 Action is based on using a here doc to execute commands on the router.
-The backup is created using the "//nvram save//" command. This is how backups are done in the web interface.
+ \\ \\ The backup is created using the "//nvram save//" command. This is how backups are done "under the hood" in the web interface.
-You may cross-check that the backups are identical to the ones via web  interface by a) download backup via GUI b) create backup by script, c) copy both files to router d) convert both files by "nvram convert <filename1/2>  > result_file1/2.txt e) diff the two resulting text files. (I believe this cross check hints are obsolete....?!?!?)
+You may cross-check that the backups are identical to the ones via the GUI using the following steps:
-The script then archives the resulting data in a tar file and sends it through the netcat command, which transfers it over the network.

-A configurable number of backups is kept, older ones are deleted.
+  - Download the backup via the graphical interface
+  - Create a backup via a script
