Time Machine 'growing' during backup.

I've had this issue before, but has only just become a problem.
Basically, Time Machine starts, and (in Console) says it needs to backup 28.2MB of files ... here's the console text:
29/08/2012 18:53:09.181 com.apple.backupd[27535]: Will copy (28.2 MB) from iMac
29/08/2012 18:53:09.191 com.apple.backupd[27535]: Found 455 files (28.2 MB) needing backup
29/08/2012 18:53:09.227 com.apple.backupd[27535]: 403.3 MB required (including padding), 16.93 GB available
However, when it backs up, this size grows (it's currently counting up from about 6.95GB) until it says there's not enough room on the backup disk. If it only needs 28.2MB, why is it appearing to do a full 'first' backup?
I now cannot backup via Time Machine, as it's saying that I don't have the space. I've tried deleting the 'in.progress' file from the backup disk, and the .plist file from the root Library directory – but no joy: it still gets bigger and BIGGER.
Any one having the same issue?

I've heard virtual machines can cause issues, but I don't have any!
The only solution I've had is to manually (via TM's interface) a handful of my oldest backups. Afterwards, it backed up 58.4Gb and is working okay at the moment.
As with your backup, it said it was backing up much more than this (around 90-100GB), despite only copying 58.4Gb. I think it's just a case of TM not deleting outdated backups effectively when disk space is tight. My TM disk was rather full – but I hoped TM would deal with that!
I'll keep an eye on it, as much of what is backed up I wouldn't consider 'new' or altered files (many of my Apps, for instance, in the last big backup. Whether this is a Mountain Lion issue, I can't say, as it's taken two years to fill up my disk, so it's seen a few system migrations in its time.
Anyway, I'll keep an eye on it and see what happens when my free TM space gets to around 30Gb (which is when the problem occured).

Time Machine Freezes During Backup!

Hi there,
When I back up my computer for the first time using Time Machine, it gets to around 53.2 GB. After that, it sits there with the blue progress bar at the same level. Then, i get a message that says I did not eject the disk properly, and then Time Machine alerts me that it could not finish the backup. NOTE: When it says the disk has not been ejected properly, I still see the disk in both Finder and disk utility. Also, I currently have the disk in 2 partitions, but I'm only using the Mac OS X (Journaled) partition for my Time Machine backups. Please help! Like I said, it seems to eject my external hard drive (Hitachi 250 GB Simple Drive) after freezing up for a while. I am able to use other things on my computer the whole time. The only application that was open during the backup was iTunes. Here is the log from Time Machine buddy:

As a first step, launch Disk Utility, select the backup volume, and run "Verify Disk" (NOT "Repair Disk"). It will take a long time to run, maybe hours. If any errors are found, copy all data on the device to another drive, then run "Repair Disk." Be prepared for the possibility that "Repair Disk" may destroy the volume beyond recovery. It may also fail to repair the damage, in which case you should replace the device -- DO NOT erase it and continue to use it.

Time Machine stuck during backup

From December 28 to January 13 my Time Machine functioned without issue, using an external Seagate Free Agent Drive (300 GB) with a 150 GB partition devoted to TM. For whatever reason I didn't happen to connect the drive from the 13th to the 16th, and now it appears to be freezing during the preparation process or very early in the backup.
I've looked at some of the non-complete packages to try and ascertain the problem - so far it appears to always hang while backing up the Applications folder. Why it is re-backing up this whole folder at once is beyond me, as I'm only aware of one program I've recently updated - Flip4Mac. Incidentally, this was the program is was halting on initially - so I added that to the exclude list. Next go at it, and its stuck on a different program. Then another. Then another.
Do I really need to exclude my whole Applications folder? That seems a bit counterintuitive to me.

I've discovered the culprit after some additional searching here. Apparently Time Machine does not function correctly while the iSight is enabled. In the past I've had no trouble with Time Machine running in the background with a variety of other processes ongoing, but apparently this one is problematic. After quitting Skype I've found that backups completed quickly and painlessly. Hopefully this post is helpful to others as well, and hopefully Apple addresses this - at least through improving Time Machine's dreadfully horrible Help files.

Time Machine stalls during backup to external HD

About a month ago, Time Machine began to stall when attempting to backup to my external HDD. Now when I attempt to backup, the progress will reach ~3 KB/4GB and will stop. I have no idea what the problem is or how to fix it.
I have tried running repair disk on my external hard drive, i was able to backup to the point of 1.58GB/4.09 GB before the progress stalled. I performed a search in console for "backup" and found an error that occurred 3 hours after the backup was started. This was the error "7/28/12 3:15:00.439 AM com.apple.var-db-shadow-backup: Error adding file shadow". I dont know exactly what it means or what to do about it.

Time Machine crashing during backup

I have been having issues with TM for the past 2-3 days. It worked fine for the past year and has suddenly stopped working and generating errors after every attempt. I have verified, repaired permissions on both my internal HD and the Lacie 1 TB external drive (partitioned into 2x500G, one for TM and one for media). I have also erased the partition and resetup TM but still no luck. The backup seems to fail after copying 1.8GB of data of 178 GB. I have attached a copy of the log from Time Machine Buddy.
Thanks for any help.

