Time Machine Replicating
I have a MacBook Pro and MacMini, both recently updated to El Cap. It's been a while since I last used Time Machine and recently set up on both machines.
I have a hard drive connected to my Airport Extreme router and used as an air disk. I have not issues with using the disk and can see the device on both machines.
My problem is specifically with Time Machine machine back up on my MacMini. I was able to set up and TM ran for several days then this morning, it showed that there was a successful first backup. Looking on my air disk, it now shows the original parse bundle MacMini and MacMini 1 so it looks like it did not see the the first backup and then decided to create another one.
I see an error previously, and I don't recall the exact message but it was some like "the original folder/disk has change" but that was a couple days ago but that has not since returned.
Thanks for any help.
