Percona is glad to announce the release of Percona XtraBackup 2.0.1 on June 25th, 2012. Downloads are available from our download site and Percona Software Repositories.

This release is the current GA (Generally Available) stable release in the 2.0 series.

This release contains over 20 fixed bugs, some of the more significant bugs fixed are:

  • After creating a full compressed backup, performing a compressed/uncompressed incremental backup would fail because xtrabackup_checkpoints was compressed. This has been fixed by omitting xtrabackup_checkpoints from compression, so that a full backup could be used for incremental backups without decompression. Bug fixed #977652 (Alexey Kopytov).
  • Streaming backups with –stream=tar would fail if the file size was bigger than 8GB. Fixed by changing the libarchive format from USTAR to restricted PAX which supports bigger file sizes. Bug fixed #977998 (Alexey Kopytov).
  • innobackupex was calling the tar utility unconditionally when streaming ib_lru_dump and xtrabackup_galera_info. Which led to a broken stream when the xbstream format was used. Bug fixed #983720 (Sergei Glushchenko).
  • XtraBackup binary could fail with the “log block checksum mismatch” error when reading the partially written log block. Bug fixed #1015416 (Alexey Kopytov).

Release notes with all the bugfixes for Percona XtraBackup 2.0.1 are available in our online documentation. Bugs can be reported on the launchpad bug tracker.
