Overview

Replication Policies provide a means through which you can configure multiple replication sets within a CommCell from a centralized template. Replication policy consists of a common configuration for a replication set that can be applied to newly created replication set within the CommCell.

During the Replication Policy creation, you configure the template for a replication set by defining the replication type, replication destination, common base folder, and other replication options. Optionally, you can also add replication pairs to the policy. Replication sets (also called Target Replication Sets) created from these replication policies inherit the properties specified in the replication policy. If the replication policy contains any replication pairs, then the replication set is created with the replication pairs by default. Once created, the properties of the replication set can be modified; additional replication pairs can be added and existing pairs can be deleted.

Configurable Properties

This section explains the configurable properties of a Replication Policy.

Once created, the properties of a Replication Policy can be modified at any later time. Any changes to a Replication Policy will affect only the Replication Sets that are newly created after that point.

General

Destination Host

Select a common Destination Host for all Replication Pairs within the Replication Set. All replication sets created from this replication policy will have the same Destination Host.

Common Base Folder

Common Base Folder, which is the destination paths for all Replication Pairs in the Replication Set. This can be useful when you are adding multiple Replication Pairs at the same time.

For example, if you specify \replication\ as the base directory, your Replication Pairs might use the following as their destination directories:

\replication\rep_pair_1\

\replication\rep_pair_2\

\replication\rep_pair_3\

Data Replication Type

Select the replication type for the replication policy.

  • Continuous Replication - to create replication sets for CDR to replicate data in Continuous Replication mode.

Pre and Post Processes

Specify commands for Pre/Post Processes for Data Replication Activities in the Pre/Post Process tab.

Replication Options

Provide additional options for data replication in the Replication Options tab.

Orphan Files

Specify how Orphan Files will be handled, when discovered on the destination computer. For more information, see Orphan Files. The following default settings apply:

  • Continuous Replication - Orphan file handling is turned On by default.
  • Workstation Backup - Orphan file handling is turned Off by default.

Advanced

Specify the advanced hashing options, and set mining tool options (applicable for ContinuousDataReplicator) in the Advanced tab.

Filters

Specify files, folders, and patterns to be excluded from data replication activities.

Replication Policy Operations

The following operations can be performed on a Replication Policy.

Create a Replication Policy

You can create a new Replication Policy from the Create New Replication Policy dialog box. The name of the Replication Policy, Destination Host, Common Base Folder, and the Data Replication Type in the General tab are essential components for a Replication Policy. Follow the options in the rest of the tabs and provide the details as applicable. See Create a Replication Policy for step-by-step instructions.

Add or Update Replication Pairs

You can add replication pairs to the replication policy, defining the source path from which data is replicated. When defining the source path, keep in mind that the path specified in the replication pair must be a valid path in the client computer in which the replication pairs are created using this replication policy.

See Add/Update Replication Pairs to a Replication Policy for step-by-step instructions. You can add multiple replication pairs to a replication policy. Replication sets created with this policy will contain these replication pairs upon creation.

Delete a Replication Policy

When a replication policy is no longer required, you can delete the replication policy. See Delete a Replication Policy for step-by-step instructions.

Apply Settings

Replication Set details for multiple Workstation Backup Agents can be simultaneously updated using the Apply Settings option. You can create a Replication Policy with the desired settings, or modify the details of an existing Replication Policy, and use the Apply Settings option to apply the Replication Policy configuration to the Replication Sets to selected Workstation Backup clients. When applied, the details of Replication Sets of the corresponding Workstation Backup client computers are modified, the Replication Pairs are reset to New Pair state, and the subsequent backup is converted to a Full Backup.

Using the Apply Settings option applies the Replication Policy settings to the Replication Sets, resets all the corresponding Replication Pairs to New Pair state, and converts the following backup job to a Full Backup. It is recommended that you use this option with utmost caution.

See Apply the Replication Policy Settings to Replication Sets for step-by-step instructions.
