TOTAL QUOTAS FOR DATA STORAGE SYSTEM

摘要

Quotas are tracked for user usage of hard disk drive space and offline backup storage space. The quota is enforced against the total space utilized by a user, not just high tier hard drive space usage. When data is migrated from hard disk drive space to backup storage space, data metadata is updated to reflect data kept offline for the user. As such, when users request to store new data, the data usage of hard disk space and backup storage space is determined from the metadata that reflects both data types, and the total storage spaced for the user is used to grant or reject the user's request to store more data in the system.
