While you got the same type of message as while(fork()) it's not clear to me that they represent the same underlying problem.
In your case the Time Capsule and the actual Backup seem to mount OK as seen here:
Aug 14 18:33:20 Robert-Schattners-iMac /System/Library/CoreServices/backupd[301]: Network volume mounted at: /Volumes/Time Capsule

Aug 14 18:33:25 iMac /System/Library/CoreServices/backupd[301]: Backing up to: /Volumes/Backup of iMac/Backups.backupdb
What follows indicates to me that the backup proceeded. Once it decides to do a deep traversal,it take s Loooonng time.
Aug 14 18:33:31 iMac /System/Library/CoreServices/backupd[301]: Node requires deep traversal:/ reason:kFSEDBEventFlagMustScanSubDirs|kFSEDBEventFlagReasonEventDBUntrustable|
What happened after this?

Time machine latest backup

I have a problem with time machine. I have just got a new computer and installed a backup, which was done some weeks ago. This backup was older than some backups on the hard drive. I did not want to backup the latest backup. The problem is there is not enough disk space to do a new latest backup. I thought that when there is not enough disk space it starts going over the oldest backups. But it is not doing this, is there away to tell it to erase the oldest backup. I can not see anything in the preferences that might tell it to do this.
Please could some one help.

John,
*_Full Backup After Hardware Change / Mac OS Reinstall_*
Actually, this is normal. Anytime your hardware has been repaired, replaced, Time Machine will perform a new full backup and you will not be able to resume backing up with the same history as the previous backups. Time Machine will resume incremental backups after the full backup has completed.
To view previous backups, Control-click or right-click the Time Machine icon in your Dock or Option-click the Time Machine menu and choose "Browse Other Time Machine Disks," then select your previous backup volume. You will enter Time Machine and be able to browse your previous back ups and restore files.
While there may be ways to fool/hack Time Machine into recognizing previous backups without performing another full backup, they are rather elaborate, and for the average user are simply not worth it. Ultimately, in a couple of months, all the effort to preserve old backups may seem pointless. After all, Time Machine will eventually purge away that data anyways as it replaces it with new files.
It may simply be easier to begin a fresh series of backups while saving the previous backups until your satisfied that you have enough history built up. Then delete the old backups.
*Why Can’t I Resume Backups?*
You see, Time Machine was designed to restore your Macs’ immediate environment in case of system crashes or accidental deletion of user files. As a result, reinstalling your Mac OS system software or changing your hardware requires a fresh set of backups since older backups would not accurately represent the current state of your Mac.
Additionally, if a user has had to reinstall the system software, then resuming backups to the same set could later reintroduce the very issues that lead to the reinstall in the first place. Furthermore, maintaining backups that were started with an older Mac, introduces the possibility of restoring system files that were never intended for the new Mac.
Finally, if backups were NOT linked to a specific Mac, imagine the confusion for Time Machine in households with multiple Macs backing up to the same Time Machine device. Backups from one Mac could unintentionally be added to the backup set of another Mac. In that event, any attempt at ‘restoring’ files/folders specific to that Mac would be impossible. As a result, each backup set must be unique for each Mac.
Fortunately, it appears that new full backups are not required after a user performs an “Archive and Install”, a “Restore System From Backup...”, or an “Erase and Install” with their Mac OS Leopard install DVD. At least this appears to be the case since the Mac OS 10.5.5 update.
If you require long-term archival storage of files, then you need another backup strategy.
Hope this clarifies some things.
Cheers!

Time machine latest backup unknown

Mountain Lion Server
When viewing the panel for Time Machine Unknown is shown in the "Lastest Backup" column for each user. I have verified with each client that thier machine is backing up.
How do I fix this so the time and date of the last backup are shown instead of "unknown" can better monitor the reliablity of the backups from the Time Machine pane on the server?

I am also having the same issue. Running two machines with Mountain Lion and they report back fine, also running one machine with Lion and it reports Unknown. When I got to the machine itself though, it is saying that it is backing up every hour. I suspect upgrading Mountain Lion would fix the issue as well.

Time Machine "Latest Backup" not showing up

I am using a Western Digital 1TB Mybook as a TM Backup on my G5. It has been connected since October 2008 and still has 163Gb of free space. It is still backing up hourly and when I enter TM I can access all backups.
However, when I click on the TM icon in the menu bar, it shows "Latest Backup: --" so I can't quickly scan up there to see when it last backed up.
I've run Onyx and TTools on the G5.
Any thoughts?
Steve

Sounds like a corrupted preference file to me!
Before doing anything after this line, make a note of any exclusions you've made in TM's preference pane.
In Finder, click on "Macintosh HD" then Library then Preferences. Find the file com.apple.TimeMachine.plist and move it to the desktop or delete it. Log out of your account & back into it or restart the computer.
See if things work properly after that.

