+##### Backing up / moving to another server
+
+Decided to back up your data container and/or move to another server? Here's how
+you do it:
+
+On the old server, stop your ttrss container and then do:
+
+```
+docker commit -m "Backup of XXX" <CONTAINER NAME>
+docker save <IMAGE CREATED BY COMMIT> > /tmp/<filename>.tar
+```
+
+On the new server, copy the created .tar file from the old server and 
+import the file with:
+
+```
+docker load < <filename.tar>
+```
+
+This will load the container from the .tar file into Docker's local registry.
+After that you can run that imported container again the usual way with:
+
+```
+docker run -d <IMAGE ID>
 ```
