Enhanced Performance for Data Duplication

摘要

Systems, methods, computer program products, and apparatuses for enhancing the performance of data duplication are provided. A storage system receives an object, which requires data duplication for increased resiliency. A requisite number of copies of the object are created based on a minimum number defined by a system policy. The storage system stores the object and the requisite number of copies and monitors one or more events in the storage system against predetermined data duplication criteria. The predetermined data duplication criteria are defined within the system policy as criteria for making additional copies of the object over the minimum number. One or more additional copies over the requisite number are created and stored based on the occurrence of the one or more events.

1. In a storage system, a method for data duplication comprising:
receiving an object for storage, which requires data duplication for increased resiliency; creating a requisite number of copies of the object as a minimum number of data duplication sets defined by a system policy; managing storage of the object and the requisite number of copies by monitoring one or more events in the storage system against predetermined data duplication criteria, also defined within the system policy as conditions for performing added data duplication; and based on an occurrence of the one or more events, creating and managing storage of one or more additional copies of the object over the requisite number of copies.
