    Okay, so reporting back already.  Using an external drive, connected to my Time Capsule, for a backup is proving to be very unreliable, which is about the worst thing when you are wanting a safe back up.  Right now, I am having the following issues:


    • Takes ages to connect.
    • When it finally does, it only has one back up.  No incremental back ups from earlier.
    • After restart, going into Time Machine, more back ups appear, but only one for each day.

    Again, not normal.  That sometimes seems a bit slower than to the TC's internal HD, but otherwise works well.


    With the USB port being underpowered, however, many folks find they need a powered USB hub.  One will, another won't, with the same make and model drive.


    I don't know why you're only getting one backup per day, but the logs should show that.  After 24 hours, though, they're automatically reduced to one per day (the first).

    Just to be clear, the drive plugged into the TC USB port is a powered drive, so it's not relying on the USB port for it's power.

    The USB port is underpowered. Many folks find they need a powered USB hub even with a powered drive -- the larger the drive, the more likely to need a powered hub.  


    It's also possible, of course, to have a problem with a port, cable, or drive.  Cables can have hidden faults, a plug that makes good contact in one port may not make continuous contact in another.



    To further test, I have also backed up my Macbook Pro to the external TC connected drive.  In that case, it all worked well, but the only strange thing is that the sparsebundle file is indicated as only 52 GB, but my Macbook drive is about 320GB full.  When I go into Time Machine on the Macbook, the backups appear nicely and are fairly responsive, exactly as I would hope.  The files all seem to be there, so how can it possibly be a full backup of a 320GB drive and yet be only 52 GB?  Is my finder info showing the wrong amount?  The Macbook is plugged in with ethernet right now and it's not backing up anymore, suggesting it has finished it's full back up, but has it?


    Thanks for reminding me about the back ups reducing to daily after the day today, but I am still only getting one back up for this day on my Imac and Saturday and Sunday are not there at all.  It jumps back to Friday.  As you say, not normal, so still don't know why that is.

    For both of those, look a the messages, either via Console (filter for Backupd) or the widget in #A1 of Time Machine - Troubleshooting.   See if the backups completed normally; if so, how much it showed as being backed-up.  Use one of the apps in #A2 to see what was backed-up.

    So in your tip about speeding up the first back up by connecting, you say:


    Disconnect all users via Airport Utility > Disks


    So I go into airport utility and I do not see a command called "disconnect all users".  Can you explain more clearly where I find this specific option? 

    Apple, in it's infinite wisdom, removed that button from Airport 6.   


    We've been after them to do something, anything, about that on ML for over a year now. Please add your voice at:


    If you're the only user of the TC's disks (internal and external), just power-cycle the TC.


    EDIT:  #Q2 does mention that Airport 6 doesn't have that button, and provides a couple of workarounds.
