How to Backup a MySQL Database on a Linux ServerĪcronis Cyber Backup makes it incredibly easy to create complete backups of your Linux Server systems with a couple of mouse clicks. Using this method reduces downtime significantly versus shutting down the MySQL database and server for the entire time the backup operation needs to run to completion. The scripts utilize the MySQL “ FLUSH TABLES WITH READ LOCK” command to lock tables and records before starting the backup, and then subsequently unlocks the database after Acronis Cyber Backup creates the snapshot. With Acronis backup software, limiting MySQL downtime is relatively simple.Īcronis provides downloadable scripts that are designed to run before and after creating a backup snapshot.
Acronis Pre/Post Operation Scripts to the Rescueīecause shutting down a MySQL server for long periods during a corporate data backup can lead to significant errors and problems in some situations, you will need to find a way to limit the shutdown time as much as possible. Therefore, when backing up MySQL databases used for mission-critical applications, it is essential to limit database downtime as much as possible.
For instance, if the MySQL database powers point of sale or other enterprise software or if it is the backend for a corporate website, shutting down the MySQL server could cause significant downtime and loss of revenue. While shutting down the MySQL database servers and the application that connects to it is the best way to prevent data corruption, there are times when doing so could have serious negative side effects to business operations. Once you are sure that MySQL is no longer active and being used, it should then be safe to go ahead and backup the database without fear of record or table corruption.
This usually requires two separate steps: The best way to avoid corrupted records in a MySQL database backup is to ensure that the database is closed completely and not running during the backup operation.

When reinstalling software, the installation or setup routine usually generates a new database for the program. If you are involved with any of these activities, you probably know that installing or reinstalling applications is the easy part it is the migrating of old data that presents the most challenges. Software upgrades, adding new systems or moving to new servers are but a few of the reasons why fresh installs, reinstallations, and migrations are a common occurrence for most IT departments.
In almost any business environment, software and hardware changes are inevitable. Saving Data for Reinstalls and Migrations So, in this article, that is exactly what we are going to cover: why you need to backup MySQL with Acronis Cyber Backup and how to do it.
