Time Machine "preparing backup" eternally upon wake from sleep

at a bit of a loss here...
iMac 24" (version which offered 7300GT as BTO option)
10.5.5 with all updates applied
LaCie 500 gig USB 2.0 drive directly attached.
Up until about two months ago, Time machine functioned fined. Then for some reason, the following started to happen. (no known reason, no software update related etc, that I know of)
scenario... Time Machine functions correctly EXCEPT when waking from sleep. If iMac wakes from sleep and attempts a backup immediately (e.g. more than one hour has passed), it gets stuck "preparing backup" forever. I've let it run overnight (actually as long as about 30 hours), it never stops. Finder and other programs become extremely non-responsive, machine is almost unusable. Literally, the only way out is to manually shut down external drive, with attendant warnings/errors.
What I've done:
1) deleted the time machine .plist file
2) erased, repartioned (as a single partition) external drive
3) started brand new time machine backup (takes about three hours)
At this point, time machine will backup up fine... I can force a successful backup, if I leave the machine running, at one hour it does a successful backup.
BUT, as soon as it goes to sleep, time machine is hosed.
The only workable method for using time machine is to turn the external drive and time machine off when not using it, and turn the whole shootin' match on to do what essentially becomes manual backups. These backup are fairly lengthy, as time machine also does lengthy "preparing backup", but they complete in about 30 minutes to one hour.
Given that time machine doesn't give mountable/cloneable backup, I'm probably going to go back to Carbon Copy Cloner. Still, I like the ease/regularity of Time Machine, and would use it if it works.
Any ideas?
thanks

It could be a number of things. There are lots of things that Time Machine does in order to "manage" backups -- apart from just copying data to the backup drive.
It has to manage the transition of hourly backups into daily backups and must also transition daily backups into weekly backups. Each time it does this it has to move a lot of data around. It also has to maintain indexes of everything so you can quickly find backups should you want to perform a restore.
I've also noticed that there are circumstances that can cause TM to question whether it can trust it's existing backup database... I've caught Time Machine saying that it needs to do a "deep traversal" of the backup (basically it wants to check and see what it really has) and this can take a very long time.
Still... 30 hours is an extremely long amount of time. I'm almost wondering if there's a problem with either your USB bus or your drive when they wake up such that you may be getting a huge number of retries on something that should have happened quickly.
I'd suggest you start the "Console" utility, select "All Messages" at the left, and then watch the messages being written to your log file. Not only does Time Machine log all of it's progress messages to the system.log (in more detail than you'd see in the Time Machine UI), but so do lots of other system processes. If you're getting USB bus problems the error messages would likely show up in the same log. I'm especially suspicious about non-TM related causes since you said you've already blown away your TM backups & preferences and started from scratch and you're still getting the problem.
Try re-creating your problem with the Console log messages being displayed and see if you can't see something in the log that would let you get a little closer to the root cause.

Tim

Time Machine Preferences breaks when I wake from sleep

I have recently started having a problem.
When I start my computer, everything is functioning fine. I am able launch System Preferences and open any preference pane and quit System Preferences and everything is fine.
When I put my computer to sleep and then wake it up, I have issues. If I open System Preferences, I can close it. If I click on Trackpad, I can close it. But if I click on Time Machine Preferences and try to quit System Preferences, it doesn't quit. If I try to Force Quit, I get the standard "this app isn't responding" error box.
I cannot quit System Preferences is any way. Force Quit does nothing and eventually the rest of my apps on my machine stop functioning. I have to hard reset my machine to get System Preferences back.
Anyone else seen this? I don't want to blame it on 10.5.6 but I think that this started happening after that.

So I have made a further discovery.
It is related to my non-Time Machine external hard drive. When it is connected I have the issue mentioned above, when it's not connected I have no problem. I re-formatted the drive and no longer have the issues with the System Preferences, but now, if I sleep, when I wake I can't shut down. It just hangs and I have to hard restart.
A couple of notes from the console log. When the "bad" drive is hooked up, I see the following message (multiple times when I wake up:
*kernel AppleYukon2: 00000000,00000000 sk98osx_dnet - recovering from missed interrupt*
Also, when I try to do the actual shutdown, I see this error:
*/usr/sbin/kdcmond[37] dnssd_clientstub read_all(3) failed 0/28 0*
So I feel like the issue is somehow connected to my eternal drive having a conflict with the wired network card. I am going to do some more tests.

