+=====================
+ Database Limit Size
+=====================
+
+This module allows blocking backend access when database limit is exceeded
+
+On loading backend page, module fetches size of database (including filestore) and compares it with value, that
+is defined in "System Parameters" as ``database_limit_size``. Value is expected to be in bytes.
+
+If ``database_limit_size`` is not given or zero, there is no limit.
