Percona XtraBackup 8.0.8

Percona is glad to announce the release of Percona XtraBackup 8.0.8 on November 21, 2019. Downloads are available from our download site and from 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.

All Percona software is open-source and free.

New Features and Improvements

  • Support log archiving feature in PXB 8.0. More information in PXB-1912 and in the Redo Log section of MySQL documentation
  • For the MyRocks storage engine, support the creation of renewable checkpoints (controlled via --rocksdb-checkpoint-max-age and --rocksdb-checkpoint-max-count) to minimize the amount of binary logs to apply after the backup was completed. Using renewable checkpoints, Percona XtraBackup only copies the SST files that were created after the previous checkpoint. More information in PXB-1915.
  • Two options (–-backup-lock-timeout and -–backup-lock-retry-count) were added to enable the configuring of the timeout for acquiring metadata locks in FLUSH TABLES WITH READ LOCK, LOCK TABLE FOR BACKUP, and LOCK BINLOG FOR BACKUP statements. More information in PXB-1914

Bugs Fixed

  • An encrypted table could not be restored when ADD INDEX or DROP INDEX commands had been run on the table. Bug fixed PXB-1905
  • In some cases xtrabackup --prepare could fail to decrypt a table but reported that the operation completed ok. Bug fixed PXB-1936
  • xtrabackup --move-back did not complete successfully when the encrypted binlog file. Bug fixed PXB-1937.
  • Percona XtraBackup could crash during the prepare stage when making an incremental backup when a multi valued index was being added or dropped for JSON data. Bug fixed PXB-1913.
