The backup user was missing the necessary CREATE
privilege for the mariadb_backup_history table
within the mysql schema, causing backups to fail
when attempting to create this table.
This patch addresses the issue by granting the backup
user the required CREATE permission specifically for
the mariadb_backup_history table. With this change,
the backup process can now complete successfully
without manual intervention for user permissions.
