Abstract
Techniques and mechanisms are provided to allow for selective optimization, including deduplication and/or compression, of portions of files and data blocks. Data access is monitored to generate a heat index for identifying sections of files and volumes that are frequently and infrequently accessed. These frequently used portions may be left non-optimized to reduce or eliminate optimization I/O overhead. Infrequently accessed portions can be more aggressively optimized.
Claims20
A method, comprising:
- determining whether a first portion of a file is less frequently accessed than a second portion of the file;
- based on a determination that the first portion of the file is less frequently accessed than the second portion of the file, performing optimization using a higher reduction ratio on the first portion of the file than on the second portion of the file.
An apparatus, comprising:
- a processor configured determine whether a first portion of a file is less frequently accessed than a second portion of the file;
- wherein the processor is further configured to optimize the file;
- wherein optimization is performed using a higher reduction ratio on the first portion of the file than on the second portion of the file based on a determination that the first portion of the file is less frequently accessed than the second portion of the file.
A non-transitory computer readable medium, comprising:
- computer code for determining whether a first portion of a file is less frequently accessed than a second portion of the file;
- and
- computer code for optimizing the file;
- wherein optimization is performed using a higher reduction ratio on the first portion of the file than on the second portion of the file based on a determination that the first portion of the file is less frequently accessed than the second portion of the file.
