# Commvault Backup and Recovery for Unstructured Data in the Capacity Calculation

Capacity usage is calculated based on the size of the latest backup and/or archive jobs of each active client in the CommCell.

To view capacity calculations for the CommCell environment, see Capacity Types in the License Summary Report.

## Included Data

The capacity calculation includes the application size of the latest full backup or synthetic full backup for each subclient. If the agent has multiple backup sets, the backup set with the largest backup size is counted towards capacity. Even if the jobs are deleted because of the Days Only Retention setting, these full and synth full backups are included in the capacity calculation.

The following agents are covered by the Commvault Backup and Recovery for Unstructured Data capacity license.

## Capacity Usage Increase

Capacity usage can increase because of any of the following actions:

- Deploying newer clients with new data.

- Assigning storage policies to content of newly created subclients.

- Backing up more data using a specific storage policy.

## Capacity Usage Decrease

Capacity usage can decrease because of any of the following actions:

- Deleting a subclient policy. Even if the backup job is retained, it won't be counted towards measurement.

- Disabling backups on the subclient. For more information, see Disabling backups on the subclient.

- Deleting the last full or synthetic full backup.
