### File upload
+#### File storage backend
+
+Set the backend used by Friendica to store uploaded file data.
+Two storage backends are available with Friendica:
+
+- **Database** : Data is stored in a dedicated table in database (`storage`)
+- **Filesystem** : Data is stored as file on the filesystem.
+
+More storage backends can be available from third-party addons.
+If you use those, please refer to the documentation of those addons for further information.
+
+Default value is 'Database (legacy)': it's the legacy way used to store data directly in database.
+
+Existing data can be moved to the current active backend using the ['storage move' console command](help/tools)
+
+If selected backend has configurable options, new fields are shown here.
+
+##### Filesystem: Storage base path
+
+The base path where Filesystem storage backend saves data.
+
+For maximum security, this path should be outside the folder tree served by the web server: this way files can't be downloaded bypassing the privacy checks.
+
+Default value is `storage`, that is the `storage` folder in Friendica code root folder.

#### Allow Users to set remote_self
-If you enable the `Allow Users to set remote_self` users can select Atom feeds from their contact list being their *remote self* in the advanced contact settings.
+If you enable the `Allow Users to set remote_self` users can select Atom feeds from their contact list being their *remote self* in the contact settings.
Which means that postings by the remote self are automatically reposted by Friendica in their names.
This feature can be used to let the user mirror e.g. blog postings into their Friendica postings.
The process does check the available system resources before creating a new worker for a task.
Because of this, it may happen that the maximum number of worker processes you allow will not be reached.
-If your server setup does not allow you to use the `proc_open` function of PHP, please disable it in this section.
-
The tasks for the background process have priorities.
To guarantee that important tasks are executed even though the system has a lot of work to do, it is useful to enable the *fastlane*.
-Should you not be able to run a cron job on your server, you can also activate the *frontend* worker.
-If you have done so, you can call `example.com/worker` (replace example.com with your actual domain name) on a regular basis from an external service.
-This will then trigger the execution of the background process.
