-### Full configuration
+## System databases

+<span class="minilink minilink-addedin">New in version 2.1.6</span> When dumping
+["all"
+databases](https://torsion.org/borgmatic/how-to/backup-your-databases/#all-databases),
+borgmatic excludes most data coming from [MariaDB system
+databases](https://mariadb.com/docs/server/reference/system-tables),
+because much of it is populated on MariaDB startup and thus not restorable (or
+just unnecessary to backup). The system data that borgmatic does include in
+these dumps are: users, roles, grants, user-defined functions, and remote
+servers.
+
+Within a Borg archive, you can find this data stored in a dump named `mysql`—the
+name of the system table this data comes from. And if you'd like to dump this
+data without having to dump "all" databases, then you can configure a database
+named `mysql` in your borgmatic configuration. For example:
+
+```yaml
+mariadb_databases:
+    - name: mysql
+```
+
+Even in this case though, only the subset of system data described above is
+included in the dump.
+
+<span class="minilink minilink-addedin">Prior to version 2.1.6</span> Dumps of
+"all" databases excluded system databases and all of their data. Additionally,
+explicitly dumping `mysql` was treated like any other database—and thus wasn't
+easily restorable.
