Percona XtraBackup 8.0.7

Percona is glad to announce the release of Percona XtraBackup 8.0.7 on August 7, 2019. Downloads are available from our download site and from 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, it drives down backup costs while providing unique features for MySQL backups.

In release 8.0.7, Percona XtraBackup enables making backups of databases that contain the encrypted system tablespace. Encrypted mysql tablespace is now also supported.

Percona XtraBackup 8.0.7 implements the support of the lz4 compression algorithm so that you could make compressed backups using lz4 (–compress=lz4) in addition to the default quicklz method.

All Percona software is open-source and free.
