Functionality Added or Changed

• For MySQL Server 5.7.21 and later: Servers' use of the keyring_encrypted_file and keyring_aws plugins is now supported. See Working with Encrypted InnoDB Tables for details. (Bug #27127898, WL #10217)

• Information on the executed GTIDs is now included in the mysqlbackup output and the backup log when the backed-up server has GTIDs enabled. (Bug #25978803)

• The buffer size for cloud transfers can now be specified using the new --cloud-buffer-size option. See Cloud Storage Options for details. (WL #11113)

• HTTP Basic Authentication and non-chunked transfer are now supported for backup and restore using OpenStack Swift-compatible object storage services. Two new options, --cloud-basicauth-url and --cloud-chunked-transfer, have been introduced for these purposes. See Cloud Storage Options for details. (WL #11112, WL #11113)

Bugs Fixed

• mysqlbackup failed to restore a TTS (transportable tablespace) backup if the row format of any TTS tables did not match the InnoDB default row format on the target server. This was because the row format of a table was not included in the backup if the table was created with the InnoDB default row format. With this fix, the row format is now always written to the backup, so that tables are always restored with the right row format. (Bug #27445546)

• mysqlbackup failed to backup to an Amazon S3 cloud storage. (Bug #27231229)

• mysqlbackup could not establish a connection to the server with a Unix socket using the option --protocol=SOCKET. (Bug #26977679)

• mysqlbackup did not indicate in its output whether an established connection with the server was encrypted or not. With this fix, the crucial information is now provided. (Bug #26919023)

• An apply-log operation failed when more than one process threads were used for the operation and the backup contained encrypted InnoDB tables. (Bug #26495013)

• On macOS, mysqlbackup failed to determine the relay log file name correctly if the relay log index file name was not specified. (Bug #25574605)

• mysqlbackup only accepts values for --ssl-mode in upper case. With this fix, the option's value has become case insensitive. (Bug #25548088)

• After restoring an incremental backup of a slave server, the file ibbackup_slave_info was missing from the meta folder under the backup directory on the target server. (Bug #25097753)

• When a compressed backup was restored with the --innodb_data_home_dir option pointing to a restore location outside of the data directory, .ibd files were still being copied into the data directory, causing an exception to be thrown at the attempt to start the restored server. (Bug #24826986)
