MySQL備份工具 XtraBackup 2.0.0 GA 發布

XtraBackup 是一個用來備份 MySQL 的 InnoDB 數據庫的開源工具。

XtraBackup 發布了全新里程碑 2.0 的首個 GA 版本，該版本改進可可靠性和用戶體驗，2.0 版本并沒有在最后的 beta 版本 1.9.2 上做任何改動，只是版本號的改變。

• Percona XtraBackup can now save Galera replication information while performing a backup when given the --galera-info option to innobackupex.
• XtraBackup now supports compressed backups. These backups can be done in a parallel way, thus utilizing multiple CPU cores if needed. In previous versions, compression was only possible with streaming backups + external (usually single-threaded) compression utilities, which also had a number of other limitations (e.g. could not be used with parallel file copying, it was required to uncompress the entire backup to restore a single table).
• Percona XtraBackup now supports streaming incremental backups. In previous versions streaming backups were performed by the innobackupex script but incremental backups were done by the xtrabackup binary which calculated deltas by scanning data files. Which meant those two feature were mutually exclusive, i.e. one couldn’t do streaming incremental backups.
• As part of the backup, the LRU dump is now included as well.
• Support for compiling and running Percona XtraBackup against debug versions of InnoDB. This is only for very advanced users.
