Announcement: Second Alpha Build of Percona XtraBackup 8.0 Is Available

The second alpha build of Percona XtraBackup 8.0.2 is now available in the Percona experimental software repositories.

Note that, due to the new MySQL redo log and data dictionary formats, the Percona XtraBackup 8.0.x versions will only be compatible with MySQL 8.0.x and Percona Server for MySQL 8.0.x. This release supports backing up Percona Server 8.0 Alpha.

For experimental migrations from earlier database server versions, you will need to backup and restore and using XtraBackup 2.4 and then use mysql_upgrade from MySQL 8.0.x

PXB 8.0.2 alpha is available for the following platforms:

• RHEL/Centos 6.x
• RHEL/Centos 7.x
• Ubuntu 14.04 Trusty*
