You can define multiple labeled directories in a semicolon-separated list. For example: innodb_redo_log_archive_dirs=’label1:/backups1;label2:/backups2’ A label can be any string of characters, with the exception of colons (:), which are not permitted. An empty label is also permitted, but the colon (:) is still required in this case. A path must be specified, and the directory must exist. The path can contain colons (’:’), but semicolons (;) are not permitted.
