Between 70% to 80% should be the maximum storage space used. This is for regular queries and day to day operations. You can configure a CloudWatch Alarm to monitor the disk usage of your cluster. If the customer is vacuuming a large table - they currently require approximately 3x the size of it in free space. As an example, a table that consumes 15% of cluster space, will require 45% free space in order to vacuum.

correct, Maintain at least 20% free space or three times the size of the largest table https://d1.awsstatic.com/events/reinvent/2019/Deep_dive_and_best_practices_for_Amazon_Redshift_ANT418.pdf
