    I also do not understand this business about it keeping several different back-ups 'until the hard drive is full'; why would it keep copying the same things? I only want one back-up copy of all my files.

    If that is so, then SuperDuper! might be a better fit for you. But Time Machine will give you a backup of your HD, and you can choose from which date it was backed up that you want to restore from.

    I surmise you missed this thread AliWonder: time machine slow in 10.7.5


    Quick summary: It's a bug introduced with the recent OS X 10.7.5 update.


    Prognosis: A fix is anticipated, but it's not out yet.


    ... Is there something wrong with it? Will it ever finish?


    Yes, and maybe not, respectively.

    It looks like John has the answer for you Ali.

    In regards to the multiple backups, if you don't change a file, then it doesn't get backed up. Only revised and new files will be backed up. Somehow TM knows how to sync them with all the files that haven't changed as well if you ever need to restore your system. That is why subsequent backups go much more quickly. So it won't be copying the same photos over to each new backup, just the new ones, if that makes sense.


    As I said, you may want to look into SuperDuper!. You have to manually make your backups with it however, though after the first, it too only back up the files that have changed or are new.
