Percona 的 MySQL 备份工具 XtraBackup 发布了 2.0.3 版本，该版本支持新的 -move-back 选项用于替换 -copy-back 在磁盘空间不足的情况下移动文件，该选项将移除备份文件，使用时应该注意。

同时 2.0.3 还修复了一些 bug ：

  • Symlink for innobackupex-1.5.1 binary has been broken in the previous version of XtraBackup. Bug fixed #1038198 (Ignacio Nin).
  • XtraBackup 2.0.2 was not backwards compatible which caused incremental backups created with previous versions to fail on prepare. Bug fixed #1038127 (Sergei Glushchenko).
  • Fix for bug #1022562 introduced a regression that may potentially lead to a 5x increase in disk space occupied by incremental backups. Bug fixed #1043762 (Laurynas Biveinis).
  • A regression was introduced in fix for bug #932623 which caused incorrect handling of compressed tablespaces with the page size of 16K, that were created between the last full or incremental and the next incremental backup. Bugs fixed #1049174 and #1044398 (Laurynas Biveinis).
