When performing backups, reducing the amount of time your server is locked can significantly improve performance and minimize disruptions. Percona XtraBackup 8.4 Pro introduces improvements in how DDL (Data Definition Language) locks (aka Backup Locks) are managed, allowing for reduced locking during backups. In this post, we’ll explore the impact of these enhancements. TL;DR (Summary) […]

This blog is not intended to offer anything extraordinary; instead, consider it an anecdote, a lesson, or simply a proper way of doing things without the need to run a test when in doubt. That said, I must emphasize that, as always, testing everything before deploying to production is essential. Let’s dive into the story: […]

We’re excited to announce that both Percona Server for MySQL and Percona XtraBackup now support the ARM64 architecture on Red Hat Enterprise Linux (RHEL) 8/9 and Oracle Linux (OL) 8/9. The packages with the aarch64.rpm extension can be found on Percona Software Downloads. The aarch64.rpm file extension indicates that the RPM package is specifically built for the ARM64 architecture and intended […]

Percona XtraBackup (PXB) version 8.0.28 supports taking backups for the encrypted tables in your MySQL database using the AWS Key Management Service. For setting up data-at-rest encryption using AWS key management service, please see Configuring Keyring for Encryption Using AWS Key Management Service in Percona Server for MySQL.In this blog post, we will discuss how […]

Ensuring the security and resilience of your data hinges on having a robust backup strategy, and Percona XtraBackup (PXB), our open source backup solution for all versions of MySQL, is designed to make backups a seamless procedure without disrupting the performance of your server in a production environment.When combined with the versatility of Docker containers, […]

With the release of Percona XtraBackup 8.0.34-39, Percona XtraBackup (PXB) allows a backup on server version 8.0.35 and higher. We have removed the server version check because the MySQL 8.0 series has transitioned to bug fixes.A feature change in the MySQL 8.0 series, such as the redo log record structure, could cause PXB to fail […]

This blog was originally published in January 2021 and updated in November of 2023.As businesses and applications increasingly rely on MySQL databases to manage their critical data, ensuring data reliability and availability becomes paramount. In this age of digital information, robust backup and recovery strategies are the pillars on which the stability of applications stands. […]

In the world of data backup and security, physical backups play an extremely important role. Physical backup methods are faster than logical because they involve only file copying without conversion. This type of backup is suitable for large, important databases that need to be recovered quickly when problems occur.

Physical backups are the backups that consist of raw copies of the directories and files that store database contents. In addition to databases, the backup can include any related files, such as log or configuration files. Now, since backup speed and compactness are important for busy, important databases, Percona’s open source physical backup solution – Percona XtraBackup (PXB), takes into account all these aspects and benefits MySQL world with its exceptional capabilities!

This blog post will walk you through how PXB …

To reduce the backup size, save storage space, and speed up the backup and restore process, you can compress a backup with Percona XtraBackup. The XtraBackup --compress option makes XtraBackup compress all output data, including the transaction log file and metadata files, with one of the supported compression …

In this blog post, we will describe the improvements to Percona XtraBackup 8.0.33-28 (PXB), which significantly reduces the time to prepare the backups before the restore operation. This improvement in Percona XtraBackup significantly reduces the time required for a new node to join the Percona XtraDB Cluster (PXC).

Percona XtraDB Cluster uses Percona XtraBackup to do SST (State Snapshot Transfer) from one node to another. When a new node joins the cluster, SST is performed to receive the data from DONOR to the JOINER. JOINER uses PXB to stream the data directory from DONOR. JOINER must prepare the backup before using it. It is observed that when the DONOR has a huge number of tablespaces (one million),  XtraBackup on JOINER …
