Earlier this year I wrote an article about creating scripts for backing up your MySQL databases.
I have also been learning Python on and off and learning quite a bit about variables and loops. While the syntax doesn’t carry over to BASH, the the logic does.
Combining the ability of password-less root login and for-do loops, I was able to drastically clean up the size of my original database backup script (my first reference above). To be exact, I had nine databases and 35 lines of code. My new script has 10 lines of code. Furthermore, my original script wasn’t “intelligent” in the sense that you would have to update it (and make it longer) anytime you wanted to backup an additional database. The script I am going to discuss in this article should stay at ~10 lines regardless of how many databases are being backed up on the server.
So today’s script is vastly shorter and, better yet, will automatically backup any new database you add to your MySQL instance! Awesome right? (more…)
