The Online Backup allows you to backup your Devolutions Online Drive, SQLite, and XML data sources in a safe online cloud storage. It will automatically save your sessions when you initiate a change in Remote Desktop Manager.
It is available for free in Remote Desktop Manager Free and Team Editions.
You will be able to delete your backup files from your RDM Online Services, but you will have to create the Online Backup from your Remote Desktop Manager application.
Consult Online Backup Settings - Windows Edition or Online Backup Settings - Mac Edition for more information on the configuration.
