Has anyone experienced network saturation if there are multiple thousands of people using the PFBackup utility to backup PST files to the network? There are 5,000 plus users at this installation, and we are looking to remove open PSTs from network servers, moving them to the local hard drives. The logoff process initiates the backup / copying for the Outlook Add-In PFBackup to the location specified. The PST files can grow to GB in size. Any information on how this would affect the network with a large user population would be helpful. Thank you.