How can I check time machine latest backup before crash

My husband's iMac is in the shop. I can't remember if I set his computer to manual backup. (Stupid, I know) Anyway, is there a way to check our Time Capsule from my computer for last backup on his computer?
TIA

Yes, follow the info in pondini.. to open the backup from another Mac.

Trouble getting time machine to backup latest numbers file.

I'm able to use Time Machine to backup my macbook wirelessly to an external hard drive attached to my iMac. However, I recently noticed that I am failing to back up the latest version of a numbers file.
Has anyone noticed any incomplete or outdated files - that shouldn't be - in their number file back ups?

Well, Time Machine unfortunately is bugged beyond use for some people. It is nearly impossible to tell if TM will work every single time until Apple will take a look at their programming and fix the darn thing.
Anyways, back to the point. The problem with updated files is that TM will look for new things that are indexed as new, and by indexed as new as in the Spotlight regards the file as updated since last backup. I don't really know if this would work, but you could give it a try.
Try this:
1) Duplicate the file into the same folder with a different name
ex. filename.doc, and make a new file called filename_1.doc
2) Make sure that this file is in the same folder as the other file.
3) Back up
I think that would make Spotlight tell TM to backup the updated documents.

Time Machine starts backup then fails

I'm trying to use Time Machine to backup wirelessly to Time Capsule. It starts but then fails after about 40 Mb, telling me an error occurred.
I've browsed these forums and tried reading Console Messages, but they don't mean much to me.

My time machine back up failed because it says the backup volume could not be mounted

My time machine back up failed because it says the backup volume could not be mounted. What does that mean and how do I fix it so that it backs up?

A whole lot about Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.
Use Disk Utility to repair the TM drive. If that doesn't help, and you don't find help from the above, then erase the drive and start a new TM backup.

Time machine error - backup fails due to sparsebundle already in use

Since upgrading, Time machine reports backup error:
TIme Machine Error
The backup disk image ...sparsebundle is already in use.
Any thoughts?

Thanks russ. After the initial upgrade to Mt Lion, no backups have been made. Every attempt reports the sparsebundle error. I recently updated to 10.8.1 and a whole new set of problems have shown up which is having me question the wisdom of continuing to invest in Apple product.
I have decided to pack it in with regard to the timecapsule product, as it is just too unreliable, and certainly not worth the continued time and effort it has been taking to try and get it to work. I have instead gone with an online backup service, Crashplan. I have the backup service I am seeing and I am no longer frittering away valuable time on something that ought to just work.
Problem solved.

Can I use Time Machine to backup ONLY an external drive?

I am having problems with the internal HD on my iMac and Disk Utility is telling me I need to reformat the drive and restore from backup. Only problem is that my 3TB Lacie Thunderbolt drive I was using for Time Machine recently failed (think it may have happened during an electrical storm brownout). Yep, I know, ***** to be me
The issues with the internal HD are preventing the iMac from booting and I would prefer not to have to purchase various repair software to find one that really works such as Disk Warrior or similar ((despite it getting very good reviews). I suspect it make be HFS corruption but no way to really tell that I am aware of.
I have setup an external drive with Yosemite and booted from that so now my old internal drive is seen as an "external drive".
I am using Disk Utility to make an image copy to a new 3TB external drive I purchased. Writing the DMG is going to take some time.
What I would like to do is to set up Time Machine to backup to a separate external 3TB hard drive (the second one I purchased) and have TM create a backup of ONLY the old internal drive - not the new system as well as the old internal unit.
Is this possible and if so can anyone advise how to do this. Does not seem I can exclude the system drive I am now booted from so that it is not backed up. (This makes sense that TM would be designed this way given its primary purpose is to backup a system).
If TM cannot be configured in this way, is there another option I can use?
Thanks
Andrew

Thanks for that advice. I have heard of it but a friend who does IT support at a University nearby suggested using Disk Utility to save an image - hence this is currently underway at present. Once this is finished I will try Carbon Copy Cloner.
I have another friend who has an older version of CCC - do you know if an old version will work ok or if only the latest supports Yosemite?
Also once I have the clone completed from CCC, is the process then to reformat the old internal drive and then clone from the CCC external drive back to the internal and then reboot and trust all is well?
Appreciate your help Csound1.

Andrew

Time Machine: Mavericks backup date and time issues

Time Machine: Troubleshooting backup issues
re: http://support.apple.com/kb/HT3275
"Messages you may see after clicking the red "i" include:"
I am getting a message not listed at this page. My Time Machine fails to backup to my USB3 Passport External Drive with the error code:
"Time Machine couldn't complete the
backup to "2T PP".
The system date and time is incorrect."
I have the Date & Time preference set to:
"√ Set date and time automatically: Apple Americas/U.S. (time.apple.com)"
and it seems to be the correct time.
The Language & Region prefs, advanced, Dates tab is set to defaults but I cannot get TM to backup and the same error occurs.
How can I remedy this?

Because you have just loaded a new operating system and a complete backup occurs is my understanding.