Time Machine - Preparing backup - It's endless

My C2D Mac Mini is hanging on Time Machine - Preparing Backup for the second time since "Upgrading" to 10.5.2
I had to re-format my backup disk last time and start all the backups again.
Here is an extract from the console log:
29/04/2008 23:50:13 /System/Library/CoreServices/backupd[1094] Starting standard backup
29/04/2008 23:50:13 /System/Library/CoreServices/backupd[1094] Backing up to: /Volumes/LaCie Disk/Backups.backupdb

Does anyone recognise this? I'm a Mac novice so I don't understand what it all means. I hope I don't have to reformat and start again as I was converted to Mac from PC on the advice that "A Mac Works!"
My backup drive is a 500GB Lacie Mini if that is of any relevance. Spotlight is told not to index the drive and also the Lacie drive is told not to back itself up.
Can anyone help as it's driving me nuts!

Are Lacie really that bad? I thought that the main reason they are mentioned in these forums is that Lacie are one of the only brands of external storage that apple actively promote through their own web stores so there a good chance that quite a few Mac users will buy one. Anyway I can't afford to buy another Hard Drive at the moment and the lacie works perfectly apart from Time Machine.
The problem seems to be with Mac OS the more I delve into these forums and more importantly the 10.5.2. update which is where Time Machine appears to be providing users with a lot of troubles.
The Apple support self service on the website is far from comprehensive as I guess they want you to purchase Apple Care for ongoing support after the 90 days initial period but come on apple give us a break and sort it out or provide a support email address for specific problems!

How to stop my Time Machine external hard drive preventing iMac from sleeping?

I have a late 2012 iMac, and have discovered that sometimes (I haven't noticed a pattern of when it doesn/doesn't happen) the computer will immediately wake up after I set it to Sleep (Apple Menu>Sleep). Through elimination I have found that it is the the USB 3.0 external hard drive I use as a Time Machine back-up that is the culprit; unplugging it then allows the computer to sleep. If I unplug it, then plug it back in later on, this normally solves the problem for a while, but not forever. This same Hard Drive didn't cause the wake problem on my previous '08 iMac.
A big issue is that when the machine immediately wakes from sleep, the display stays off (until I move the mouse) - this is good from a power saving point of view, but means I don't know if/when the machine is immediately waking from sleep (I have to listen to the fan when setting it to Sleep mode to hear if it has actually woken back up).
I've searched the forums, but can't find another poster with the same problem as myself. Can anyone advise a course for me to pursue to prevent this from happening?
Thanks. Jamie

Hi Frank. Nope, I'm still having the same symptoms; the plugged in external drive (TIme Machine) will wake the machine up a couple of seconds after it winding down when put to into sleep mode. Ejecting the drive and then sleeping the machine works. After plugging it in again to do a Time machine backup, it will allow the computer to sleep soundly for the first few sessions (eg a few days of sleeping, waking, sleeping, waking, etc), but then it will then suddenly start preventing it from sleeping again after a while.
It seems I'm fortunate in my case that the display stays dark (or off?) when the machine has been woken from sleep, but this was actually preventing me from knowing the machine wasn't in fact asleep for quite some time; I only eventually cottoned on because there wasn't any delay when 'waking' my machine (which there normally is). I would then have to carefully listen to the spinning fans to know if in fact it had gone to sleep or not.
So, to summarise, unfortunately no, I haven't solved this yet. If anyone else has a solution, please let us know?
Also, I've noticed occasionally after waking that there is a relatively quiet 'crackle' sound (kind of electrical sounding) from the bottom-right area of the machine. This goes on every so often for about 30mins. I see this is also an issue with other people's late 2012 iMacs, but I've not seen if anyone has a solution to it?

Alert beep upon wake from sleep

Hello,
I seem to have a strange alert beep that occurs when waking from sleep.
It only just appeared after I applied the 10.4.8 software update.
I wouldn't be concerned but today when I booted-up my machine immediately kernal paniced and told me to restart.
It seems independent of what software is open.
I can't seem to find any start-up items that could be to blame.
Any thoughts on trouble shooting this?
Thanks in advance,
Andrew

I just repeated the beep on wake from sleep.
Here is the console system log from before and after the sleep session.

