“Is it possible to lock folders on a Mac so that Retrospect will not update them?”
It is possible to lock folders on a Mac. Just click on a folder, press command-I or choose get info under the file menu to bring up the get info window, select sharing from the show pop-up menu, and check the can’t move, delete, or rename this item option.
Is locking a folder the best way to keep Retrospect from updating that folder? Depending on your exact workflow, probably not. Though Retrospect can skip folders and files that are locked, there are easier ways to do it. Here’s one:
In the selecting window that appears when you click this selecting option you’ll see a pop-up menu. This menu contains the option to exclude any items marked with the cool label. Labels can be set under the file menu for any selected files and folders. By labeling your files accordingly, and initiating this setting in Retrospect, you have an easy way to avoid backing them up and restoring them.
If you press the more choices button in the selecting window you’ll discover that you can exclude items by clicking on the exclude button. You can use all sorts of different criteria to exclude items here: certain names, dates, etc.