Time Machine reports backup disc needs to be 8.78 Tb. I only have a 250Gb system drive???

Thought I'd do a TM backup before installing Mavericks. It messed up big time!
I backup manually depending on how much stuff has accumulated. It varies between a few Mb to 3 or 4 Gb sometimes more. Today Time Machine decided that it wanted to reorganise the backup in some way. I watched as the available space on the TM disk went up as TM set about the task. After a couple or three hours TM actually started to do the backup. The size of the backup being 500Gb or something like that. Several hours later of listening to my fans working flat out I cancelled the back up with TM reporting that there was 200 odd Gb to go. No warning from TM to say this was a bad idea. It had been chuntering away for something like 5 hours.
After halting the backup I thought I'd start the backup again just to see how much more needed to be done. This is when I got the report that the backup disk needed to be in the order of Tb. And the oldest backup is now Nov 2013. The oldest backup before this was way back in June 2012 (MacBookPro Rertina mid 2012) when I first bought the computer.
Entering TM I find that even that is not complete. All but a couple of applications have dissapeared as have many other files.
Trouble is I use it as an archive and happily delete files on my hard drive knowing that there is a copy in a backup that pre dates the deletion.
There is also an earlier backup from my previous machine - again as a rarely accessed archive. So that's another reason not to reformat.
I'm pretty sure all is lost and I think I just have to bite the bullet and risk not needing anything from the archive. After all I have CD and DVD backups/archives that go back to the late '90s and I have rarely needed to access them over the years. The biggest loss will be photos. ****!
Anyway. What happened? Why has TM gone off the rails? I have done nothing different to what I have done in 5 years or so. Is this normal behaviour? If I hadn't have cancelled the back up would TM have slowly rebuilt all my backups as was?
Andy

Trouble is I use it as an archive and happily delete files on my hard drive knowing that there is a copy in a backup that pre dates the deletion.
Before going any further please understand that's a very bad idea. It's beyond Time Machine's scope to do that. It is not an archival system and cannot be made to become one. Time Machine guarantees nothing other than one complete copy of the source volume's contents. Anything erased from the source becomes fair game for Time Machine to delete from the backup, the moment it requires the space it occupies.
Next: I have no idea why the problem occurred, but a first and harmless troubleshooting step is to reset Time Machine by doing the following:
Turn off Time Machine first, and make sure a backup is not in progress.
Triple click to select the entire line, then control-click and select Services > Reveal in Finder. Drag the selected file to the Desktop, or directly to the Trash:
/Library/Preferences/com.apple.TimeMachine.plist
This will not delete your existing backups.
Turn on Time Machine and reselect your backup volume. The effect of deleting that file will cause erroneous values to be shown in the "backing up xxx of yyy" messages until the subsequent backup.
If it's any consolation, terminating Time Machine as you did is not an abnormal user action and did not cause the problem. It may have resulted in inaccurate information being written to the property list, which you will fix by deleting it. It's quite possible that your backups have remained intact. Just remember that anything you delete from the source may no longer exist following the subsequent backup, and that is to be expected.

Time Machine:The backup disk ran out of space unexpectedly. .....

Hi,
I upgraded to Mountain Lion when it was released and yesterday I began getting this notice from Time Machine:
"The backup disk ran out of space unexpectedly. Time Machine will try to make more space available by removing expired backups during the next scheduled backup."
I have a one terra external hard drive with exclusively Time Machine. It says it has 3.4 gigabytes available, but isn't deleting old backups and making room for new, like before. I tried the "encrypting" solution, but it still keeps on giving me this message. Should I erase and format? If so, what option should I chose to format?
My Hard Drive has 240 gigabytes, so 1Tb should be more than enough.
Thank you!
Gloria

SuperDuper and Time Machine are two completely different backup utilities. If you want something like what SuperDuper does then don't use Time Machine. You have many other options that won't use up all the space on your backup drive:
Backup Software Recommendations
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
Synk Pro
Tri-Backup
Others may be found at VersionTracker or MacUpdate.
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
Do the following to erase your drive:
Erase a Drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

Time Machine/Capsule Continually Failing Back-up

Hi,
I have been having this issue for weeks now but whenever I attempt to back up my iMac (Mid 2011 Model, with Mountian Lion 10.8.3) it constantly fails and I have been running around these forums like crazy trying to find a solution. I bought my Time Capsule with my iMac, 2TB version. I also back-up my MacBook Pro (Mid 2012 Model) All of this started when for some reason Time Machine stopped working and I wipped everything and started again.
It is connected wirelessly to my router and to both Macs (Too far away for me to hard wire).
Here are the Logs:

Hello CaribouMaine55,
Thank you for using Apple Support Communities!
I was researching what might be going on here, and found a great article named Time Machine: Troubleshooting backup issues found here http://support.apple.com/kb/HT3275.
It is pretty lengthy but I feel has the best advice for getting your Time Machine up and running.
All the very best,
Sterling