Launch application upon wake from sleep

Is there an automator that will launch an application when the computer wakes from sleep? I do video chats w/ my elderly mother via iChat. I can wake her computer from my home using WakeOnLan. However, she sometimes quits iChat so it is not always running. I would like to have some sort of automator set to launch iChat everytime the computer wakes from sleep. I assume if iChat is already running, it would not matter.
If anyone knows how to do this or if it is even possible, please let me know.
Thanks,
Randy

Gary,
Thanks for pointing me in the right direction. I ended up using DisplayWatcher as it also has the ability to run an automator application upon waking from sleep. There were some other apps that were too complicated for me -- had to enter Unix commands/code and I did not understand how to do this.
Thanks again,
Randy

Creaking sound upon wake from Sleep

I have only had my MBP (very first mac) last 1/25 and for a few days would wake from sleep totally silent. In the last couple of days occasionally it wil make a creaking sound for a couple of seconds after I raise the lid sounds kinda like gears. Not very loud tho. But since this is a refurbished (june 2012) unit I was just wondering if this is normal. My old toshiba would always make creaky gear sounding noises at wake from sleep for much longer. But since it is silent it is silent most times I was wondering if this was normal or a known problem?

If that's the case, however no one else replies to your thread, you might consider re-format your computer.
In fact I have. And this is on a freshly formatted drive unfortunately.

Airport issue upon wake from sleep

When my mac pro wakes from sleep it connects to my preffered wireless network but it has some serious issues and doesn't work. When it restarts the airport icon shows connected, but mysteriously shows a weak signal and when I try to do anything that needs to talk to the network it fails. The only way to fix the issue is turn airport off then on again and hey presto I'm back on a full signal and can surf n stuff.
I'm using a 1st gen Airport Express N basestation, which works fine as I have 5 other macs in the house (non a mac pro) that don't have the issue.
Looking in my logs i see a few interesting things, it looks like when the system is woken up it sets the country code to X3 and then fails to get a proper link. When I restart airport it sees the network uses GB as the country.
I can't be the only person with this problem.

Screen blinks/flashes upon wake from sleep. is this normal?

I just got my Macbook a few days ago and started to notice that my screen flashes or blinks when it wakes from sleep. I have searched on Google and haven't seen any one post about it so I'm guessing this is normal. This is not the flicker of brightness that other people are talking about.
What happens is: I press a key or open the lid to wake it from sleep, and then very briefly for a second I will see the screen flash on (sometimes you can see a small image of the desktop), then it is black for a second, then the screen comes on normally. The delay of the screen coming back on after the blink seems to be getting longer so I was starting to worry this might be a problem. (granted the delay of the screen coming on is maybe like 2 seconds, but its noticeable) I had a Thinkpad previously and never noticed the screen acting like this.
If anyone can tell me if I need to bring this in to the nearest store or if it is normal I would appreciate it. I don't want to overreact as this is my first Mac and I don't have any problems so far. But I want to be safe if this is an indicator of future screen problems. Thanks!!
Macbook Mac OS X (10.4.8)

Take it to your local Apple store and they will send it off for repair. Or call Apple and they will send you a box to mail it in for repair.
I took my MacBook to the Apple store for the infamous screen flicker problem and they had the logic board and the LCD replaced. Problem is gone and the screen is better than before!

Black screen upon wake from sleep when I change power state while in sleep

Hi,
I'm having this problem where my MacbookPro won't always wake from sleep.
OSX is 10.6.3 and fully updated.
I've done a lot of troubleshooting, and I can now replicate the issue 100%:
1 - Put the MacbookPro to sleep by closing lid
2 - Change power source (from plugged-in to battery or vice versa)
3 - open lid - MacbookPro will wake, but stays at black screen and is unresponsive.
Only if I change power state while sleeping will this issue show. Anyone else experincing this issue, and anygot got a clue on what to do?
regards,
Lasse

I've seen the same issue after upgrading to 10.6.3. I have a one year old MacBook Pro. I would have the screen be black after coming back from sleep or hibernate (tried both).
The workaround I found is to close the lid -almost- all the way and then immediately open it back up again, like I am catching the Mac going back to sleep and then changing my mind. For whatever reason, this has been reliably solving my issue for the last couple weeks reliably.
Only other oddity I noticed is that immediately after upgrading OS X told me that my one year old battery needed to go in for servicing...
Anyway, now all looks right with the world assuming you don't mind a quick close/open cycle.. Lovely...

Time Machine "Preparing Backup"

Am I understanding correctly (from reading some other discussions here) that there are issues with Time Machine back ups and Yosemite, and that it's not just me having these problems? Since I upgrade I am having major issues with wifi connection being dropped and my Time Machine hasn't performed a back up in 19 days. It looks as though it will but stalls at "preparing back up". When it finally stops I get an error message saying it can't find the disc. I've restored the Time Machine to factory settings and started over more than once but still get the same message. Am I doing something wrong or is this an Apple issue?

