To modify a storage group via the user interface, complete the following steps

1. In the navigation menu, click Local Storage to expand the menu, then click Storage Groups.
2. Find the desired storage group from the displayed list. Click the (ellipsis icon) in the upper-right corner of the storage group's information pane.
3. Click Edit.
4. For Storage Optimization, select a Compression Type from the drop-down list as needed:
   • Fast— Results in shorter backup time, but with less space savings.
   • Best — Provides the highest space savings, but with a longer backup time.
   • Optionally, configure a Quota by entering an amount and setting the unit (GiB or TiB). If no value is set, the quota will be unlimited. If a quota is currently set, you may increase or decrease the quota value (provided the decreased quota is not less than the current used capacity on the storage group). Once a quota is set, it can be reset to the default value of unlimited.

     NOTE: Quotas define the limit for physical capacity usage. Once reached, data ingests are not allowed until space is recovered through savepoint expiration and cleaner operations.

5. You can modify the following Encryption settings:

   NOTE: For more information about recommended guidelines for setting up encryption, see the topic, Configuring and Using Encryption at Rest.

   NOTE: Due to export regulations, the encryption at rest feature is not available in certain markets, and, therefore, may not be available in your locale.

   • Encryption—Next to Encryption, select or clear as needed.
   • Old Passphrase—Enter the current passphrase you want to change.
   • New Passphrase—Enter the new passphrase to be used to encrypt content encryption keys. (The passphrase string can take up to 255 characters. And, alphanumeric and special characters can be entered as part of the passphrase string.)
   • Confirm Passphrase—Re-enter the encryption passphrase.
   • Encryption Mode—Select the mode of key lifecycle management from one of the following options:
     • Static—A global, fixed key is used to encrypt all data.
     • Internal—Content encryption keys are generated and rotated on a specified period of days.

6. Click Update.
