Create a Replication Set

You can use the Wizard to create a Replication Set instead of using the procedure below; to do so, right-click the ContinuousDataReplicator icon in the CommCell, and select All Tasks, then select Replication Set Creation Wizard.

Required Capability: Capabilities and Permitted Actions

To create a Replication Set:

1. In the CommCell Browser, right-click the ContinuousDataReplicator icon of the source machine, select All Tasks, then select Add Replication Set.
2. In the General tab, specify a Name for the Replication Set, and a Destination Host that has CDR installed.

   On Windows, in the User Name field, specify a Windows User Account who has the following privileges:

   • Is a member of the local Administrators group on the destination.
   • Has read/write permissions to the product installation folders on the destination.
   • Has read/write permissions to the the replication logs directory on the destination if it is not in the default location.
   • Has read/write permissions to the Job Results directory.

   On Unix, in Data Replication Type area, select Preserve Write Order option for database application. This enables the use of full data journaling necessary to preserve the consistency of the database during replication.

   For Scheduled Replication on Unix, the following options are selected by default to identify the backup data:

   • Use Journaling: This option enables the use of internal journal to identify the backup data. Requires CDR driver; for supported platforms see System Requirements - ContinuousDataReplicator.
   • Create Snapshot: This option enables the use of snapshots to identify the backup data. Requires a snapshot engine; for supported platforms see System Requirements - ContinuousDataReplicator - Snapshot Support.

   For Disk Library Replication, select this option to replicate data between the MediaAgents installed in the source and destination computers.

3. In the Pre/Post Process tab, specify any commands 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. For more information, see Pre/Post Processes.
4. In the Replication Options tab, make any appropriate selections. See the following for more information:
   • Enable or Disable Software Compression for a Replication Set
   • Configure the Replication Set for Data Encryption
   • Configure Recovery Points
   • Configure CDR for Backups of Recovery Points
5. Optionally, make any appropriate selections in the Storage Policy tab. For more information about Recovery Points and backups, see Recovery Points.
6. In the Orphan Files tab, specify how to treat data on the destination, which is not on the source machine. (See Data Replication - Orphan Files.)
7. Optionally, select the minimum file size to perform hash comparisons, and the block size for hashing in the Advanced tab.
8. Optionally, filter the content of any Replication Pairs that are created for this Replication Set in the Filters tab. For more information about CDR 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 the Browse button and expand the file system of the client computer. Click the file/folder/directory that you want to exclude from data replication and then click Add. Repeat this step for each additional entry.
9. To configure User Security for the Replication Set, after it has been created, expand the ContinuousDataReplicator 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.
10. Click OK to save your changes.

To specify that all Replication Pairs created for this Replication Set are to use a Common Base Folder (the same folder on the destination host to contain all destination paths) see Edit a Replication Pair.
