# Percona XtraBackup 8.0.35-36 (2026-06-04)

Get started with [Quickstart Guide for Percona XtraBackup](..//..//quickstart-overview.md).

## Supported versions

Starting with Percona XtraBackup 8.0.34, you can take backups of Percona Server for MySQL and MySQL version 8.0.34 or later within the 8.0.x series.

Check the latest list of all [Supported versions](..//..//supported-versions.md).

## Release highlights

Percona XtraBackup 8.0.35-36 release includes improvements and bug fixes.

* Percona XtraBackup adds support for Azure Storage accounts with [Hierarchical Namespace (HNS)](https://learn.microsoft.com/en-us/azure/storage/blobs/data-lake-storage-namespace) enabled in `xbcloud delete`. Percona XtraBackup now correctly removes backups from Azure Data Lake Storage Gen2 environments where deletion previously failed due to unsupported HNS behavior.

* Percona XtraBackup improves sparse file handling efficiency by removing redundant `fallocate(PUNCH_HOLE)` calls from `local_write_sparse`.

We recommend that you download the Percona XtraBackup for the same architecture 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-3643](https://perconadev.atlassian.net/browse/PXB-3643): Adds support for Azure Storage accounts with [Hierarchical Namespace (HNS)](https://learn.microsoft.com/en-us/azure/storage/blobs/data-lake-storage-namespace) enabled in `xbcloud delete`. Percona XtraBackup now correctly removes backups from Azure Data Lake Storage Gen2 environments where deletion previously failed due to unsupported HNS behavior.

* [PXB-3658](https://perconadev.atlassian.net/browse/PXB-3658): Improves sparse file handling efficiency by removing redundant `fallocate(PUNCH_HOLE)` calls from `local_write_sparse`.

## Bug fixes

* [PXB-3568](https://perconadev.atlassian.net/browse/PXB-3568): Fixed an issue where `xtrabackup` terminated unexpectedly on RHEL 9 when using `--compress=lz4`.

* [PXB-3759](https://perconadev.atlassian.net/browse/PXB-3759): Fixed an issue where `xtrabackup` terminated unexpectedly when redo log encryption was enabled and `innodb_log_buffer_size` exceeded 16 MB.

## Packaging notes

* Percona XtraBackup 8.0 adds support for Ubuntu 26.04.
