======================== Percona |XtraBackup| 1.4 ======================== Released on November 22, 2010 Percona |XtraBackup| version 1.4 fixes problems related to incremental backups. If you do incremental backups, it's strongly recommended that you upgrade to this release. Functionality Added or Changed ------------------------------ * `Incremental backups `_ have changed and now allow the restoration of full backups containing certain rollback transactions that previously caused problems. Please see `Preparing the Backups `_ and the :option:`--apply-log-only`. (From |innobackupex|, the :option:`--redo-only` option should be used.) (Yasufumi Kinoshita) * The |XtraBackup| Test Suite was implemented and is now a standard part of each distribution. (Aleksandr Kuzminsky) * Other New Features * The :option:`--prepare` now reports ``xtrabackup_binlog_pos_innodb`` if the information exists. (Yasufumi Kinoshita) * When :option:`--prepare` is used to restore a partial backup, the data dictionary is now cleaned and contains only tables that exist in the backup. (Yasufumi Kinoshita) * The :option:`--table` was extended to accept several regular expression arguments, separated by commas. (Yasufumi Kinoshita) * Other Changes * Ported to the |Percona Server| 5.1.47 code base. (Yasufumi Kinoshita) * |XtraBackup| now uses the memory allocators of the host operating system, rather than the built-in |InnoDB| allocators (see `Using Operating System Memory Allocators `_). (Yasufumi Kinoshita) Bugs Fixed ---------- * `Bug #595770 `_ - XtraBack binaries are now shipped containing debug symbols by default. (Aleksandr Kuzminsky) * `Bug #589639 `_ - Fixed a problem of hanging when tablespaces were deleted during the recovery process. (Yasufumi Kinoshita) * `Bug #611960 `_ - Fixed a segmentation fault in |xtrabackup|. (Yasufumi Kinoshita) * Miscellaneous important fixes related to incremental backups.
