Installing and Configuring CLI Tools
1. pCloud (pcloudcc)
apt-get update apt-get install git build-essential libcurl4-openssl-dev git clone https://github.com/pcloudcom/console-client.git cd console-client ./install.sh pcloudcc --help
Typical issues: missing libssl-dev resolve via apt-get install libssl-dev.
2. MEGA (megatools)
apt-get update apt-get install megatools megatools --help
Login:
megatools login --username you@domain.com --password YOUR_PASS
Common error “Failed to init curl”: install libcurl4.
3. Proton Drive (proton-drive-cli)
apt-get install python3-pip pip3 install proton-drive-cli proton-drive login
Note: follow OAuth flow in browser. For headless servers, generate a token locally and copy.
4. Filen (filen-cli)
wget https://github.com/filen-io/filen-cli/releases/download/v1.0.0/filen-cli_1.0.0_amd64.deb dpkg -i filen-cli_1.0.0_amd64.deb filen login
Ensure apt-get -f install to fix dependencies.
5. Tresorit (tresorit-cli)
curl -s https://apt.tresorit.com/tresorit.asc apt-key add - echo deb https://apt.tresorit.com/ stable main tee /etc/apt/sources.list.d/tresorit.list apt-get update apt-get install tresorit-cli tresorit-cli login
If “gpg: keyserver unreachable”, switch to a public keyserver.
6. Icedrive (icedrive-cli)
apt-get install nodejs npm npm install -g icedrive-cli icedrive login
Watch for Node version compatibility use Node 14 .
7. Backblaze B2 (b2 CLI)
apt-get install python3-pip pip3 install b2 b2 authorize-account ACCOUNT_ID APP_KEY
Tip: export credentials in ~/.b2_account_info.
8. Amazon S3 (awscli)
apt-get update apt-get install awscli aws configure
Ensure you set region, access key and secret. Use aws s3 cp or sync.
Common Problems Troubleshooting
- Authentication Failures: Check clock skew on UTM sync with NTP.
- Missing Dependencies: Review error logs and install required dev libraries (e.g., libssl-dev, libcurl4).
- Certificate Errors: Update CA bundle:
apt-get install ca-certificates. - Network Timeouts: Verify proxy settings or open firewall ports (TCP 443).
- Permission Denied: Run CLI as root or adjust file system permissions.
Conclusion
Integrating cloud storage with Sophos UTM via CLI empowers administrators with automated backups, off-site retention and enhanced disaster recovery. Choose end-to-end encrypted services like MEGA or Proton Drive for sensitive data, or leverage S3-compatible solutions such as Backblaze B2 for cost-efficient, scalable options. Follow the installation guides, mind common pitfalls, and secure your logs and backups seamlessly in the cloud.
