MySQL Enterprise Backup 8.0.27 is the latest release for MySQL Enterprise Backup. It only supports MySQL Server 8.0.27. For earlier versions of MySQL 8.0, use the MySQL Enterprise Backup version with the same version number as the server. For MySQL server 5.7, please use MySQL Enterprise Backup 4.1.
During an incremental backup operation, mysqlbackup quit unexpectedly after receiving a segmentation error when the disk was full. This fix adds proper handling for a disk full error. (Bug #33123802)
extractoperation for a compressed backup sometimes failed if an undo log truncation had taken place during the time the backup was created. (Bug #33082132)
A backup operation failed when backing up tables that used the
keyring_hashicorpplugin for InnoDB table encryption. It was because the HashiCorp Vault AppRole authentication secret ID supplied using the
--encrypt-passwordoption was obfuscated when sent to the server, and the issue has been fixed by this patch. (Bug #33020080)
References: This issue is a regression of: Bug #32284801.
A restore operation failed when, during the creation of the backup, some operation (for example, renaming) was performed on an external general tablespace. It was because mysqlbackup was copying the tablespace twice to the same location on the target server, and that has been corrected by this fix. (Bug #32934170)
