Prepare to Uninstall SnapProtect from Client and MediaAgent Computers

For a successful uninstallation, you must review the following general considerations as well as the considerations for the package that you want to uninstall:

General Considerations

  • Verify that SnapProtect services are running on the CommServe computer.
  • For the client where you plan to uninstall the software, verify that no jobs are in progress or scheduled to occur.
  • If the software was not installed in the default location, you must remove the installation directory after the uninstallation.

Considerations for Specific SnapProtect Packages

If you plan to uninstall any of the following packages, review the considerations listed in the appropriate section:

Server Packages in a Cluster Environment

Server packages are those SnapProtect packages that are installed along with the SQL Server software, such as the Web Server, and Workflow Engine.

If you plan to uninstall a server package from a cluster environment, you must uninstall the package from all the cluster nodes before the next failover occurs.

MediaAgent

When you uninstall the MediaAgent package, the uninstallation program performs the following tasks:

  • Removes all the information about the MediaAgent from the CommServe database.
  • Deconfigures all the libraries and drives that are associated with the MediaAgent.
  • Releases the licenses used by the libraries and stand-alone drives that will be deconfigured.
  • Removes the files and registry entries from the computer hosting the MediaAgent.

Review the following considerations to prepare for the uninstallation:

  • If you plan to move the deduplication database to a new MediaAgent computer, you must copy the database content manually. For more information, see Deduplication Database Move.
  • If you uninstall the MediaAgent from a Solaris computer, make sure to uninstall the SCSI Driver package along with the MediaAgent package.
  • Reassociate the storage policies that use the MediaAgent with a different MediaAgent, or delete the policies if you no longer need them. For more information, see Deleting a Backup or Archive Storage Policy.

ContinuousDataReplicator

The ContinuousDataReplicator must be uninstalled from at least two computers:

  • The server from where you replicated data (source computer).
  • The computer where the replicated data is stored (destination computer).

For more information on the different scenarios for data replication, see Supported Configuration.

Before you uninstall the ContinuousDataReplicator from the source and destination computers, you must delete all replication sets used in your replication scenario. You can delete replication sets if the replication pairs are in the Stopped or New Pair state. For instructions, see Delete a Replication Set.

NAS Clients

NAS components are installed automatically with the MediaAgent software. To uninstall NAS components, you must perform the following tasks on the MediaAgent computer:

  1. Deconfigure the NAS client. For instructions, see Releasing a License (Deconfiguration).
  2. If you no longer need the MediaAgent computer, uninstall the MediaAgent and other SnapProtect packages installed on the computer.

Search Engine

Before you uninstall the Search Engine, you must delete the Search Engine from the CommCell Console:

  1. From the CommCell Browser, expand Storage Resources and click Search Engines.
  2. Right-click the Search_Engine that you want to uninstall and click Delete.
  3. Click Yes to confirm the operation.

    You can proceed to uninstall the Search Engine from the client where it is installed.

File Share Archiver Client

If the File Share Archiver Client and the Driver for File Archiver packages are installed on the same client computer, and if you uninstall one of the packages, then:

  • The driver binaries are removed from the client computer.
  • The driver binaries from the package that is not uninstalled are also removed.
