Granular application data lifecycle sourcing from a single backup

摘要

A system or method for granular application data lifecycle sourcing from a single backup is disclosed. In one embodiment of the method, a computer system periodically creates a primary backup copy of data stored on a storage system in order to create a plurality of primary backup copies. The computer system also periodically creates a secondary backup copy of data stored on the storage system in order to create a first plurality of secondary backup copies, wherein each of the secondary backup copies of the first plurality is created in part by copying data from a respective one of the primary backup copies. The periodicity of creating the primary backup copies, however, is distinct from the periodicity of creating the secondary backup copies of the first plurality.

主权项

1. A method comprising:
periodically creating a primary backup copy of data stored on a storage system in order to create a plurality of concurrently existing, primary backup copies; and periodically creating a first backup copy of data stored on the storage system in order to create a plurality of first backup copies, wherein
each of the first backup copies is created in part by selectively copying some, but not all of the data from a respective one of the primary backup copies, wherein
the selectively copying the some, but not all of the data is based, at least in part, on a predetermined retention period associated with the some, but not all of the data, wherein
the predetermined retention period of the some, but not all of the data is distinct from a different retention period associated with other data in the primary backup copy; wherein a first periodicity of creating the primary backup copies is once and only once each day; and wherein a second periodicity of creating the first backup copies is once and only once each week.
