Systems, Methods, and Computer Program Products for Scheduling Processing to Achieve Space Savings

摘要

A method performed in a system that has a plurality of volumes stored to storage hardware, the method including generating, for each of the volumes, a respective space saving potential iteratively over time and scheduling space saving operations among the plurality of volumes by analyzing each of the volumes for space saving potential and assigning priority of resources based at least in part on space saving potential.

1. A method for data deduplication, the method comprising:
identifying a plurality of data objects; for each of the plurality of data objects:
determining a space savings obtained for each of one or more previous deduplication operations on the respective data object;determining an average space savings for the respective object from the determined space savings of the one or more previous deduplication operations; andassigning a deduplication priority to the respective data object based on the average space savings of the respective data object.
