Create a Replication Policy

To create a Replication Policy:

From the CommCell Browser, right-click the Replication Policies node, then click New Replication Policy. The Create New Replication Policy dialog is displayed.
In the General tab, specify a name for the Replication Policy and a Destination Host that has the replication Agent installed. If required, for Windows, in the User Name field, specify a Windows User Account that is part of the Local Administrator group on the destination, with read/write permissions for the product installation folders on the destination. If the agent uses replication logs, and the replication logs directory on the destination is not in the default location, then the User Name supplied here must also have read/write permissions for that directory as well.
Specify a Common Base Folder so that all destination paths for all Replication Pairs in the Replication Sets (created with this Replication Policy) will be created in the same location on the destination host.
Specify the type of replication for which the replication sets created using this replication policy will be used. The following replication types are available.
- Continuous Replication - to create replication sets for CDR to replicate data in ContinuousDataReplication mode.
- Remote Backup - to create replication sets for CDR to replicate data in Remote Backup or MediaAgent Replication mode.
- Workstation Backup - to create replication sets for Workstation Backup Agents.
In the Pre/Post Process tab, specify any commands to be run before a data protection operation (like Recovery Point creation, backup job, etc.) and/or after the operation, and specify a User Account with permissions to run the command(s) on the destination machine. For more information, see Pre/Post Processes.
In the Replication Options tab, make any appropriate selections.
- Enable or Disable Software Compression for a Replication Set
- Data Integrity Validation on transfer (See Enable (or Disable) Data Integrity Validation on Network)
- Configure the Replication Set for Data Encryption
- Configure CDR Recovery Points (For ContinuousDataReplicator and Remote Backup types)
- Configure CDR for Backups of Recovery Points (For ContinuousDataReplicator and Remote Backup types)
In the Orphan Files tab, specify how to treat data on the destination, which is not on the source machine.
Optionally, filter the content of any Replication Pairs that are created for this Replication Set in the Filters tab. For more information about Filters, see Replication Filters. To exclude data from data replication operations, do one of the following:
- Click the Add button and, in the Enter Path window, type the complete path (including drive letter) of the file/folder/directory that you want to exclude from data replication. Repeat this step if you want to add more files/folders/directories to the filter.
Click OK to save your changes.

User Security is configured at the Replication Set level. To specify the security options, expand the Agent icon of the source machine, right-click the Replication Set and select Properties, then select the Security tab. For more information, see User Administration and Security.

Add/Update Replication Pairs

Required Capability: Capabilities and Permitted Actions

To add new Replication Pairs, or update existing Replication Pairs:

In the CommCell Browser, right-click a Replication Policy to which you wish to add the Replication Pair, and select All Tasks, then select Manage Pairs.
To add a Replication Pair, in the Manage Pairs dialog, click Add. In the Add Replication Pair dialog box, type a source volume or directory for the Source Path. Keep in mind that this path must be valid source path in the target computer where the replication pair is created, using this replication policy.
To edit a Replication Pair, in the Manage Pairs dialog, select the Pair to edit, click Edit. Make any changes to the source path in the Edit Replication Pair dialog box, and click OK.
To specify that all VSS writers must be engaged when the acquiring the source snap, select the Engage All VSS Writers option. Use this option to create backups that are consistent with the source. The Automatically detect mount points option is not applicable when adding Replication Pairs to the Replication Policy.
When your changes are complete, click Apply.

Filtering of content for Replication Pairs is configured at the Replication Set level; see Replication Filters.

Create a Replication Set from a Replication Policy

Before You Begin

Review Replication Policy.

To create a Replication Set from a Replication Policy:

In the CommCell Browser, right-click the Agent icon of the source machine, select All Tasks, then select Add Replication Set From Policy.
In the Select a Policy dialog box, select the replication policy based on which you wish to create the replication set. The replication policies created for the corresponding agent will be displayed. Click OK.
In the Enter Name dialog box, specify the name of the replication set, and click OK.
The replication set will be created with the configurations available in the selected replication policy.

Delete a Replication Policy

Required Capability: Capabilities and Permitted Actions

To delete a Replication Policy:

From the CommCell Browser, select the Replication Policies node, right-click the desired Replication Policy, click All Tasks and then click Delete.
Click Yes to the confirmation message.
The Replication Policy will be deleted. Note that Replication Sets created from this Replication Policy will have no impact upon deletion.

Apply the Replication Policy Settings to Replication Sets

Required Capability: Capabilities and Permitted Actions

To apply the Replication Policy settings to Workstation Backup agent Replication Sets:

From the CommCell Browser, select the Replication Policies node, and select the desired Replication Policy. If you wish you modify the details of the Replication policy, right-click the Replication policy and select Properties. Modify the details as required.
Right-click the Replication Policy, click All Tasks and then select Apply Settings. The Apply Settings dialog box is displayed with the list of Workstation Backup client computers configured to the CommCell.
Select the Workstation Backup Client computers you wish to apply the Replication Policy settings. Use Select All and Clear All options to select or clear all the clients in the list.
Click OK to apply the settings.
