Preinstallation Checklist for ContinuousDataReplicator on UNIX

ContinuousDataReplicator (CDR) replicates data from a source computer to a destination computer. For more information, see Overview - ContinuousDataReplicator.

Use this preinstallation checklist to prepare the computer where the ContinuousDataReplicator will be installed and to gather all of the information you will need during the installation.

  • 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.

    SnapProtect package to install
    • For installations using the CommCell Console, install the Continuous Data Replicator package, which is listed under the Replication category.
    • For installations using the installation package, install the Continuous Data Replicator package.

    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 you selected. The File System Agent will not consume any license.

    To gather the required information for the File System Agent, refer to the Gather Installation Data section in the 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:
    • 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/snapprotect 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, or 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.
