Frequency and migration based re-parsing

摘要

Example apparatus and methods associated with frequency and migration based re-parsing are provided. One example data de-duplication apparatus includes a migration logic and a parsing logic. The migration logic may be configured to perform a data transfer according to an access frequency to the data. The parsing logic may be configured to re-parse the data based on the access frequency to the data. In different examples, parsing the data may be performed in response to migrating the data. In one example, parsing the data may be performed during or after the migration. Additional examples illustrate parsing the data to balance performance against reduction in light of access frequency to the data block.

1. A method, comprising:
accessing frequency data for a data block in a de-duplication system, where the frequency data indicates at least an access frequency to the data block; and selectively performing, as a function of the frequency data, one or more of, migrating the data block from a first storage location to a second storage location, and parsing the data block, where the data block was previously de-duplicated and the parsing is a re-parsing of the data block, or where parsing the data block includes selecting a parsing algorithm and applying the selected parsing algorithm to the data block based, at least in part, on the frequency data.
