Python script for local backups with rsync

In Gnu / Linux there are different programs to carry out the backup but personally I like simple things, far from graphical interfaces (which have nothing wrong, of course, but if I can avoid using it, I avoid).
In the rsync command there is a formidable ally of backups that we often forget to do. It has enough options to make a copy with all the necessary requirements.

The following python script makes backup copies for this purpose. You will see that it is extremely simple and even for those who have absolutely no idea of ​​this language, adding a line for the script to synchronize a new directory is immediate.
In my machine I use an external hard disk that I have called IOmega_HDD, in your case you can rename it in the script according to your case.
Another thing is to add or remove directories from the copy. In the same script as the comment line it is explained how to do it.
To automate the task you can add a line to crontab containing the python interpreter and the path where you want to put the script. I hope it is useful to you.

Warning: the wordpress editor does not allow a spacing at the beginning of the line, thus the necessary indentation in the script has been lost, so I have replaced the blank spaces with periods (.) that you must eliminate with an editor and replace with spaces.
