Overview

A Replication Set is similar is concept to a Backup Set which is used by some Agents, and represents a logical grouping of Replication Pairs. This allows you to configure certain properties and activities at the Replication Set level, and thus control all the included Replication Pairs together.

Replication sets can created in the following ways:

• Create a Replication Set manually. See Create a Replication Set for step-by-step instructions.
• Create a Replication Set using the Replication Set Creation Wizard. Create the Replication Set by right-clicking the ContinuousDataReplicator icon in the CommCell Browser and selecting Replication Set Creation Wizard.
• Create a Replication Set from a Replication Policy. A Replication Policy provides a sample template for the Replication Set. See Replication Policy for more details. See Create a Replication set from a Replication Policy for step-by-step instruction.

Configurable Properties and Operations

The following are the properties which can be configured, as well as the operations which can initiated, for a Replication Set.

Common Base Folder

You can optionally specify a Common Base Folder, so that all destination paths for all Replication Pairs in the Replication Set will be created in the same folder on the destination host. This can be useful when you are adding multiple Replication Pairs at the same time, as in the case of replicating application data. 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\

If you change the settings for a Common Base Folder after any Replication Pairs have been created, the changes you make will affect only Replication Pairs created after that point; existing Replication Pairs will not be impacted by the change. A Common Base Folder is specified in the Manage Pairs dialog. For instructions about how to specify a Common Base Folder, see Add or Edit a Replication Pair. For more information about replicating application data, see Application Integration.

Data Replication Type

Select the replication type for the replication policy. One replication policy can have only one replication type. The following three types of replication is possible:

• Continuous Replication - to create replication sets for CDR to replicate data in Continuous Replication mode. See ContinuousDataReplicator for more information.
• Remote Backup - to create replication sets for CDR to replicate data in Remote Backup mode.

Data Compression

Specify compression of replicated data on the network. For more information, see Replication Compression.

Data Encryption

Specify encryption of replicated data on the network. For more information, see Replication Encryption.

Data Replication Monitor

Monitor data replication activities for the Replication Set. For more information, see Monitoring Data Replication.

Destination Host

Select a common Destination Host for all Replication Pairs within the Replication Set. Since each Replication Set can have only one Destination Host, to replicate data to multiple hosts, you must create separate Replication Sets.

Orphan Files

Specify how Orphan Files will be handled, when discovered on the destination computer. For more information, see Orphan Files.

Filters

Specify files, folders, and patterns to be excluded from data replication activities. For more information, see Replication Filters.

Replication Pairs

• Create, delete, and edit Replication Pairs within the Replication Set.

• Specify the single destination computer that all Replication Pairs in the Replication Set will use. Note that different Replication Pairs can be configured for different destination paths within that same destination computer, as long as the source path of each Replication Pair is different.
• Manage the state of one or more Replication Pairs within the Set; start, suspend, resume, or abort data replication activities.

For more information, see Replication Pair.

Recovery Points

• Specify that Recovery Points will be created for the included Replication Pairs.
• Specify the maximum number of Recovery Points to be maintained at any time.
• Specify any Pre/Post Processes to be run before a Recovery Point is created, and/or after one has been created, and specify a User Account with permissions to run the command(s) on the destination machine.
• Specify automatic backups of the Recovery Point with an appropriate Storage Policy and Backup Set.
• Specify whether a mount point will automatically be created for the snapshots that comprise the latest Recovery Point each time one is created.
• Create a Recovery Point on-demand, or based on a schedule.
• Select the snap engine type for Recovery Point creation.
• Browse Recovery Points. See Browse Data - ContinuousDataReplicator.

User Accounts

• You can define an account for accessing the destination directory.
• You can define an account with permissions to execute Pre/Post commands when creating Recovery Points.

See ContinuousDataReplicator in User Accounts and Passwords for more information.

User Security

Configure User Security for the Replication Set, after it has been created. For more information, see User Administration and Security.
