+# seconds, not sure exactly how long) then the server will give up and

+# on the server and TLSReadFailed or TLSWriteFailed errors on the client.
+# Also, some firewalls and NAT gateways will kill idle connections after
+# similar lengths of time. 
+#
+# This can happen for example when most files are backed up already and
+# don't need to be sent to the store again, while scanning a large
+# directory, or while calculating diffs of a large file. To avoid this,
+# KeepAliveTime specifies that special keep-alive messages should be sent
+# when the connection is otherwise idle for a certain length of time,
+# specified here in seconds.

+# The default is that these messages are never sent, equivalent to setting
+# this option to zero, but we recommend that all users enable this.
