Offered free as an open source solution, XtraBackup drives down backup costs while providing unique features for MySQL backup.

SHOW MASTER STATUSto obtain binlog file and position. This could trigger a bug if the server being backed up was standalone server (neither master nor slave in replication) and binlog information wasn’t available. Fixed by not creating

xbtemptemp files behind due to a typo. Bug fixed #1172016.
xtrabackup_pidfile left inside tmpdir could cause SST to fail. Fixed by fix checking if
