Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, it drives down backup costs while providing unique features for MySQL backups.
New features and improvements:
Percona XtraBackup now prints used arguments to standard output. Bug fixed PXB-1494.
xtrabackup --copy-back didn’t read which encryption plugin to use from plugin-load setting of the my.cnf configuration file. Bug fixed PXB-1544.
xbstream was exiting with zero return code when it failed to create one or more target files instead of returning error code 1. Bug fixed PXB-1542.
Meeting a zero sized keyring file, Percona XtraBackup was removing and immediately recreating it, which could affect external software noticing this file had undergo manipulations. Bug fixed PXB-1540.
[*]xtrabackup_checkpoints files were encrypted during a backup, which caused additional difficulties to take incremental backups. Bug fixed PXB-202.
Other bugs fixed: PXB-1526 “Test kill_long_selects.sh failing with MySQL 5.7.21”.
