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 would hang with
Waiting for master thread to be suspendedmessage when backup was being prepared. Bug fixed PXB-499.
xtrabackup would fail to prepare the backup with
6th page is not initializedmessage in case server didn’t properly initialize the page. Bug fixed PXB-500.
When a table was created with the
DATA DIRECTORYoption xtrabackup would back up the
.islfiles, but not the
.ibdfile. Due to the missing
.ibdfiles backup then could not be restored. Bug fixed PXB-504.
Percona XtraBackup incorrectly determined use of
master_auto_postionon a slave, and thus generated invalid
xtrabackup_slave_infofile. Bug fixed PXB-505.
Percona XtraBackup will now print a warning if it encounters unsupported storage engine. Bug fixed PXB-713.
Percona XtraBackup would crash while backing up MariaDB 10.2.x with
--ftwrl-*options. Bug fixed PXB-790.
