+===== Syncthing =====
+Follow our [[en:server:services:syncthing|Syncthing]] tutorial for both devices (backup server and your data device).
+==== Add device ====
+Add the backup server to your client under ''Remote Devices''.
+==== Add folder ====
+  * Add a folder under ''Folder'' and select the folder you want to backup under ''General''.
+  * Select your backup server under ''Sharing''.
+  * Under ''File Versioning'' you could add ''Staggered File Versioning'' which gives you more certainty, but have a look at https://docs.syncthing.net/users/versioning.html and choose what suits you best.
+  * Also check ''Advanced'' and ''Folder type'' and again choose what suits you best. For example, Keepass can be used with ''Send & Receive'' if you want sync your database on both devices.
