Issue Description

This error means that sufficient disk space is not available to do backups.

Please check the free space available in the filesystem used for backups (default is /var/lib/mysql-zrm directory in the machine running ZRM for MySQL).

Add additional disk space to the filesystem and re-run the ZRM for MySQL backup for the backup set.
