    Percona XtraBackup 2.4.9¶

    Percona is glad to announce the release of Percona XtraBackup 2.4.9 on November 29th 2017. Downloads are available from our download site and from apt and yum repositories.

    This release is the current GA (Generally Available) stable release in the 2.4 series.

    New Features¶

    • Percona XtraBackup packages are now available for Ubuntu 17.10 (Artful).

    • xbcrypt now has an ability to decrypt files in parallel by specifying the number of threads with the xtrabackup --encrypt-threads option.

    • xtrabackup --copy-back option can now be used with xtrabackup --parallel option to copy the user data files in parallel (redo logs and system tablespaces are copied in the main thread).

    Bugs fixed¶

    • Percona XtraBackup would fail to backup large databases on 32-bit platforms. Bug fixed PXB-481.

    • Percona XtraBackup failed to build with GCC 7. Bug fixed PXB-502.

    • Percona XtraBackup would hang during the prepare phase if there was not enough room in log buffer to accommodate checkpoint information at the end of the crash recovery process. Bug fixed PXB-506.

    • When backup was streamed in tar format with with the xtrabackup --slave-info option output file xtrabackup_slave_info did not contain the slave information. Bug fixed PXB-507.

    • If xtrabackup –slave-info was used while backing up 5.7 instances, the master binary log coordinates were not properly displayed in the logs. Bug fixed PXB-508.

    • innobackupex --slave-info would report a single m instead of slave info in the standard output. Bug fixed PXB-510.

    • Percona XtraBackup would crash while preparing the 5.5 backup with utf8_general50_ci collation. Bug fixed PXB-748 (Fungo Wang).

    • Percona XtraBackup would crash if xtrabackup --throttle was used while preparing backups. Fixed by making this option available only during the backup process. Bug fixed PXB-789.

    • Percona XtraBackup could get stuck if backups are taken with xtrabackup --safe-slave-backup option, while there were long running queries. Bug fixed PXB-1039.

    Other bugs fixed: PXB-250, PXB-511, and PXB-512.
