Yes, that's how it's supposed to work. Specific to my situation, I have a domain computer with sync partnership set up (desktop and documents are synced to a server). Offline files are enabled so there is a local cache on the PC for those synced folders (located in the CSC folder). As expected, I can access all files on the desktop and documents when the PC is removed from the network. However, after running the repair, all cached data is deleted and thus requires a full sync when the PC is reconnected to the network. Normally, this isn't a problem, just requires a bit of time. However, if there's a sync error and the user has a file that hasn't been synced to the server before we run the repair and that file gets deleted, then we have a problem.
