This topic provides an overview of data volumes, and instructions to add data volumes and edit existing data volumes.

About data volumes

A data volume is a folder on a CloudCache where Phoenix stores the backup data. For each data volume, you must set an appropriate size. A data volume permits you to consume a portion of the storage. You can only consume a portion of the storage that is equivalent to the size of the data volume. If your setup requires more storage, you can add data volumes, and set a size for the data volumes. 

After you create CloudCache data volumes, you can resize the data volumes. Ensure that you connect CloudCache to Phoenix Cloud before you add or edit the data volume size. 

Note: You can add up to 10 data volumes for each instance of Phoenix CloudCache. The total size of all the data volumes on all instances of Phoenix CloudCache that you configured must not exceed the size limit specified in your license.

  1. Log on to Phoenix Management Console.
  2. On the menu bar, click All Organizations, and select the required organization from the drop-down list.
