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 Phoenix CloudCache follows to synchronize backup data to cloud storage.

To ensure optimum bandwidth, we recommend that you set these schedules during 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 CloudCache, set the resources such as data volume and maximum bandwidth. You must map 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, Phoenix CloudCache synchronizes the data with Phoenix Cloud and tries to free the space on CloudCache by removing the non-referenced files. The amount of the space that Phoenix CloudCache frees depends on how frequently the files are changed.

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

Note: Phoenix CloudCache only stores backup data. The metadata is saved to Phoenix 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 on to Phoenix Management Console.
  2. On the menu bar, click All Organizations, and select the required organization from the drop-down list.
  3. Click Manage > CloudCache
  4. Under the Unconfigured CloudCache tab, select a Phoenix CloudCache.
  5. In the Action column, click Configure. The Configure CloudCache page opens.
    Provide the following details:
    Field Description

    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 Phoenix CloudCache denoted with an icon.
    FQDN The fully qualified domain name (FQDN) of the Phoenix CloudCache. 
    Data Volume

    The path to the data folder.

    Note: Your server data is saved to the data folder, and the metadata is saved to 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 Phoenix Cloud if Phoenix agent is unable to back up to CloudCache because either CloudCache server is not reachable or it has run out of disk space.

    If you do not select this check box and CloudCache server is not reachable or runs out of disk space, the backup operation fails.

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

  1. Click Next

Step 2: Attach backup sets

  1. Under the Backup Sets tab, select one or more backup sets that you want to map to the Phoenix CloudCache.
    A backup set represents the data that Phoenix backs up. A backup set can be a bunch of files on a server, a database, or a virtual machine configured for backup. When you attach backup sets to the CloudCache, Phoenix backs up the data it represents and stores it on CloudCache. 
  2. Click Next.

The Phoenix CloudCache to which you attached this server appears under Protect> Windows/Linux 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 Phoenix CloudCache. At the end of the retention period, Phoenix CloudCache is compacted, thus freeing up disk space. The retention period does not determine the schedule for synchronizing data from Phoenix CloudCache to Phoenix 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 Phoenix CloudCache located in New York and London starts at 6 AM EST and 6 AM UTC, respectively.  


  1. Under the Schedule tab, from the Retention Period drop-down list, select the duration for which you want 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 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 Phoenix 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 cloud. Phoenix CloudCache considers this synchronization operation as complete at 1 PM. 
    Max Bandwidth (Mbps) The bandwidth in Mbps that you want Phoenix CloudCache to consume at the time of synchronizing backup data to cloud storage. 
    Repeat on

    The days on which you want Phoenix CloudCache to synchronize backup data to 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 Configured CloudCache on the Manage CloudCache page.
