Restoring from a mediaset spanning multiple harddrives in Retrospect 9 or higher for Macintosh Posted January 9, 2018 · Report reply I don't archive, and I Recycle each of my rotating Media Sets every three weeks, so I've never been faced with this problem. However I think barup should look at this YouTube video, especially from minute:second 0:20 to 2:25. Unfortunately Retrospect Inc. only made a version of that video for Retrospect Windows, so barup will have to get used to Media Sets being referred to as Backup Sets and other UI differences. The equivalent operation is documented on pages 128-130 of the Retrospect Mac 14 User's Guide. My basic idea is that, by searching for at least some the file/folder names he/she wants to Restore, barup will be able to see the dates on which those files were written to the Backup Set used for archiving. That should give him/her an idea which drives are needed. If the drives haven't been externally labeled with the dates they span, he/she can look at the creation and last-updated dates of the the Media Set members (the files that start with a number followed by a dash within the folder for the Media Set within the Retrospect folder) on them using Get Info.
