+# "backend" specifies the backend used to get files modification.
+# Available options are "pyinotify", "gamin", "polling", "systemd" and "auto".
+# This option can be overridden in each jail as well.
+#
+# pyinotify: requires pyinotify (a file alteration monitor) to be installed.
+#              If pyinotify is not installed, Fail2ban will use auto.
+# gamin:     requires Gamin (a file alteration monitor) to be installed.
+#              If Gamin is not installed, Fail2ban will use auto.
+# polling:   uses a polling algorithm which does not require external libraries.
+# systemd:   uses systemd python library to access the systemd journal.
+#              Specifying "logpath" is not valid for this backend.
+#              See "journalmatch" in the jails associated filter config
+# auto:      will try to use the following backends, in order:
+#              pyinotify, gamin, polling.
+#
+# Note: if systemd backend is chosen as the default but you enable a jail
+#       for which logs are present only in its own log files, specify some other
+#       backend for that jail (e.g. polling) and provide empty value for
