Percona XtraBackup 2.4.8¶
This release is the current GA (Generally Available) stable release in the 2.4 series.
To avoid issues with MySQL 5.7 skipping redo log for DDL Percona XtraBackup has implemented three new options (
xtrabackup --lock-ddl-per-table) that can be used to place MDL locks on tables while they are copied.
xtrabackup --check-privilegesoption has been implemented that can be used to check if Percona XtraBackup has all required privileges to perform the backup.
