PRIORITIZED BACKUP SEGMENTING

摘要

A method, article of manufacture, and apparatus for backing up data. In some embodiments, this includes backing up an object to a repository, segmenting the object into a plurality of sub-objects, and assigning a priority to a sub-object. Segmenting the object may include segmenting the object based on file access patterns. Assigning a priority may include assigning a high priority based on file access patterns, or based on policy, among others.

1. A method for storing data, comprising:
using a processor to back up a plurality of data files to a repository; using the processor to segment the plurality of data files into a corresponding plurality of segments based at least in part on an access pattern associated with each of at least a subset of the plurality of segments, wherein at least a portion of one of the plurality of data files is segmented into one or more segments of a first size based at least in part on an access pattern associated with a first segment; using the processor to assign a priority to each of at least a subset of the plurality of segments; and using the processor to store the assigned priorities in a data structure, wherein a process to recover the segments from the repository recovers the segments based at least in part on the assigned priorities.
