Percona XtraBackup 8.4.0-5 has been released

Percona XtraBackup 8.4.0-5 has been released on Wednesday, December 17, 2025.

Try it out using the Quickstart guide.

Percona has consolidated its build offerings. The Pro builds are no longer required. All features from the Percona XtraBackup 8.4.x Pro build series have been merged into the main open source Community release. The Reduced backup lock time feature, originally introduced in Percona XtraBackup Pro 8.4.0-2 for Pro builds, is now included in the Community release starting with Percona XtraBackup 8.4.0-5.

We recommend downloading Percona XtraBackup for the same platform as your MySQL-compatible server. For example, if your server runs on an ARM64 platform, download the Percona XtraBackup version for ARM64.

This release provides the following bug fixes:

  • Fixed an issue where xbcloud could exit because libcurl attempted to use a libev event loop after it had already been shut down. xbcloud will throw a warning with libcurl 8.11.x versions and may still exit due to CVE-2025-0665. The issue is resolved in libcurl 8.12.0 and later.

  • The --move-back option was not applied when restoring RocksDB files, causing the restore process to always perform a file copy instead of moving the files back to their original location.
