Percona XtraBackup 2.4.13 Is Now Available

Percona XtraBackupPercona is glad to announce the release of Percona XtraBackup 2.4.13 on January 18, 2018. You can download it from our download site and apt and yum repositories.

Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, it drives down backup costs while providing unique features for MySQL backups.

New features and improvements:

  • PXB-1548: Percona XtraBackup enables updating the ib_buffer_pool file with the latest pages present in the buffer pool using the --dump-innodb-buffer-pool option. Thanks to Marcelo Altmann for contribution.

Bugs fixed

  • xtrabackup did not delete missing tables from the partial backup which led to error messages logged by the server on startup. Bug fixed PXB-1536.
  • The --history option did not work when autocommit was disabled. Bug fixed PXB-1569.
  • xtrabackup could fail to backup encrypted tablespace when it was recently created or altered. Bug fixed PXB-1648.
  • When the --throttle option was used, the applied value was different from the one specified by the user (off by one error). Bug fixed PXB-1668.
  • It was not allowed for MTS (multi-threaded slaves) without GTID to be backed up with --safe-slave-backup. Bug fixed PXB-1672.
  • Percona Xtrabackup could crash when the ALTER TABLE … TRUNCATE PARTITION command was run during a backup without locking DDL. Bug fixed PXB-1679.
  • xbcrypt could display an assertion failure and generated core if the required parameters are missing. Bug fixed PXB-1683.
  • Using --lock-ddl-per-table caused the server to scan all records of partitioned tables which could lead to the “out of memory error”. Bugs fixed PXB-1691 and PXB-1698.
  • xtrabackup --prepare could hang while performing insert buffer merge. Bug fixed PXB-1704.
  • Incremental backups did not update xtrabackup_binlog_info with --binlog-info=lockless. Bug fixed PXB-1711

Other bugs fixed:  PXB-1570PXB-1609PXB-1632
