Storage utilization determinations in cloud-based storage systems

An apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

• determining a fractional capacity utilization based on references to deduplicated data associated with a user-visible entity in a cloud-based storage system, wherein the fractional capacity utilization associated with the user-visible entity comprises an amount of data stored within the cloud-based storage system that is exclusively associated with the user-visible entity, determined by:
• identifying all blocks of data stored within the cloud-based storage system that are unique to the user-visible entity or unique to a snapshot of the user-visible entity;
• and
• based on the determination, determining a total capacity utilization for the user-visible entity.
