Simple Script to Backup Smaller MYSQL Databases remotely
Here is a simple script you can use to add as a job that you can use to backup smaller remote MYSQL DB’s. This script will take a mysql dump, date it, then add it to an archive (with the date), then the uncompressed file is deleted. It is perfect to use as a daily cronjob. The instructions are specifically for Ubuntu, but it can be easily modified for Unix or even a Windows batch file.
