse-libs).
• OAuth token expired: re-run login command.

2. MEGA

MEGA provides 20 GB free, end-to-end encrypted sync and backup via megacmd.

Installation

# Add MEGA repo
rpm --import https://mega.nz/keys/MEGA_signing.key
cat  /etc/yum.repos.d/megacmd.repo
[megacmd]
name=MEGAcmd Repository
baseurl=https://megacmd.megasoftware.net/yum/el7
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mega.nz/keys/MEGA_signing.key
enabled=1
EOF
# Install
yum install megacmd -y

Usage Examples

# Log in
mega-login you@example.com yourpassword
# Upload a file
mega-put ~/report.pdf /Root/reports/
# Sync a folder
mega-sync /Root/backups ~/local_backups

Common Issues

• Sync conflicts: use mega-sync --backup or rename local files.
• Bandwidth limits: upgrade or throttle with --max-downloads.

3. Proton Drive

Proton Drive CLI (proton-drive-cli) is open-source and provides zero-knowledge encryption.

Installation

# Install via pip
yum install python3-pip -y
pip3 install proton-drive-cli

Usage Examples

# Authenticate
proton-drive-cli login
# Upload folder
proton-drive-cli upload /home/user/docs
# List files
proton-drive-cli list

Common Issues

• “Please update Proton Drive CLI”: run pip3 install --upgrade proton-drive-cli.
• Network timeouts: check /etc/hosts for Proton endpoints.

4. Filen

Filen’s CLI (filen-cli) supports encryption and fast transfers.

Installation

# Download binary
wget https://github.com/filen-io/filen-cli/releases/latest/download/filen-cli-linux-amd64.tar.gz
tar -xzf filen-cli-linux-amd64.tar.gz
mv filen-cli /usr/local/bin/

Usage Examples

# Initialize
filen-cli login
# Upload file
filen-cli upload /home/user/picture.jpg
# Download
filen-cli download picture.jpg ~/Downloads

Common Issues

• Permission denied: ensure /usr/local/bin/filen-cli is executable.
• Token expired: re-run filen-cli login.

5. Tresorit

Tresorit’s CLI (tresorit-cli) offers enterprise-grade zero-knowledge encryption.

Installation

# Add repo and install
rpm --import https://download.tresorit.com/linux/repos/tresorit_pubkey.gpg
cat  /etc/yum.repos.d/tresorit.repo
[tresorit]
name=Tresorit Repository
baseurl=https://download.tresorit.com/linux/repos/
gpgcheck=1
gpgkey=https://download.tresorit.com/linux/repos/tresorit_pubkey.gpg
enabled=1
EOF
yum install tresorit-cli -y

Usage Examples

# Authenticate
tresorit-cli auth login
# Sync folder
tresorit-cli sync ~/work /Tresorit/Work

Common Issues

• “Sync stuck”: restart service with systemctl restart tresorit.
• Rate limiting: contact support for higher API quotas.

6. Icedrive

Icedrive’s CLI (icedrive-cli) supports Drive/Proton-style encryption and WebDAV mount.

Installation

# Download and extract
wget https://github.com/Icedrive/Icedrive-CLI/releases/latest/download/IcedriveCLI_linux_amd64.tar.gz
tar -xzf IcedriveCLI_linux_amd64.tar.gz
mv icedrive /usr/local/bin/icedrive-cli
chmod  x /usr/local/bin/icedrive-cli

Usage Examples

# Login
icedrive-cli login
# List
icedrive-cli ls /
# Upload
icedrive-cli upload /home/user/file.txt /

Common Issues

• Missing dependencies: install openssl-libs.
• Mount failures: use FUSE alternative or WebDAV.

7. Backblaze B2

Backblaze B2 is cost-effective S3-compatible storage, ideal for backups and archives.

Installation

# Install B2 CLI
pip3 install b2
# Or install rclone for multi-cloud
yum install rclone -y

Usage Examples

# Using B2 CLI
b2 authorize-account YOUR_KEY_ID YOUR_APPLICATION_KEY
b2 sync ~/local_folder b2://my-bucket/backup
# Using rclone
rclone config create b2 b2 account YOUR_KEY_ID key YOUR_APP_KEY
rclone sync ~/local_folder b2:my-bucket/backup

Common Issues

• 401 Unauthorized: check key/secret.
• Large file slow: increase thread count in rclone: --transfers, --checkers.

8. Amazon S3

AWS S3 via aws-cli, s3cmd or rclone is highly scalable and globally available.

Installation

yum install awscli -y
# or
pip3 install s3cmd

Usage Examples

# aws-cli
aws configure
aws s3 cp ~/file.txt s3://mybucket/path/
# s3cmd
s3cmd --configure
s3cmd sync ~/dir/ s3://mybucket/dir/
# rclone
rclone config create myaws s3 provider AWS env_auth false access_key_id XXX secret_access_key YYY
rclone copy ~/dir/ myaws:mybucket/dir/

Common Issues

• Signature mismatch: ensure region is correct.
• Permissions denied: IAM policy may need editing.

9. Google Drive (via rclone)

Using rclone, you can mount and sync Google Drive seamlessly.

Installation

yum install rclone -y

Configuration Usage

# Configure remote
rclone config
# Follow prompts to set up drive type, client_id, secret, and OAuth
# Sync or mount
rclone sync ~/myfolder drive:Backups
# Mount (requires fusermount)
mkdir -p ~/gdrive
rclone mount drive: ~/gdrive --daemon

Common Issues

• Mount fails: install fuse-sshfs or fuse.
• Token refresh problems: re-run rclone config reconnect drive:.
