I tried this one out from the command line but when it completed I couldn't 
find the log file! I did a sudo updatedb, and when it completed I did a locate 
my_backups but couldn't find it anywhere on my system. Where did it go please?

I don’t have enough bash knowledge for scripting, hence my request.
