Windows primary server upgrades are slowed if a large number of files are in the installation directory
When you upgrade from 9.1 or later releases, the NetBackup Windows primary server upgrade may appear to hang while full control to the NetBackup files is granted. The message in the upgrade reads, Granting full control to NetBackup services over NetBackup files.
As part of the upgrade, the nbfp.exe process updates the installation directory permissions. This process may take longer if the installation directory has a large number of files in addition to logs and the images database. Do not stop the installation while the installer waits for a reply from nbfp.exe.
Customers are advised not to create their own files in the NetBackup installation directory. If there are more than 300,000 files in the install directory, contact Cohesity Technical Support for assistance with the upgrade. More information is available to determine the number of files in the NetBackup installation directory.