Just to be clear you are using a Time Capsule for your Time Machine backups. A Time Capsule looks like this
or this
In that case follow these instructions and reply with your results:

This basic sequence seems to have happened every time I've tried to run backup lately. Pondini's A6 mentions the deep event scan related to iPhoto but not what to do about it. Help?

I decided, based on various clues from Pondini's page, that the hard drive in my Time Capsule was failing. I started a full backup on my second Time Capsule and am currenly only using the original as an internet router.

Time Machine prepares backups forever

I have had Time Machine set up on my MacBook Pro for over a year without any problems, and all of a sudden in December, it begins by preparing the backup as it always did, but it never goes any further. I left my laptop open for 2 days and it hadn't gotten any further than preparing the backup. When I check the Time Machine settings it confirms that the last time it backed up was the beginning of December 2010. My roommate also has a Mac (both running Leopard with the latest updates), and his Time Machine is working fine. Any thoughts on what is causing this for my MBP?

Thanks for the link. I downloaded the widget and worked through a few of the error messages listed, as well as doing a restart of Time Machine (#A4). That doesn't seem to have resolved the issue. Below is a copy and paste of the widget. I understand that it's telling me that the drive is full, but it should know to make space on its own to store newer backups.

Wireless connection lost upon wake from sleep

I recently joined the 21st century and purchased broadband internet for my home. I am connecting via wireless ethernet using an original Airport card and flying-saucer type base station. All I did was connect the base station to the cable modem with an ethernet cable, plug it in, and restart my eMac. The network showed up right away and I was connected. Unfortunately, after my Mac went to sleep and I woke it up, not only was there not a connection, but there was no sign of the network.
Airport status showed it was still on, but in the spot where the networks show there was nothing. Restarting corrected the problem, but I assume only until it sleeps again. I can change the settings to make it monitor-only sleep, but I would like a more permanent solution.
What might help to fix the problem, and was there something I needed to do besides just turn my machine off and on to set up this network?
Thanks.

If you pose this problem over in the Airport or Tiger networking forums, you'll find you've stumbled into a morass of conflicting reports. There have been a disturbing number of reports of Airport connections lost in Tiger after wake from system sleep, usually not reconnected until after a restart. Some people have some success checking the box to put the Airport icon in the menubar ans using that to turn Airport off, wait a few minutes, and turn it back on, yet others have reported that only works part of the time and others report it doesn't work at all. Some have reported improvement after downloading and running the full OS X Update Combo 10.4.10 (PPC) on top of an OS updated via Software Update. And the large majority of Airport users never report any problems at all using Tiger. It really sounds like there's no one cause and no one fix.
There is a workaround: don't let the Mac go into system sleep. Use the Energy Saver system preference to set system sleep to Never, uncheck the 'put hard drives to sleep when possible' box, and set the display-only sleep to say 20 minutes. If the eMac is in a bedroom and the sleepers are sensitive to fan noise or power LED lights, that will be a problem, but likely less aggravating than losing your broadband connection.

MacBook Air freezing upon wake from sleep

Hello there! Ever since installing Mavericks, my MacBook Air freezes nearly every time I wake it from sleep. Whever I open the lid, it allows me to enter my password, and then it freezes. Other times, it will let me log in, and then whenever I try to use Safari or another application it freezes. It doesn't completely freeze, I get the beachball and everything. What is going on?

Hello there AustinJGibson,
It sounds like you are having performance issues with Mavericks.
It sounds like you are seeing some performance issues after having installed Mac OS X 10.9.
I want to recommend the troubleshooting information from this article named:
OS X Mavericks: If your Mac runs slowly
http://support.apple.com/kb/PH13895
If you find your Mac is running slowly, there are a number of potential causes that you can check.
An app you’re using may require more memory than your computer has. To see how much memory your computer has, choose Apple menu > About This Mac. See the documentation that came with the app to find out what it requires. To find out how to increase your computer’s memory, see the documentation that came with it.Find the manual for your Mac
Quit any application that isn’t compatible with your computer. For example, an application may require a different processor or graphics card. See the documentation that came with the application to find out what it requires.
To see what processor your computer has, choose Apple menu > About This Mac.
To see what graphics card your computer has, choose Apple menu > About This Mac, click More Info, and then click Displays.
Your computer’s startup disk may not have enough free disk space. To make disk space available, you can move files to another disk and then delete files you no longer need on the startup disk.Increase disk space
Quit any apps you’re not using.
If none of these suggestions work, you may need to repair your computer’s disk in Disk Utility.Repair a disk
Next I would perform a Safe Boot:
