Deduplication efficiency
First Claim
Patent Images
1. A method for use in improving deduplication efficiency, the method comprising:
- evaluating metadata of a data block for determining write activity of the data block, wherein determining write activity of the data block includes determining whether the data block has been recently modified, wherein the metadata of the data block is accessed using a file system mapping logic; and
based on the write activity, skipping the data block for applying the deduplicating technique.
