Changes in MySQL Enterprise Backup 8.0.13 (2018-10-22)


     * Functionality Added or Changed

     * Bugs Fixed

Functionality Added or Changed


     * mysqlbackup now supports backup compression (the use of
       the --compress and --uncompress options) for incremental
       backups (except for incremental backups created with the
       --incremental-with-redo-log-only option).

     * mysqlbackup now supports transparent page compression for
       InnoDB tables. The support is enabled by setting the
       mysqlbackup option --compress-method=punch-hole; see
       description for the option for details.

Bugs Fixed


     * mysqlbackup hung when a backup operation failed due to a
       full disk. With this fix, mysqlbackup quits gracefully in
       the situation by throwing an error. (Bug #28399821)

     * A mysqlbackup operation on an image stored on an
       OpenStack cloud storage service sometimes failed with a
       segmentation fault or a bad URL error. It was because of
       a race condition caused by an uninitiated variable, which
       has been eliminated by this fix. (Bug #28189239, Bug
       #28183729)

     * Backups for databases with encrypted InnoDB tables failed
       when the --compress option was used. (Bug #28177466)

     * A mysqlbackup operation on an image stored on an
       OpenStack cloud storage service failed with a 401
       Unauthorized error when the operation took a long time
       and the authentication token for the cloud access
       expired. With this fix, a separate thread in mysqlbackup
       requests a new token from the OpenStack cloud service in
       that situation, so that the operation can continue. (Bug
       #27893174)

     * When an incremental backup was restored without using the
       --log-bin option, the binary log was not restored to its
       original location on the backed up server, but to the
       location specified by --log-bin earlier during the
       restore of the base backup. The same occurred for relay
       logs of incremental backups for slaves when the
       --relay-log option was not used. (Bug #27545745)
