Frequently asked questions
Does compression always save the same amount?
No. Compression depends on file type, database format and backup method.
Should I include growth?
Yes. Backups that are safe today can become too small after imports or traffic growth.
Does this replace a backup audit?
No. Verify real backup sizes and restore behavior before relying on a plan.
