Back up to WebDAV
Stratum does not have permission to access the Internet and does not implement any Cloud sync functionality.
If you wish to save your Stratum backups to a WebDAV server, the "Auto Backup" can be used in conjunction with DAVx5 to enable this.
DAVx5 is a FOSS WebDAV tool that allows you to synchronise contacts, calendars, TODO lists and, allows you to create WebDAV mounts.
DAVx5 can be downloaded using any of the official channels (Google Play, F-Droid, etc.):

Open DAVx5 and open the menu, go to the "WebDAV mounts" page.
Step up the mount using your WebDAV server information and credentials.
In Stratum, open the settings and select "Auto Backup". Select a backup location and in the file menu, there will a WebDAV mount entry. Select the desired folder, choose "Use This Folder", and allow permission to access files.
Enable auto backups with the location and password of your choice. Stratum will automatically write backup files when important changes are made. DAVx5 will be notified of a new file, and will synchronise it with your WebDAV server.
