Percona XtraBackup 8.4.0-3 (2025-05-29)

Get started with Quickstart Guide for Percona XtraBackup.

Release highlights

This release provides improvements and bug fixes.

We recommend that you download the Percona XtraBackup for the same platform as the MySQL-compatible server. For example, if your server is on an ARM64 platform, you should download and use the Percona XtraBackup for ARM64 for that operating system.

Improvements

PXB-3427: Percona XtraBackup now prepares incremental backups faster. The --prepare command directly applies the .delta files. To speed up this process, use the --parallel=X option, replacing X with the number of threads you want to use simultaneously. This option applies the delta files concurrently.

PXB-3199: The xbcloud put operations were updated to include support for ObjectLock-enabled AWS S3 buckets (Thanks to volver for contributing the fix for this issue.)

Bug fixes

• PXB-3426: Fix xtrabackup crashes caused by Key Management Interoperability Protocol (KMIP) component keyring usage.

Pro build bug fixes

PXB-3279: Removed the requirement for the --lock-ddl=reduced option to configure the number of open file handles to match the number of files in the server data directory. This limitation previously made the feature difficult to use on large instances with millions of IBD files.
