FromDual Recovery Manager (rman) with progress indicator

Since version 2.1.0 the FromDual Recovery Manager (rman) for MariaDB and MySQL has also a progress indicator for the restore of logical backups made with mysqldump. This feature was implemented because of the numerous requests of FromDual rman users who were not happy with the default mysql behavior.

You can check your current rman version as follows:
