If you have a central server which is performing backups, and the client computer trusts the server, use syncthing to mirror the files on the client to the server. Syncthing also has an android client.
If the client computer doesn't trust the server, for example you are offering a backup destination for friends or extended family, then use duplicati for incremental encrypted backups.
Both options work on both linux and windows.
