If NetBackup 10.3 upgrade fails on Windows, revert to previous log folder structure
The legacy log folder structure for non-root or non-admin invoked process logs has changed. The new folder structure is created under the process log directory name. For more information, refer to the File name format for legacy logging section from the NetBackup Logging Reference Guide.
For Windows, if the upgrade to NetBackup 10.3 fails and rollback occurs, run the following command to continue working on an earlier NetBackup version:
mklogdir.bat -fixFolderPerm
For more information, refer to the mklogdir command from the NetBackup Commands Reference Guide.
