Percona XtraBackup 2.4.6Percona announces the GA release of Percona XtraBackup 2.4.6 on February 22, 2017. You can download it from our download site and apt and yum repositories.

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, Percona XtraBackup drives down backup costs while providing unique features for MySQL backups.

New features:
  • Percona XtraBackup implemented a new --remove-original option that can be used to remove the encrypted and compressed files once they’ve been decrypted/decompressed.
Bugs Fixed:
  • XtraBackup was using username set for the server in a configuration file even if a different user was defined in the user’s configuration file. Bug fixed #1551706.
  • Incremental backups did not include xtrabackup_binlog_info and xtrabackup_galera_info files. Bug fixed #1643803.
  • In case a warning was written to stout instead of stderr during the streaming backup, it could cause assertion in the xbstream. Bug fixed #1647340.
  • xtrabackup --move-back option did not always restore out-of-datadir tablespaces to their original directories. Bug fixed #1648322.
  • innobackupex and xtrabackup scripts were showing the password in the ps output when it was passed as a command line argument. Bug fixed #907280.
  • Incremental backup would fail with a path like ~/backup/inc_1 because xtrabackup didn’t properly expand tilde. Bug fixed #1642826.
  • Fixed missing dependency check for Perl Digest::MD5 in rpm packages. This will now require perl-MD5 package to be installed from EPEL repositories on CentOS 5 and CentOS 6 (along with libev). Bug fixed #1644018.
  • Percona XtraBackup now supports -H, -h, -u and -p shortcuts for --hostname, --datadir, --user and --password respectively. Bugs fixed #1655438 and #1652044.

[UPDATE 2016-02-28]: New packages have been pushed to repositories with incremented package version to address the bug #1667610.
