As suggested, I looked at the console logs (searching on "backupd"). No wonder it seems like TimeMachine is always running. It took 41 minutes to backup about 40 MB. It does this every hour, so it's running for 41 minutes and resting for 19 minutes. It sure seems to backup a lot of files, co

Thanks for the suggestion. I will try this when I get home. I tried this at work, just to see what it looked like. I was surprised to see that it claimed to backup 43,000 files, though it only took 2-MB of space. That's an order of magnitude more than the 4,500 files in your output. Also, i

Hi, I do not know of any large (or small) SQL databases. I just opened the Console app and found one message repeating itself every second. There were thousands of copies of the same message, but I have no idea if it's related to the TM problem. The messages said: 3/7/12 10:30:40 PM com

Hi Chad, Both the TM drive and the source drive are 3-TB. I am not at home right now, but I'm pretty sure that both have more than 2-TB of free space. Even if the source drive has 1-TB of files, I bet that more than 500-GB are excluded (due to not backing up Movies, Music, Pictures), so my gu

Thanks for confirming that you had the same problem, and that it was a disk failure in progress. I think the first thing I'll try is to replace the TM drive and see if this all clears up. Thanks, Gregg On 7 Mar 2012, at 2:49 PM, Nathan Sims wrote: > Check your system and console logs. This h

Check your system and console logs. This happened to me, too, where TM would run and run and run. It turned out to be a disk failure in progress (on the TM drive). Unfortunately for me, it was too late to save any of the data on the drive. On Mar 7, 2012, at 11:06 AM, Dinse, Gregg (NIH/NIEHS)

Hi Mike, I looked at the Activity Monitor and I forget the name of the process, but it looked like one that I thought was associated with backups, so I did not notice anything unusual. I'm pretty sure the CPU is not overloaded and that the memory is not used up. Both the TM disk and the system

Hi Matt, I was worried about a hardware problem. As you say, either the TM disk or the system disk could be failing. Both are very new (3-TB Seagates). I have not yet looked for information in the Console app, but unless it's very obvious, I probably won't recognize a problem even if it's the

Greg, Is it possible you have a hardware problem? Perhaps the TM disk or the source disk is failing, and the backup is taking so long because of difficulties reading or writing files. Is there any useful information in the Console app? The only time I've seen TM consistently take this long is

Both machines use an internal hard drive for the TM backups. Both TM backup drives still have a lot of empty space, though the TM drive at home is larger than the TM drive at work. I certainly have a few files at home that are larger than those at work, such as videos, but I exclude the Movies
