Replicating Snapshots

You can copy Amazon snapshots between geographic regions, or share snapshots from one Amazon account to another.


  • Snapshot replication is supported only for volumes that use default encryption.
  • Snapshot replica sharing is not supported for volumes that use default or custom encryption.

Cross-Account Replication

You can replicate snapshots of Amazon instances to a different Amazon account.

You can restore only from the primary snapshot on the source account.


  • You can only replicate snapshots that are encrypted with the default encryption set by Amazon Web Services (AWS). Replication of custom encrypted snapshots is not supported.
  • You can map only one destination region to each configured source region per subclient.

Before You Begin

  • Use a disk library for the snapshot copy target. For more information about disk libraries, see Disk Libraries.


  1. Select the Storage tab from the CommCell Console menu bar.
  2. Click the Array Management tool.

    The Array Management window appears.

  3. Select the Amazon client for which you want to set the Array controller that will be used as the MediaAgent for the selected client, and then click Edit.

    The Array Properties dialog box appears.

  4. Select the Array Controllers tab. Select the array accordingly, and then click OK.
  5. Click OK to close the Array Management window.
  6. Create a second snapshot copy for the Amazon storage policy, in addition to the primary snapshot copy for the storage policy.
    1. From the CommCell Browser, expand Policies > Storage Policies.
    2. Right-click the storage policy that is used for the Amazon backup, and then select All Tasks > Create New Snapshot Copy.

      The Snap Copy Properties dialog box appears.

    3. On the General tab, provide the copy information:
      • In the Copy Name box, type a unique name.
      • Under Default Index Destination, select the library and a MediaAgentfor the snapshot copy.

        Note: When you select a disk library, the Drive Pool list and the Scratch Pool list are dimmed because they are applicable only for tape libraries.

    4. Under Array Replication, select the Vault/Replica option.
    5. On the Retention tab, specify the rules that determine how long the software keeps the data.

      For information on the retention rules, see Copy Properties - Retention.

    6. On the Copy Policy tab, select the Specify Source for Array Replica Copy check box, and then from the list, select the snapshot copy storage policy.
    7. Click OK.
  7. Select the source and destination regions for the snapshot copies.
    1. From the CommCell Browser, navigate to Client Computers > virtualization_client > Virtual Server > Amazon > backup_set.
    2. Right-click the subclient, and select Properties.

      The Subclient Properties dialog box appears.

    3. On the IntelliSnap Operations tab, configure snap replication options:
      • Select Enable Snap Replication.
      • Under Region Map, select Source Region and Destination Region.

        The source region is where the snapshots will be picked up for copying and the destination region is the endpoint to which the snapshots will be copied. This can be configured as per user requirement.

      • Click Add Region to save the region mapping in the database.
      • To replicate to a different account, select Enable cross account copy and select the virtualization client for the account from the Destination Client list.

        The replicated snapshot is shared from the source account to the destination account. You can only restore from a replicated snapshot on the source account.

      • Click OK.

        Note: After running a snapshot backup, while running an auxiliary copy job, select the snapshot replica copy to use, and then select Use Scalable Resource Allocation.
