About NetBackup server software removal on Windows systems
When you remove NetBackup server software, the process deletes the Cohesity NetBackup directories from the server.
You can remove NetBackup server software in the following ways:
Remove server software, configuration, and catalog information.
Remove server software and save NetBackup configuration and catalog information.
If you intend to reinstall NetBackup, use this procedure to save the configuration, catalog, and log file information before you remove NetBackup.
If the postgresql.msi does not uninstall PostgreSQL, you must set a registry key to allow a manual uninstall. The key name is HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\NetBackup Scale Out Relational Database Service. The value name is BlockUninstall. It is set to 1 by default. Set the value to 0, save, and retry the uninstall.
Note:
As part of the removal of the NetBackup server software, the security certificates are automatically deleted. If you want to retain the certificates, please save them before removing NetBackup.
More information about this topic is available. Please refer to the information on retaining host ID-based certificates when reinstalling NetBackup in the NetBackup Security and Encryption Guide.
Note:
After an uninstall, some registry and some directory information remain on a Windows computer. This behavior is by design, as these files may be in use by either the NetBackup Authentication Service or the NetBackup Authorization Service.
For clusters, perform all steps on all nodes of the cluster.
