    Percona XtraBackup 2.4.8¶

    Percona is glad to announce the release of Percona XtraBackup 2.4.8 on July 24th 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¶

    • To avoid issues with MySQL 5.7 skipping redo log for DDL Percona XtraBackup has implemented three new options (xtrabackup --lock-ddl, xtrabackup --lock-ddl-timeout, xtrabackup --lock-ddl-per-table) that can be used to place MDL locks on tables while they are copied.

    • New xtrabackup --check-privileges option has been implemented that can be used to check if Percona XtraBackup has all required privileges to perform the backup.

    Bugs fixed¶

    • xtrabackup would hang with Waiting for master thread to be suspended message when backup was being prepared. Bug fixed PXB-499.

    • xtrabackup would fail to prepare the backup with 6th page is not initialized message in case server didn’t properly initialize the page. Bug fixed PXB-500.

    • xbstream could run out of file descriptors while extracting the backup which contains many tables. Bug fixed PXB-503

    • When a table was created with the DATA DIRECTORY option xtrabackup would back up the .frm and .isl files, but not the .ibd file. Due to the missing .ibd files backup then could not be restored. Bug fixed PXB-504.

    • Percona XtraBackup incorrectly determined use of master_auto_postion on a slave, and thus generated invalid xtrabackup_slave_info file. Bug fixed PXB-505.

    • Percona XtraBackup will now print a warning if it encounters unsupported storage engine. Bug fixed PXB-713.

    • Percona XtraBackup would crash while backing up MariaDB 10.2.x with --ftwrl-\* options. Bug fixed PXB-790.

    • xtrabackup --slave-info didn’t write the correct information into xtrabackup_slave_info file when multi-source replication was used. Bug fixed PXB-1022.

    • Along with xtrabackup_checkpints file, xtrabackup now copies xtrabackup_info file into directory specified by xtrabackup --extra-lsndir option. Bug fixed PXB-1026.

    • GTID position was not recorded when xtrabackup –binlog-info option was set to AUTO. Bug fixed PXB-1030.
