Percona XtraBackup 2.2.1 alpha 发布了,改进记录包括:

New Features:

  • Percona XtraBackup has removed the multiple binaries (xtrabackup_56, xtrabackup_55, xtrabackup) and now uses single xtrabackup binary instead for handling backups. Single binary implementation removed the requirement to download server source tarballs and removed different patches which resulted in cleaner code.

  • Percona XtraBackup source layout has been changed to implement the single binary. Percona XtraBackup code can now be found in storage/innobase/xtrabackup.

  • Percona XtraBackup implemented support for Backup Locks.

  • Percona XtraBackup can now store backup history on the server itself in a special table created for that purpose.

  • innobackupex-1.5.1 symlink has been removed, instead innobackupex binary should be used.

  • Percona XtraBackup has removed the script and it’s now built with CMake.

  • Percona XtraBackup has been rebased on MySQL 5.6.16.

Bugs Fixed:

  • Information about tool version used to take the backup was added by implementing backup history feature. Bug fixed #1133017.

  • If an XtraDB-based binary was used to a backup an InnoDB database, it would convert it to XtraDB by adding the XTRADB_1 marker in the dictionary header page and by adding the SYS_STATS table. Bug fixed #988310.
