Having installed my second 2 T Time Capsule in less than a month after the first was replaced due to some faulty wiring or something (the Apple-certified technician determined that but wasn't specific about exactly what was wrong), I have clocked 11 hours for it start backing up and 8.5 hours for it to back up 2.9 GB of 80.13 GB. It's ethernet-wired to my iMac running Snow Leopard, just like the last one. At this juncture, I can only conclude that one faulty unit was replaced with another. Comments welcomed.


iMac, Mac OS X (10.6.8)

    That's terrible.    Something is very wrong.

     

    The speed will vary considerably, depending on what's being backed-up at the time (OSX and apps, the first things backed-up, contain zillions of mostly very small files -- since a lot has to be done for each item, those will run much more slowly, per GB, than things like a bunch of video files).

     

    But overall, you should see something on the order of 20-24 GB/hour over Ethernet.  If the TC was empty when the backup started, copying should have begun almost immediately.

     

    Try the things in #D2 of Time Machine - Troubleshooting to be sure it's not something else, but it sure sounds like you got another dud.

    I have seen really slow slow speeds and it is hard to determine what is going on. But I think to get two duds in a row is stretching the limits.

     

    Make sure you only have wireless running or only ethernet. I have found it really slowed down having multiple networks to the same source.. It doesn't make sense as the Mac should just choose the higher rated link.. but practice and theory is often conflicted.

     

    Make sure your ethernet is getting full gigabit speeds. ie it should link at gigabit and it shows that in Mac when you open the network preferences check the advanced box... last tab ethernet will show.. or more archane  just open a terminal and type ifconfig.

     

    You can even try just copying some files to the TC.. create a directory and see.. particularly if it slows down after a few minutes.. I suspect that might be a firmware bug.. For SL there is no advantage to any later firmware from 7.5.2, so I would downgrade the TC to that.

    The TC was brand new, so I assume it was empty. It took 11 hours to begin backing up after showing "Making backup disk available" until then. When it started "backing up" at 8 AM the next day, it was very slow. About 12 hours later, it had only backed up 3.91 GB of 80.1 GB.

     

    When installing TC, a prompt asked me to update the firmware, so I did with each one. To that, the technician nodded that I did the right thing.

     

    I went through all the prompts to make certain that it was only configured to ethernet.

     

    He figures two in a row means there's something wrong with my computer and wants me to bring it in to check it. I think I got another dud TC. The store tells me that 10% of the TCs they sell don't work. The Apple tech checked the previous one and found it to be very slow, which is why he replaced it. He didn't check the new replacement, but will be later today or this week. I wondered if the problem was with the new ethernet cable I used. He said it wasn't. He wondered if maybe the port is at fault. I doubt that since it normally serves my internet cable and was just checked for speed.

    Nothing's perfect, but if that's even 10% true, Apple's got a big hairy problem.

    That's probably true, but sometimes, a plug that makes good contact in one port may be marginal in another.  I've fixed slow or intermittent connections by just swapping ends! 

     

    Keep us posted.

    Same replacement TC was tested by Apple tech and worked fine, so I bought a new ethernet cable and tried again. As before, I connected my internet cable to the TC. It took 11 hrs to begin backing up. Then, after I turned on my desk lamp, the message was "Backup failed: Make sure backup disc is on and on the same network". I tried again via "Back up now". After 12 min of "Making backup disc available", it started "Backing up".

     

    While working, I noticed definite hanging on the opening of applications and Web browsers. Today, it's still not backed up my drive. All told, it took from May 20 to June 2 to back up 40.9 GB, or about half the drive.

     

    I called the store and was told that the problm must lie with my computer and that it should be brought in for possible repir along with the TC.

     

    Now, to find a kettle that lasts more than a two years, which is a whole other story. I've gone through 4 coffee grinders, two toasters, and sunrdy other small appliances in the last 4 years with all of them breaking down. I can't be alone in complaining about products that don't last like they used to. Consumers are at war with mfgs who don't care and governments who could care even less and software and computer mfgs are no less at fault with products not ready for mass consumers but that they foister upon us anyway. Just look at the postings at any hardware or software blof-come-discussion and it becomes all too obvious. I've been using the beasts for over 20 years and the matter has only grown worse.

    Could be, if your Mac is also slow when Time Machine isn't running.  But that's just terribly slow.

     

    You might also want to double-check the green box in #D2 of Time Machine - Troubleshooting.

    At the Time Machine troubleshooting site, I see mention of antivirus software as a possible problem and that it should at least be turned off. I asked that of the Apple tech who said it wouldn't be a problem.

     

    At this point, Idon't know what to do and just need to do a back up. Trouble is, I can't any longer because now my other back up drive isn't being recognized, even after using different ports on the external hub and restarting over and over again. I turn it on and it soon stops whereas it used to appear as a icon on the desktop. It also doesn't appear in Disk Utility window.

    If you mean a Genius, they don't get a lot of training on Time Machine (and don't use it in the stores). 

     

    It's mentioned here, among other places: Mac OS X 10.5: Time Machine may display "Preparing" for a longer time.

      

    Even with the TM drive excluded, we do see problems with some anti-virus software slowing backups to a crawl from time to time; that's why it's listed on that page.

    That sounds like a problem with the drive.    Try different port(s), cables, and combinations of the two (a plug that works fine in one port may not make good contact in another - if you only have one cable, try swapping ends).   If that doesn't help, disconnect it and power it off (if it has its own power) for several minutes.  Be sure all plugs are snug and secure.  Restart your Mac, reconnect, power it up and try again.  If it still won't appear, it's almost certainly failed.  Last resort, see if a different computer can see it.

    To think that the anti-virus softwarre could have been the problem all along is troubling to say the least. Maybe I should try again before taking it and my computer in, as they suggest.

     

    The store does use Time Machine and TC for their backups.

     

    A problem with the drive? It may sound like that, but am tempted to blame Apple. It worked fine until TC was installed. I tried all the suggestions you make and it's still not being recognized.

    Did you try unintstalling it, turning it off, or at least excluding your backups earlier?  If not, it's worth a try.  There are many threads here where one AV app or another has played havoc with TM backups (and other things).

    That's new or unusual; most don't, or didn't a year or so ago.  

    But good -- maybe they'll begin to learn more than the basics about it.

    Installing a TC won't have any effect on an external HD (unless you connect it to the TC).  If neither your Mac nor another computer even recognize it, it's likely failed.  If it has it's own power supply, it could be that.

    I tried turning the antiviral software off and backing up, but TC was just as slow as before.

     

    The external drive is about 4 or perhaps 5 years old. The way things are made these days, it could be that it's death is simply coincidental.

     

    Later today, I will relace it with something else. It will be interesting to see how long it takes to back up my drive from start to finish not using Apple's TC.
