[QUOTE="Slydude, post: 1220954, member: 131855"] There is an alternative besides continually connecting and disconnecting the drive tome the two computers. I'll leave it to youth decide how easy it is to do. If you have a Time Capsule, Airport Extreme, or other router that will allow you to attach a hard drive, you could attach your drive to that. Both machines could back up wirelessly. Here are the potential problems I see with that scenario. 1. I am not sure sure about how a single attached drive would behave if both computers initiated backups at or near the same time. Don't think I have seen anything written about that. 2. Time Machine backs up to a network device, which the hard drive would be in this scenario, the format changes from a series of folders which is what's used with a directly attached drive to files stored in a sparsebundle. That would not affect your wife's backups since hers would start that way. In your case it would mean that Time Machine would want to start a completely new backup. You can put your old backups inside a sparsebundle and have TM continue from there but I have read varying reports on how successful that is. Seems to work with recount versions of TM though it is time consuming to move the files if you already have a large backup. [/QUOTE]
