Question Backup and free disk space

[dvl]

Hi everyone!
Can someone tell me. If the largest SQL database of one of my customers is 20GB, what is the minimum amount of free disk space on C:\ partition, where Plesk is installed. I am asking for versions of Plesk before 17.5 and after 17.5 Thank you!
