I have a 1TB TC and a 1TB WD USB drive.

A couple of months ago I ran a TC archive to the WD. It took a while (about 600GB of stuff). As I recall it was pretty much over night.

I wanted to archive the TC again so I deleted all the stuff on the WD - that took awhile. Not working with USB drives I was surprised I could not see the USB drive with Disk Utility. But eventually everything went in the trash and was deleted.

I tried to archive again the TC to the USB attached WD and it starts off fine. However after about 12 hours I am only at 95GB out of 562GB and it looks hung. This is the second time this happened. In two days - yesterday pretty much the same thing - i.e. hung about 25%of the way through.

When I launched Archive the second time I was extremely careful to look at all indicators to see that the WD was empty.

What causes Archive to hang? What transfer rate seems logical?

    It's much faster to connect the drive to your Mac and use Disk Utility to Erase it.

    It will be very slow under the best of circumstances. The data has to go from the TC's disk to your Mac, then +*back through the TC+* to the USB drive. So connect via Ethernet if at all possible.

    If there are directory problem on the TC's internal disk, it can be difficult or impossible to copy it. If you have Time Machine backups on the TC, do a +*Repair Disk+* on the sparse bundle, per #A5 in the Time Machine - Troubleshooting *User Tip,* also at the top of the +Time Machine+ forum.

    Depending on what sort of data you have on the TC, you might want to explore alternatives.

    That's interesting. Many folks do complain about how long it takes to archive their TM backups that way.

    I had both Apple and one of the "civilian" TC experts in the forums help me draft the Using TIME MACHINE with a TIME CAPSULE *User Tip.* And the Apple fellow helped me word that very part of the green box in #Q6 there.

    Since that FinerThings article is very recent, I wonder if perhaps the function has been moved.

    And I notice that Apple's http://support.apple.com/kb/HT1281 has been updated recently, too. I don't think the earlier version mentioned that you can quit AirPort Utility while the archive is running.

    Have you confirmed that you can sleep or restart your Mac while an Archive is running? Any idea whether it's the same for Leopard and/or various versions of Airport Utility?

    Yeah, and Repair Disk on a sparsebundle seems off the mark also - on this symptom. The sparsebundle transfers as a file. Kind of like a .dmg will move as file even if it is internally corrupt.


    We've seen threads where folks were having trouble copying TM backups in sparse bundles; doing a +*Repair Disk+* solved it (when DU was able to repair them).

    I'll fire off the archive again and see if I can close APU.


    Try Mac Sleep and/or a Restart, too. (If Airport doesn't do the copy itself, but starts a process on the Mac that's doing it, being able to close Airport Utility once it gets started won't tell us much).

    Thanks.

    No issue


    Huh? What does that mean?

    Time to update your note
    can you not test also


    No, I don't have a Time Capsule -- Airport Utility with an Airport Extreme is similar, but has no Archive facility. That's why I consulted with a very experienced user who has one, and Apple.

    If you think about it d d is the only thing that makes sense.


    What is "d d"?

    running all this data through the computer would be nuts.


    Doesn't mean that's not how Apple does it (or did it).

    just shutting down the machine actually does not disprove d d.


    So did you either sleep or restart while an Archive was running, without killing it?

    If so, you're on Leopard, right? What version of Airport Utility?

    recommend you do your own testing


    I'd love to . . . if I had a Time Capsule! Want to lend yours?
