Percona XtraBackup 2.4.8¶
Percona is glad to announce the release of Percona XtraBackup 2.4.8 on July 24th 2017. Downloads are available from our download site and from apt and yum repositories.
This release is the current GA (Generally Available) stable release in the 2.4 series.
New Features¶
-
To avoid issues with MySQL 5.7 skipping redo log for DDL Percona XtraBackup has implemented three new options (
xtrabackup --lock-ddl
,xtrabackup --lock-ddl-timeout
,xtrabackup --lock-ddl-per-table
) that can be used to place MDL locks on tables while they are copied. -
New
xtrabackup --check-privileges
option has been implemented that can be used to check if Percona XtraBackup has all required privileges to perform the backup.
Bugs fixed¶
-
xtrabackup would hang with
Waiting for master thread to be suspended
message when backup was being prepared. Bug fixed PXB-499. -
xtrabackup would fail to prepare the backup with
6th page is not initialized
message in case server didn’t properly initialize the page. Bug fixed PXB-500. -
xbstream could run out of file descriptors while extracting the backup which contains many tables. Bug fixed PXB-503

file. Due to the missing.ibd
files backup then could not be restored. Bug fixed PXB-504. -
Percona XtraBackup incorrectly determined use of
master_auto_postion
on a slave, and thus generated invalid xtrabackup_slave_info file. Bug fixed PXB-505. -
