Note:

These log folders must already exist in order for logging to occur. If these folders do not exist, you must create them.

To create most of these log folders, run the following command on the NetBackup servers and on the Hyper-V server:

Windows:

install_path\NetBackup\logs\mklogdir.bat

UNIX (on master or media servers):

/opt/openv/netbackup/logs/mklogdir

For more detail on snapshot-related logs, logging levels, and the required folders, see the NetBackup Snapshot Client Administrator's Guide.
