Time Machine backup very slow in Lion

After installing Lion Time Machine backup (not initial one which is long by default) takes about 40 minutes vs. about 5 minutes in Snow Leopard. Very annoying because it slows down my entire system for such a long time. Any help, please?

Mac mini, Mac OS X (10.7)

Lion has been a disaster for what it did to Time Capsule and my backups.

I ended up doing a "hard reset" of TC, and at one point, it said that my backup would take, 1.6 MILLION DAYS....4,400 years.

This waffled (plus or minus 1,000 years) for hours, until I stopped backup, and started again....then I got it down to 16 days.

I am going back to an Apple store this wek and DEMANDING my money back for my TC, or at least a new TC.


It's not like I've used some third party software, and deserve a few problems. I've been loyal to Apple, and after being forced to LION, if I wanted iCloud, I can't believe another Apple product is now deemed bordrline useless.


I'll let you know how it went.

hi guys,


till yesterday had the same problem as you have now – I had "preparing backup" and "indexing ..." messages last like 20 minutes for very small backups (like 70 megs) before they actually start...


I went to System Preferences -> Spotlite and choose not to index drives and/or parent directory of where the .sparsebundle is. Actually I even dragndropped the timemachine share to the window of spotline exclusions, while TM share was mounted (I turned off TM and mounted it by double-clicking on .sparsebundle file).


Maybe this won't help all of you, but I'm sure, for most of you this will be the solution. Hope so.

Had the same problems. Fiddling with spotlight didn't do anything useful, and the disk utility said my disks were fine. Tried to download and install this: http://support.apple.com/kb/DL1505?viewlocale=en_US&locale=en_US which was just released on March 6th, also didn't do anything AFAIK.


At the end just gave up and reformatted the time capsule. Backup is going fine so far, but since it is the first one I have to wait 5 hours to see how it goes.

I noticed that everytime after 3 or 4 months something happens to the TM backup, whether it is that OS X goes in sleeping-mode during backup or changing user during backup, I can't find out. Things were going great until a few days ago, when extended indexing before and after the TM-backup started again, making the backup take more than half-an-hour, each hour.

I erased the backup volume with Disk Utitility and started a fresh TM backup copy (took 7 hours) to the same volume. Now it's OK again.

I wonder what the trigger is to go off like that. Before, Disk Utility gave no problems with disk.

I was having some annoying slowness problem with a TC -- wireless very slow, time machine backups taking forever. It seems that the TC was overheating, I did a terrible, shameful alteration on it and it is working now without overheating -- 10 days without slowness problems too.


Please see kludge here: https://discussions.apple.com/thread/3726265?answerId=17889208022#17889208022 but be advised, it is ugly.

Hi all,


Same happened to me. It was running flawlessly and within reason in the past, even after the update to the latest OSX. My system has always been up to date. The change happened after I installed FINALE the music software alongside with ARIA PLAYER and INSTANT ORCHESTRA and GARRITAN PERSONAL ORCHESTRA.

Without wanting to fingerpoint, it really looks like that's where the problem sits in my case. Before that everything was running like an angel.

I am using Thunderbolt external HDs and the backup is taking place in less than a KB/S speed. Not exaggerating! Currently it says 1'997 days and it is at 9,4mb since at least the last few minutes. The full backup has been initiated this afternoon - meaning some 6hours ago. That's about 1mb/hour.

Maybe the complexity of the program got it confused because indexing all these files is a hassle to Mac? Really no bloody idea. I thought the problem solver was: Delete the external HD and do a full backup. Shoudn't have....not it will take a few years to complete a backup which is out of date when finished 😝

APPLE: Please have a look. Need my feedback, no problem, call me.

Thank you!

Jeffrey

I have read most of this thread, and I have not quite seen my exact issue. I installed the TM widget, because my backups seemed to stall at 5 seconds, but after trying again, I simply get the moving progress bar, saying "Backing up...". It's been that way for about 24 hrs now, and the TM widget is showing something:

It adds another line about every hour. However, these lines don;t make any sense. Copied 161.1 GB of 0 bytes? and 825574 of 114621 items? I think someone at Apple must be smoking something 🙂 Can't wait for this to be done, so it can get stuch at 5 seconds again.


Anybody seen this type of progress before? Perhaps this really is a time machine, and it works backwards.

Just an update. After the excruciating experience of fighting with TM all last weekend, to the point that I was calling it the WTM (Waste of Time Machine), I just let it do it's thing as detailed above. After this, it seems to be running fine. It has completed many backups since then, some as quick as 1 min 47 seconds. This is being done to a MyBookLive over wifi. I am hoping this does not corrupt over time.

Hi all,


for me, the problem is solved now.

After letting it run overnight, for two nights, backup is finished and now running normally.


It was stuck inistially at 84kb and after 5 minutes went to 128kb....and then suddenly it got back to normal speed, adding some gigabytes swiftly, then got stuck again and so forth. In the end it's finished and hope you're having similar luck!


Cheers


Jeff
