Save storage space using compression, compaction, and deduplication

For volumes on non-AFF clusters, you can run deduplication, data compression, and data compaction together or independently to achieve optimal space savings.

• Deduplication eliminates duplicate data blocks.

• Data compression compresses the data blocks to reduce the amount of physical storage that is required.

• Data compaction stores more data in less space to increase storage efficiency.

Note	These tasks are supported for volumes on non-AFF clusters. Beginning with ONTAP 9.2, all inline storage efficiency features, such as inline deduplication and inline compression, are enabled by default on AFF volumes.

Steps

1. Click Storage > Volumes.

2. Next to the name of the volume for which you want to save storage, click .

3. Click Edit and scroll to Storage Efficiency.

4. Optional: If you want to enable background deduplication, ensure the checkbox is checked.

5. Optional: If you want to enable background compression, specify the storage efficiency policy and ensure the checkbox is checked.

6. Optional: If you want to enable inline compression, ensure the checkbox is checked.
