　　Percona XtraBackup 1.9.1 發布了，XtraBackup 是一個用來備份 MySQL 的 InnoDB 數據庫的開源工具，支持增量備份。

　　Percona 目前已經在開始 Percona XtraBackup 2.0 的開發，而 1.9.1 版本其實相當于 2.0 的第二個 Beta 版。

　　該版本增加一些令人興奮的新特性和 bug 修復：

　　新特性包括：

　　Backup and restore of LRU dump.

　　For servers that support dump and restore of the XtraDB buffer pool (LRU), namely Percona Server, this will enable a server restored from backup to give excellent performance without a lengthy “warm up” time. If provisioning a slave, this means your new slave will end up with a warmed up buffer pool to mimic that of the master.

　　Streaming incremental backuphotoshop/ target=_blank class=infotextkey>ps.

　　It is now possible to stream incremental backuphotoshop/ target=_blank class=infotextkey>ps, lifting a limitation from previous versions where it was only possible to stream full backuphotoshop/ target=_blank class=infotextkey>ps.

　　Parallel compression

　　Percona XtraBackup can now use multiple CPUs to perform a compressed backup, significantly reducing the amount of time needed.

　　Parallel compression (‘--compress-threads‘) can be used together with parallel file copying (‘--parallel‘). For example, ‘--parallel=4 --compress --compress-threads=2‘ will create 4 IO threads that will read the data and pipe it to 2 compression threads.

　　New streaming format to work with parallel compression.

　　The xbstream format is now supported along with the tar format. The new xbstream format works with parallel compression to (without caching) stream several compressed files at once.

　　tar4ibd functionality is replaced by functionality in the xtrabackup binary itself.

　　The xbstream utility is added

　　This utility has a tar like interface to the xbstream format.
