Disk vs. File Backup (Retro MS 6.5) in Server, SBS and Multi Server Posted March 21, 2006 · Report reply I quoted from the Mac section? How embarassing. Upon looking again at the KB article "TITLE: Technical Note NO. 503M: Backup to Hard Disks" it doesn't say that it only applies to Macs. I thought that it applied to both. How can you tell that it's only for MACs? Well, at least I posted in the correct forum. I am using the Windows version of Retrospect.
