Automatic MySQL database backups on Linux. We’ll go over six of the most common ones:ġ. There’s a number of different ways to create a MySQL database backup for different systems. That’s why it may be important to keep database downtime as short as possible. In some cases of large, high transaction databases, downtown can be quantified in lost dollars-per-minute (or even second). In many cases, downtime means revenue losses. Of course, a lot of businesses would be unhappy - or simply unable - to shut down databases if the business itself uses them directly and constantly (enterprise software, corporate website backend, etc). There are two main steps that are required here: closing all of the apps that work with MySQL database and shutting down the MySQL server application itself. First, you’ll likely need to stop the database itself from running at the moment of backup, to prevent data corruption and backup inconsistency. That said, there are a few important steps worth taking before starting up the actual database backup process. Subsequently, this leads to just one more reason why it’s important to have a reliable MySQL backup system in place to begin with.

The same goes for problems that might happen during the process of system migration events.īoth software and hardware changes are inevitable in any business environment, including software upgrades, server hardware changes and the addition of more systems is just a fraction of the reasons why most IT departments are continually dealing with migrations, installs and reinstallations of all kinds. You can save a lot of hard work - and revenue - in case of a data-loss disaster if you’ve got a good MySQL backup set up and working. At the same time, there’s also a number of MySQL backup open source tools available to try for free, as well. Of course, such a large technology adoption sees with it a lot of different premium MySQL backup services. According to various reports, MySQL is used in one way or another in about ¼ of all medium-sized and larger companies. MySQL in its core is a great data repository for a variety of applications (accounting, ERP, web server apps, etc) because of its low-cost open-source licensing rules as well as its efficient and flexible SQL (Structured Query Language) architecture. The importance of MySQL databases and reliable backup systems This is the main reason why correct and regular backup of your databases is important, and this is just as true if your business or server applications are working on MySQL. Most applications can be rendered useless just by removing or breaking their databases.
