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'm considering to upgrade to Mountain Lion, however I'm going to wait a little longer before I do.


I orginially planned to wait until 10.8.2 came out and the bugs were resolved. I waited until October of last year before I upgraded to Lion. Until the 10.7.5 upgrade, I've had no issues with Lion.


You would have really thought that Apple Technical Support would know about this now and have acknowledged it - this thread has been going since Friday/Saturday.


If nothing developes by the weekend, I may consider upgrading to Mountian Lion...

maybe its' a ploy to all upgrade to Mountain Lion?


While it might look that way it's mostly a matter of self-created circumstances. iOS6 was to be released on 19 September which included features that, amongst other things, required iPhoto 9.4 and iPhoto 9.4 requires OS X 10.8.2 or 10.7.5.


@NeilHobbs - I personally don't have any issues with Spotlight under 10.8.2 although can't atest to Time Machine as TM is run from my Lion Sever (10.7.4) and not my client system. Like you I wanted to wait a little longer on going to ML and this issue (more Spotlight than TM) propmted me to make the move. Fortunately I haven't come across any stability issues but being forced into Safari 6 and its unified address/search bar is horrible!

Mountain Lion does not seem to have this problem. It appears isolated to OS X 10.7.5 only.


If you decide to upgrade though, you should first make sure you have archived your Lion system since this is often the only way to revert to it. So, unless your existing Lion Time Machine backup is recent (or you have an equivalent clone) I do not recommend upgrading simply to solve this one problem. It's obvious to me that we can do nothing but patiently wait for Apple to fix it.


I reverted to 10.7.4 on my Lion systems. Time Machine and Spotlight behave normally.

I think there maybe some issues with Mountian Lion as I've found this single post thread in the forum;


https://discussions.apple.com/thread/4348326


This is only one instance, so I can't really say.


Yeah, as iOS 6 was released everything was updated to bring the OS X elements in line. This is the first issue that I've experienced with OS X since 10.5 - so in terms of overall stability its not too bad, but its not good that this is going on now and so widespread.


For the time-being, I've disable Spotlight completely and Time Machine is working fine. I would have to consider re-enabling Spotlight and letting it rebuild its index before I performed the upgrade, but doing that would cause me to be unable to back up my OS prior.


As this is so widespread, I expect Apple to resolve this.


I'm going to keep a close eye on this thread this week - we could get it to 20 pages before the end of the week 😉

I am having the same problem with Time Machine after upgrading to OS 10.7.5.


It is now slower than cold-tar at Christmas (took 3 hours to backup 2.1 GB of a 7.4 GB backup). Before the upgrade to OS 10.7.5 it was doing that same size of backup in about 20 minutes.


I tried disabling Spotlight, as has been recommended in this thread and elsewhere (http://osxdaily.com/2011/12/10/disable-or-enable-spotlight-in-mac-os-x-lion/) but that didn't work for me.


I called Apple Support and they are beginning to be aware of the problem.


I recommend all users that are having this issue reply to this thread as soon as possible.


Then maybe Apple will get their act together and issue a fix for the problem.


In the meantime....any ideas on doing a backup?
