time machine slow in 10.7.5

Since updating to 10.7.5 using the Combo updater, Time Machine on my iMac seems much slower. Anyone else seeing this behavior?

iMac, Mac OS X (10.7.5), iMac 21.5 in.; i5; iPad 32Gb iOS 5.

I should not be adding more repetition to an already repetitive thread, and I apologize for that, but for some of us Time Machine is not as crucial as Spotlight. Like a number of other people, I'm using Carbon Copy Cloner for my backups now, instead of Time Machine. When and if things get back to normal I'll go back to using both.


But I am being grossly inconvenienced by not having Spotlight, because I was using it in my work to search for content on my hard disks. There are other programs around that will find files by name and so forth, but none that I know of that, for instance, will find all files (including proprietory word processor files) in which some technical term is used. I've grown to depend on being able to do such searches and until there's a fix for Spotlight or I find out about some third party software that functions as well as Spotlight did on content, my work is being affected.


Yeah, I know, I could downgrade, or try Mountain Lion, but to be honest, after messing with this for a week now I'm getting tired of trying one thing after another, for fear of frying pans and fires. Maybe Apple will fix this before I also get tired of guessing which files have the term conveyance in them.

Where is progress? My Macbook Pro is not performing better in everyday utilization than my 2008 white Macbook in its original configuration. Updates come in nearly as often as for Windows and now with a major bug that is creating problems with my work.


Not to mention that the brandnew Macbook Pro went out of order (heat detector defect) after 3 weeks and I had to wait for nearly one month to get it back because parts are shipped to the service center (they were nice ...) once in a while.


I am afraid that Apple lost any competitive advantage to its much cheaper competitors and this is definitely my last purchase from that company. I can have problems considerably cheaper.


By the way, any experience with Blackberry? This is my 3rd BB in 18 months and for service now since 2 weeks just out of the box ....


Is there anything else around than rubbish ?????

Yep, Mountain Lion 10.8.2 has the same problem, at least with Time Machine. In my latest experience Time Machine wanted to back up 29.5 GB (way more than expected). After a couple of hours that many GB had been backed up but then both the limit and the backed up amount started incrementing very slowly. When they had reached just over 32 GB after a couple of hours and still incrementing I just disabled Time Machine. It will stay off until Apple does something about it.


I also run Lion on another computer and there I have also disabled Time Machine. Spotlight runs (and runs and runs ...) but at least I can still search.


Are backups made by this miserable Time Machine to be trusted? When you expect backups in the order of megabytes and it backs up gigabytes, what on earth _is_ it backing up?

I had the same issue on my macbbok 2009. but now it seems to work after i performed the following procedure


- delete the spotlight file sudo rm -rf /.Spotlight-V100


- download and install combo-update 10.7.5 from apple page


- turn off time machine and restart


- rebuild spotlight index (it took many many hours!!! i guess the whole night)


- deactivate spotlight sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist


- turn on time machine and make a backup (it took some minutes for 11GB)


- activate spotlight sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist


Time machine works.


I hope the commands are correct.
