Things to Note

  • innobackupex was previously deprecated and has been removed
  • Due to the new MySQL redo log and data dictionary formats the Percona XtraBackup 8.0.x versions will only be compatible with MySQL 8.0.x and the upcoming Percona Server for MySQL 8.0.x
  • For experimental migrations from earlier database server versions, you will need to backup and restore and using XtraBackup 2.4 and then use mysql_upgrade from MySQL 8.0.x

Improvements

  • PXB-1655: The --lock-ddl option is supported when backing up MySQL 8

Bugs Fixed

  • PXB-1678: Incremental backup prepare with the --apply-log-only option could roll back uncommitted transactions
  • PXB-1672: The MTS slave without GTID could be backed up when the --safe-slave-backup option was applied.