Going to give the hardware test a run to see what it comes back with. I am quite confused as I am not seeing any other issues with the computer.
I have been working on computers for years and still do it for a living and can't figure this out for the life of me (The reason I use a mac is because I deal with PC issues all day long). I honestly am considering doing the actual complete wipe and reinstall even though its probably not going to help. I'm at a loss here and its frustrating because I deleted all my old backups as I originally thought it was the HD causing the problem and tried formatting the drive.
Thanks for all your help...Your assistance here is invaluable and you are great at articulating troubleshooting steps.

Time Machine error during backup

After using my external USB drive as my backup target for several months I am not getting the following error:
Unable to complete backup. An error occurred while copying files to the backup volume.
My backup volume is an external USB formatted Mac OS Extended (Journaled). I've reformatted and verified the external disk. I've also checked the permissions and verified my startup disk.
The same thing also happens on my firewire 400 external disk. I've tried the same things on that one.
Any one got any ideas? Thank you in advance.

You might try looking in the console log. Use the Console application in your Utilities folder. Look for entries related to the backup to see if there is more information that could give you a clue to the cause. In addition to a problem with the backup drive, the error could be caused by a corrupted file you are trying to back up.

When time machine does a backup I get an error message

Added a new Seagate 3T external as a backup drive Every time Time Machine does a backup I get an error message that the disk was not ejected properly, no bid deal just a pain. System 3.5GHz Intel Core i7... 16GB DDR# memory ... OSX 10.8.4. How do I get rid of this error??

Notes/Tips on OS X 10.8.5 External Drive Eject During Sleep:
Updated the previous page on OS X 10.8.5 Problems/Notes and Tips with more info regarding external drive 'eject' in sleep and on drives going to sleep/spinning down despite ES settings. I ran some tests with drives I had but so far have not seen those problems with my setup/drives at least. Apparently many have based on the still growing number of threads on the subject in Apple's Mountain Lion forum.
... you posted inaccurate information about a Mac that I pointed out.

Time Machine freezes during back up to Passport Ext drive

Time Machine freezes during first back up to My Passport Ext drive. It is a 1TB, and seems to keep stopping at 6 to 10GB stage so never actually backs up. I have excluded files to limit first backup to about 40GB.

you sure this is a Mac Pro and not a MacBook Pro first. Most every report of issues with bus powered like Passport are best solved using a drive case with its own power instead.

Hi,
I am using an encryption software to encrypt some folders of my account (called Kryptospace: http://www.cemacsoft.com/products/kryptospace/kryptospace.html)
So here is the situation:
* In Documents I have a folder called Private, this folder is the mount of an encrypted DMG (Located in ~/Library/Application Support/Kryptospace).
* I have got Spotlight to reference this DMG - which works fine
* By default TM set the folder as Excluded so I removed that from the Preference Panel
* But I noticed that Time Machine does not backup the data within the folder
Do you know how could I get TM to backup this folder, I don't mind if it's not encrypted since the backup is secured (unlike a laptop that I could lose).
Thanks & Regards,
Daniel

Daniel,
As long as Time Machine is backing up the disk image, itself, it is keeping your files backed up. The only problem with this scenario is that the entire disk image file must be re-written during every backup for which files inside the disk image have changed (the disk image file will have been modified, so a new, complete copy is backed up). This is less efficient from the standpoint of disk space usage.
What I have posted above will hold true, as long as the third-party software doesn't do something odd with the disk image. You are aware that there really is no need to use a third-party solution to do something that OS X, by itself, can handle quite well? You could create your own encrypted disk image using Disk Utility, store it somewhere convenient in your HOME folder, then create an alias that points to some location inside the disk image, and the results would be the same. If you included the key (password) for the image in your Keychain, access from your account would be seamless and transparent.

Time machine won't backup, yet plenty of space & not much used on Mac HD

Well, this is yet another "Time machine won't backup becuase there is not enough space" thread. I have searched Google and threads here but it's still a mystery why this error is occurring and it seems there is no clear solution. I also looked at the Apple Time Machine errors FAQ as well.
Here are my specs and what I have tried so far.
2010 Mac Pro Quad Core with 1 TB hard drive with 12 GB RAM. (137 GB used so far on internal Mac hard drive disk, so about 863 GB free space).
- New external 1 TB hard drive initialized as Time Machine backup disk when inserted for the first time.
The exact error I am getting is this: "This backup is too large for the backup disk. The backup requires 1.80 TB but only 999.20 GB are available."
I have tried deleting the Time Machine system preference, reinitializing the external disk, clearing the system caches with Cocktail, restarting and letting Time machine ask me all over again if I wanted to use the external drive for Time Machine. Still the same error.
My question is how on earth can 1.80 TB be required for the backup when I only have 137 GB of used space?

