Careful planning can help you minimize the impact of data loss. Before you back up, consider the following:
TSAFS supports backup of open files on Novell Storage Services (NSS) volumes if the CopyOnWrite feature is enabled. The Supervisor right is required to back up open files.
To enable CopyOnWrite on a single NSS volume, at the server console, enter nss /FileCopyOnWrite=volume_name
