DYNAMIC PRIORITIZED RECOVERY

摘要

A method, article of manufacture, and apparatus for recovering data. In some embodiments, this includes selecting an object to be recovered, recovering sub-objects of the object based on the priorities assigned to the sub-objects, and reprioritizing the sub-objects based on an application's I/O during recovery. In some embodiments, reprioritizing the sub-objects the sub-objects includes assigning a lower priority to the sub-objects when an application has completed I/O on the object. In some embodiments, recovering sub-objects includes recovering sub-objects to a remote location.

1. A method for recovering data, comprising:
using a processor to select a previously backed up data object to be recovered using backup data, wherein the data object includes a plurality of sub-objects; using the processor to recover the plurality of sub-objects based on a first set of priorities assigned to the sub-objects, wherein at least a subset of the plurality of sub-objects are assigned a priority from the first set of priorities; and using the processor to reprioritize the sub-objects based at least in part on an application's I/O during recovery by assigning a priority from a second set of priorities to at least a subset of the sub-objects, wherein the at least the subset of the plurality of sub-objects is assigned a new priority from a second set of priorities, contemporaneously with recovery of the backed up data object.