Two possibilities:
There's another disk (or disks) connected to your Mac. If they're formatted HFS+, Time Machine is trying to back it/them up as well. You can exclude them per #10 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum). The 1.8 TB includes 20% for temporary workspace on the TM drive, so TM is estimating the backup at about 1.5 TB.
Something on your internal HD is corrupted, causing an incorrect calculation. Verify your internal HD, per #6 in [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html] (or use the link in *User Tips* at the top of the +Using Snow Leopard+ forum).

How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac

How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac?
The question pretty much says it all.
I have a Mac Mini with an attached 3TB Hard Drive used for Time Machine Backups.
I have an Airport Extreme base station which services that machine plus several others.
I would like to backup my new iMac and a MacBook Pro to the Mac Mini.
What do I need to do on the mini to export that hard drive so that it can be used as a Time Machine target from the other systems?
All systems are running 10.6.8.

Well you would have to do backups over a network which is much slower and has highest chance of becoming corrupt. I think your best option would be to get an apple time capsule to act as a network and back if thats how you wanna do that

HT201250 Can I recover the backups from Time Machine, but the backups is deleted by the Time Machine!

Unfortunately, the Time Macchine deleted my oldest backups in my hard drive.
I have the important files in the backups.
So hope someone could help me to recover the backups.

Time Machine will remove old backups automatically. It tells you when it does, but of course by then it's too late.
There is no recovering deleted backups, since it was necessary to overwrite them with newer backups.
For further explanation read the following entries from Apple Support Communities contributor Pondini's Time Machine FAQ:
12. Should I delete old backups? If so, How?
20. Once my Mac is backed-up, can I delete some stuff to save space?
Time Machine is for backups. It is not an archiving utility. To archive files requires something like one of these:
Carbon Copy Cloner ($39.95) http://sites.fastspring.com/bombich/product/ccc
or
SuperDuper! ($27.95) http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html

Time Machine does not backup home/user directory (on separate drive)

I recently installed a SSD into my Mini. Due to size restrictions, my home/user directory has to be kept on another drive. I retained the stock 1TB drive that came with the Mini for this.
Ok, installed the SSD, restored a Time Machine backups (sans user data). Used a different admin user and configured my user to use the 1TB drive for it's home directory (/Volumes/1TB/home/<user>). Restart, log in as my user, all is good. All data, settings, etc is there. Everything looks normal.
Time Machine REFUSES to backup this directory. It will backup the 1TB drive and anyting else I create in it, but not the home directory. I tried every permission trick I could think of or found online. I even tested it further by formatting the 1TB drive fresh, adding a new user, configuring the user to use the 1TB for their home directory and it still won't back it up (this was a test of permissions the OS set, to make sure I didn't change my data perms somewhere along the way). Time Machine would not backup the new user's home directory on the 1TB drive.
Any thoughts? I can't be the first person to have their home directory on a non-OS drive.
If I were to create a folder/file in /Volumes/1TB/<test file> ... Time Machine gets it perfect. It just will NOT touch /Volumes/1TB/home/<anything here>
Thanks!

Open the Time Machine preference pane and unlock the settings, if necessary. Click the Options button. If there is one particular folder with items that are not being backed up reliably, add it to the list of excluded items. If there are many such folders, add your home folder to the list, or add a whole volume (i.e., what Apple calls a "disk.") Save the changes.
Start a backup, or wait for one to happen automatically. When it's done, open the preference pane again and remove the exclusion(s) you made earlier. Back up again and see whether there's a change.

HT3275 Time Machine Error: The backup disk image "Volumes/Data/My Macbook Pro.sparsebundle" is already in use. (How do I correct this issue?)

Time Machine did not back up:
Time Machine Error; ("The backup disk image "/Volumes/Data/My MacBook Pro.sparsebundle" is already in use.")
How do I correct this issue?
Thanks!

You need to be careful Bob.. people might take this literally.

Time Machine fails to backup HD and stalls computer when backing up to external HD (Western Digital WD5000MT) when using Firewire 800 but works fine using USB

I have a mid 2012 MBP (MacbookPro9,1) running Mountain Lion 10.8.2. When I start a Time Machine backup to an external Western Digital HD (WD5000MT) connected using a Firewire 800 cable, my open programs stop responding and in general my computer freezes up not allowing me to open activity monitor or the console utility. I can't even shut down or restart my computer and must hard boot to reset. Though removing the firewire cable that goes to the external HD can sometimes get my system working again. However, the WD external HD also has a usb port and when I connect it to my computer via a USB cable, Time Machine seems to backup my system fine without stalling my computer. This same external HD worked fine with Firewire 800 using my old late 2007 MBP running snow leopard. I should note that my brother has the exact same model WD external HD and he also had issues with the firewire port on his MBP running mountain lion. I have run the disk utility checking for disk/file permission errors and the drive itself seems fine. I initially formatted that drive as ExFAT but while troubleshooting reformatted to HFS+ and still had the same issue. I tested using a different firewire 800 cable but still had the same issue. Can't think of anything else to do. I don't have another firewire-compatible device to test if it is the HD vs the firewire port. I would prefer to use the firewire port for quicker transfer speeds but I'm stuck with USB for now. Any suggestions?
