Percona XtraBackup for MySQL Percona is glad to announce the release of Percona XtraBackup 2.2.10 on March 31, 2015. Downloads are available from our download site or Percona Software 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, Percona XtraBackup drives down backup costs while providing unique features for MySQL backups.

Bugs Fixed:

  • Decrypting backup with the wrong key would make the backup unusable and unrecoverable. innobackupex doesn’t automatically delete the *.qp and *.xbcrypt files anymore, after --decrypt and --decompress are used. Bug fixed #1413044.
  • XtraDB Changed Page Tracking wasn’t working with innobackupex. Bug fixed #1436793.
  • Fixed Percona XtraBackup assertion caused by dirty pages remaining in the buffer pool after the log was fully applied. Bug fixed #1368846.
  • Backup will not be prepared and innobackupex will stop with an error if the transaction log file is corrupted and it wasn’t applied to the intended LSN. Previously this was showing only as a warning. Bug fixed #1414221.
  • New status log-applied is introduced for backup prepared with --redo-only to avoid making the backup unusable by preparing full or incremental backup without --redo-only and then applying next incremental on top of it. Incremental backup now can be applied only to backup in log-applied state, but not to full-prepared as it was earlier. Bug fixed #1436790.

Release notes with all the bugfixes for Percona XtraBackup 2.2.10 are available in our online documentation. Bugs can be reported on the launchpad bug tracker. Percona XtraBackup is an open source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases.
