Use this preinstallation checklist to prepare the computer where you will install the ContinuousDataReplicator, and to gather all of the information you will need during the installation.
Verify System Requirements
Verify that the computer where you will install the ContinuousDataReplicator satisfies the minimum requirements. For more information, see System Requirements - ContinuousDataReplicator.
Verify License Requirements
Based on the licensing mechanism used in your CommCell environment, verify that the CommCell has the required licenses to use the ContinuousDataReplicator. For more information, see License Requirements - ContinuousDataReplicator.
Determine the Installation Location
Based on your environment, install the ContinuousDataReplicator on an appropriate computer.
|
Environment |
Where to install the software |
|---|---|
|
Non-Clustered |
On two UNIX computers that you want to back up. The source computer from which you will replicate data and destination computer to which you will replicate the data. |
|
Clustered |
On all physical nodes of the cluster. |
Gather Installation Data
Refer to the items in this section to gather the information that you will need during the installation. Record the information before you begin installing the software, so you can refer to it during the installation.
You can install the ContinuousDataReplicator using either the CommCell Console or the installation package created by the Download Manager. Any item that applies to only one of these installation methods is noted.
Commvault Package to Install
-
For installations using the CommCell Console, install the Continuous Data Replicator package, which is under the Replication category.
-
For installations using the installation package, install the Continuous Data Replicator package.
Note
If the File System Agent is not installed on the computer, the File System Core and File System packages are automatically installed with the package that you selected. The File System Agent will not consume any licenses.
Note: To gather the required information for the File System Agent, refer to "Gather Installation Data" in Preinstallation Checklist for the UNIX, Linux, and Macintosh File System Agent.
Client Computer Details
If the File System Agent or another package is already installed on the computer, you are not required to gather all the computer details again. The level of detail depends on how the package you selected is installed, as follows:
-
For installations using the CommCell Console, the installation program requests only the name of the client computer.
-
For installations using the installation package, the installation program reads the details from the previous installation.
CDR Driver Information
This information is only applicable to installations using the CommCell Console.
By default, the log file is created in the opt/commvault directory. You can change the destination directory. For more information, see Location of Replication Logs.
CDR Source or Destination
This information is only applicable to installations using the installation package.
Determine if the computer will be used by CDR as a source machine, destination machine, or both.
CDR cache directory location and size
This information is only applicable to installations using the installation package.
Determine the location for the CDR cache and cache size.
