Managing Data Reduction
Data Reduction uses compression and deduplication to decrease the amount of disk space used by volume data.
Compression reduces the amount of space used by a volume by encoding data. Deduplication finds duplicate pages and removes them,
conserving the disk space that would be used by additional copies. When deduplication is used, compression is also applied to a volume.
Data Eligible for Data Reduction
To reduce the impact of data reduction on read and write operations, a limited amount of data is eligible for compression and
deduplication. Data Reduction Input limits the type of data that is eligible for data reduction. The following options are available for Data
Reduction Input:
• Inaccessible Snapshot Pages – Allows Data Reduction to process data frozen by a snapshot and made inaccessible by new data
written over the original data in the snapshot.
• All Snapshot Pages – Allows Data Reduction to process data frozen by a snapshot.
Change the Data Reduction Input
Change the type of data that compression and deduplication reduces.
