+# I've no idea if it's complete. But at least it worked for me.
+#
+# Before using it, you have to prepare your DVD(-RAM):
+# to be a pseudo tape for amanda: It needs a file system and
+# a "data" directory.
+#
+# 1) create a file system
+#    e.g. mkudffs --vid=<LABEL> --media-type=dvdram --utf8 <DEVICE>
+# 2) mount <DEVICE> <MOUNTPOINT>
+# 3) mkdir <MOUNTPOINT>/data
+# 4) umount
+#
+# ## amanda.conf:
+# changerdev=<your dvd-ram>
+# tapedev=file:<mountpoint>
+#
+# ## sudoers.conf
+# backup  ALL = (root) NOPASSWD: /bin/mount, /bin/umount, /usr/bin/eject
+#
+# ## and the above mentioned commands
+#
+# for more reference see http://wiki.zmanda.com/index.php/Changers
