FTP Server

The FTP integration allows SonicSaaS to store device configuration backups on an external FTP server and to stage firmware files for deployment.

What It Provides

  • External backup storage — push encrypted configuration backups to an FTP server for additional redundancy
  • Firmware staging — upload firmware images to an FTP server for device retrieval during updates
  • Multiple servers — configure different FTP servers for different purposes or organizations

Setup

To configure an FTP server:

  1. Navigate to Integrations → FTP
  2. Enter the FTP server address, port, username, and password
  3. Specify the target directory for backups and/or firmware
  4. Test the connection
  5. Save the configuration

Your FTP server password is encrypted at rest using AES-256-GCM.

Backup Storage

When FTP is configured as a backup destination, device configuration backups are pushed to the FTP server after being encrypted. The files on the FTP server are already AES-256-GCM encrypted — even if the FTP server is compromised, backup contents are protected.

Firmware Staging

For firmware updates, the platform can upload firmware images to the FTP server. SonicWall Gen 6 devices can then retrieve the firmware via FTP, which is useful for environments where direct upload isn’t practical.

The platform uses a semaphore to limit concurrent FTP operations, preventing FTP server overload during fleet-wide operations.

Network Considerations

FTP connections use plaintext FTP (not FTPS). This is acceptable for LAN-only FTP servers serving Gen 6 appliances. Ensure your FTP server is on the same network as the managed devices.
