Percona XtraBackup 9.7.1-rc1 (2026-07-)

Get started with Quickstart Guide for Percona XtraBackup.

Release Highlights

Percona XtraBackup 9.7.1-rc1 is based on the MySQL 9.7 Long-Term Supported (LTS) release. Percona XtraBackup 9.7.1-rc1 is a Release Candidate. Interfaces and behavior are subject to change before the General Availability (GA) release.

Percona XtraBackup 9.7.1-rc1 supports backing up Percona Server for MySQL 9.7.x and MySQL 9.7.x.

Use the [Percona XtraBackup 8.4 series] to take backups of [Percona Server for MySQL 8.4.x] and MySQL 8.4.x series.

Percona XtraBackup 9.7.1-rc1 release includes new features, improvements and bug fixes.

  • Percona XtraBackup introduces the --check-tables option to validate the structural integrity of InnoDB B-tree indexes during the --prepare phase. Validation during --prepare helps detect corrupted indexes before restore or production deployment.

  • Percona XtraBackup introduces backup size reporting for successful backups. Percona XtraBackup now records backup size in xtrabackup_info and reports the same information in the XtraBackup error log. Backup size reporting helps estimate storage requirements, check that backups work correctly, and plan restores for compressed and streamed backups.

  • 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 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.

New features

  • PXB-3328: Adds the --check-tables option to validate InnoDB B-tree index integrity during the --prepare phase. The option detects structural corruption in backup files before restore or deployment.

  • PXB-3747: Adds backup size reporting for successful backups. Percona XtraBackup now records backup size in xtrabackup_info and reports the same information in the XtraBackup error log.

Improvements

  • PXB-3759: Fixed an issue where xtrabackup terminated unexpectedly when redo log encryption was enabled and innodb_log_buffer_size exceeded 16 MB.

  • PXB-3762: Fixed an issue where xtrabackup --backup --transition-key terminated unexpectedly on servers where undo tablespace encryption keys existed only in redo logs.
