Configure Phoenix CloudCache

Phoenix Editions: File:/cross.png Business File:/cross.png Enterprise File:/tick.png Elite



After you add, install, and activate Phoenix CloudCache, configure the schedule that the Phoenix CloudCache follows to synchronize backup data to the cloud storage.

To ensure optimum bandwidth, we recommend that you set these schedules during the off-peak hours. To benefit from the wider off-peak windows on weekends, you can set the weekly schedule for a longer duration.

When you configure the CloudCache, set the resources such as the data volume and maximum bandwidth. You must map the backup sets with CloudCache, and define a retention period for each backup set. Phoenix CloudCache backs up data from the servers and maintains the data for the configured retention period. After the retention period for a backup set is over, the Phoenix CloudCache tries to free the space on the CloudCache by removing the non-referenced files. The amount of space that the Phoenix CloudCache frees depends on how frequently the files are changed.

Phoenix CloudCache synchronizes the backup data to the Druva Cloud according to the CloudCache synchronization schedule.

Note: Phoenix CloudCache only stores backup data. The metadata is saved to the Druva Cloud storage. Therefore, you only need to create the Data folder at the time of configuration.

You need to perform the following steps to configure your Phoenix CloudCache:

Step 1: Provide general information

  1. Log in to the Phoenix Management Console.
  2. Click Manage > CloudCache. Note that if the All Organizations menu is enabled, you have to first select an organization and then click Manage > CloudCache.
  3. Under the Unconfigured CloudCache tab, select a Phoenix CloudCache.
  4. In the Action column, click Configure. The Configure CloudCache page opens.
    Provide the following details:





    The name of your Phoenix CloudCache.

    Note: The network status for your Phoenix CloudCache should be connected.

    Network Status

    The current network connection status with the Phoenix CloudCache denoted with an icon.


    The fully qualified domain name (FQDN) of the Phoenix CloudCache. 

    Data Volume

    The path to the data folder. In a Windows CloudCache, you can browse data volumes on the CloudCache server and select a data volume. In a Linux CloudCache the data volume /mnt/data/ is hardcoded. You cannot browse and select another volume.



    • Your server data is saved to the data folder, and the metadata is saved to the cloud storage. 
    • Symbolic links and mounted folders do not appear in the folder structure. 
    • Phoenix CloudCache does not support UNC shares. Ensure that you select a local data folder.


    Volume size

    The size that this volume can accommodate in GB.

    Backup to Cloud if unable to backup to Cache

    The option to enable Phoenix to back up the data directly to the Druva Cloud if the Phoenix agent is unable to back up to the CloudCache because either the CloudCache server is not reachable or it has run out of disk space.

    If you do not select this check box and the CloudCache server is not reachable or runs out of disk space, the backup operation fails. For more information, see True hot restore.

    Note: This functionality is available only for the Phoenix agents with version 3.2 r2743 or later on GovCloud only. For older versions, backups by default fall back to Cloud if the CloudCache server is not reachable or runs out of the disk space.

  1. Click Next

Step 2: Attach backup sets

  1. In the Backup Sets tab, select one, multiple, or all the backup sets, and map to the Phoenix CloudCache.
  2. A backup set represents the data that Phoenix backs up. A backup set can be a bunch of files on your resource configured for backup. When you attach backup sets to the CloudCache, Phoenix backs up the data it represents and stores it on the CloudCache. 
  3. Click Next.

The Phoenix CloudCache to which you attached this server appears under Protect> File Servers > All Servers tab > server_name > File/SQL Backup Sets.

Step 3: Set synchronization schedules

The retention period in each backup set determines the duration for which data from the servers reside on the Phoenix CloudCache. At the end of the retention period, the Phoenix CloudCache is compacted, thus freeing up disk space. The retention period does not determine the schedule for synchronizing data from the Phoenix CloudCache to the Druva Cloud. Synchronization operation occurs as per the CloudCache synchronization schedule. The synchronization schedule follows the Phoenix CloudCache time zone. For example, if you set the synchronization start time to 6 AM, the synchronization operation from the Phoenix CloudCache located in New York and London starts at 6 AM EST and 6 AM UTC, respectively.  



  1. In the Retention & Sync Schedule tab, from the Retention Period drop-down list, select the duration for which you want the Phoenix CloudCache to store your backup data. 

Note: The maximum duration that you can set is 30 days.

  1. Enter or select appropriate values in the following fields.
    Field Description

    Start at

    The time when you want the Phoenix CloudCache to start synchronization. 

    Duration (Hrs)

    The duration in hours within which you want synchronization to occur.

    Note: If the synchronization completes within this duration, Phoenix CloudCache checks for data additions every 10 minutes. If new data is backed up during this period, Phoenix CloudCache synchronizes this new data to the Druva Cloud. For example, if you set Start time to 9 AM and duration to 4 hours, and the synchronization completes before 1 PM, Phoenix CloudCache checks for new data every 10 minutes. Phoenix CloudCache synchronizes this data to the cloud. Phoenix CloudCache considers this synchronization operation as complete at 1 PM. 

    Max Bandwidth (Mbps)

    The bandwidth in Mbps that you want the Phoenix CloudCache to consume at the time of synchronizing backup data to the cloud storage. 

    Repeat on

    The days on which you want the Phoenix CloudCache to synchronize backup data to the cloud storage. 

    Note: We recommend that you create a separate schedule for weekdays and weekends. This is because you can benefit from the wider off-peak windows on weekends, and thus set a longer duration for synchronization operations. 
  2. Click Add More to add multiple schedules.
  3. (Optional) Click the delete icon for a schedule to delete it.
  4. Click Finish.

Phoenix CloudCache appears under the Configured CloudCache tab on the Manage CloudCache page.
