Time Machine backup requires significantly more space than size of hard drive + external

I can't seem to figure out what is going on here. I recently purchased a new Macbook Pro with a 1T SSD hard drive, upgrading from an older MB Pro with a 500 GB hard drive. In the past I've used Time Machine to back up my hard drive and an external hard drive with RAW format photos and video footage that totals 441.56 GB. My internal internal hard drive currently is 487 GB, and I've used a 1TB time machine back up without problem to date.
I used Time Machine to install on the new system and it worked flawlessly, except that the Time Machine backups wouldn't continue. Time Machine--even when left overnight--would get hung up on Preparing Files to Back Up. So, I reformatted the Time Machine disk (lost the old backups) and attempted to back up from scratch. I then got a message that I need 3.37 TB to complete my new Time Machine back up, though the total size of the back up on disk is ~930 GB. I've read that Time Machine needs 20% - 30% overhead on disk to work well, but I can't figure out why it would require 3x the back up size. I'm hesitant to purchase a new 4 TB external hard drive as I suspect this is a software issue. I've tried reformatting the disk twice more (three total), rebooting my computer, etc. but I keep getting the 3.37 TB message. I'm operating Mavericks OS 10.9.4.
I would be grateful for insight on this.
Best,
Alex

Hi Linc, thanks for taking a look at this problem. I just reinitiated a backup to make sure it's most up-to-date. Without the external hard drive, I was able to complete a simple backup. After plugging the external in again, here's the log I got:

  • How do a clean install from Time Machine Backup which is in other partition of internal hard drive

    I have 2 partitions in my internal hard drive they are
    1. Mac OS (Sysem Files)
    2. HDD (Other Personal Documents).
    I did Time Machine Backup in HDD partition. So now i want to do clean install from the Time Machine Backup without format the whole drive since my system not booting meant that system crashed and cant boot in anyway (Just consider ). Also I have MAC bootable USB stick.
    Thanks in advance .

    Having never seen a setup like that, I'm not sure how it will work.
    In theory, just erase the Mac OS volume, then install, choosing to recover from a Time Machine backup.
    When you boot into Recovery, open Disk Utility and select the Mac OS volume, not the whole disk. Erase it, then quit DU and restore from the Time Machine backup. However, this is the part I'm not certain of. I would imagine the partition with TM backup will be mounted, but I don't know.
    If you can't see the Time Machine backup from the Recovery HD on the drive, try it from the USB Recovery stick (it is a Recovery USB and not the old Lion install USB, correct?)
    http://support.apple.com/kb/ht4718
    If you don't have a "built-in" recovery HD because of your partitioning, then you would have to boot from that USB Recovery disk.
    Your setup is severely flawed. A backup on the same drive as the data is not a backup. You will lose everything with a disk failure.
    Also, partitioning off your OS on a Mac is not necessary and is probably counterproductive. OS X is not Windows.

  • Time Machine takes up much more space than actually data backed up...

    Every time I backup with time machine, it uses up gigs of space on my backup drive, regardless of increment or decrement of data on Mac.  I could put 200 megs since last backup and TM eats 4 gigs.  I don't change the file exclusion selections at all.  Just curious if anyone knows why that is?

    I find it hard to believe I added 4gb since last backup.
    You'd be surprised. Sometimes you add more than you think. Any downloads, recently edited documents, etc all will add to the total. Plus system files such as browser history are updated and backed up as well. If it has been a few days since your last backup, I wouldn't worry. If this is happening ALL the time and you know that you have been barely using your computer, you may have a problem that needs to be further looked into.

  • My Time Machine backups are significantly larger, and slower, over WiFi than Ethernet

    My regular hourly backups from my Time Capsule began acting up a month ago. They were abnormally large (25-100 MBs) and took a long time--once, six hours.
    I connected my Time Capsule to my MacBook Air through ethernet to repair the disk through Disk Utility, (I turned Airport off on the Air, but not the Time Capsule), and then to rebuild the Spotlight index for the Time Capsule.
    Backups over ethernet work just fine now. The backup will happen in two parts, of around 200 KB each, and take two or two and a half minutes. But when I turn Airport on the Air back on, reconnect to the WiFi network, unplug the ethernet cable, and immediately start a new backup over WiFi, the two parts balloon to around 20 MB each, and the backup takes hours.
    This is a backup over ethernet, which took 2 minutes, 21 seconds:

    I live in an apartment building so there are a number of WiFi networks around.
    Not to mention cordless phones, microwaves, etc., any of which can interfere. 
    On iStumbler, my network shows up twice--once on channel 149, with signal strength of 50-65% and noise of 15%--and again on channel 10, with signal strength of that wildly varies from 20% to 90% and noise of 20%. Other networks in the building are on channels 1, 2, 6, and 11. The graph of channel 149 is very smooth, while the graph of channel 10 is choppy.
    It's probably using 149, as those numbers are pretty good.   Press Alt/Option before clicking the Airport icon in your menubar to see which band it's using.
    Watch the band it's using while running a backup.  Try other channels in the area of 149.  Unfortunately, it's a bit of a "hit and miss" thing. 
    Why are there two networks? Is that part of the problem? My Time Capsule is located about three feet right and a foot below my desk, so I can't think of a reason why it wouldn't be 100% for both channels.
    It's a dual-band router.  As I understand it, OSX will pick the best signal.
    I really want to know I have a clean, safe, accessible back-up before I replace it though. Right now I don't trust the Time Capsule.
    Do at least your last backup via Ethernet.

  • Time Machine not using any more space?

    My Time Machine backups go back to Jan 4, and show the expected pattern of hourly, daily, and weekly folders each of which appears to be about 78 GB. The log looks fine.
    Time Machine Preferences indicates that it is backing up about 90 GB. On my 500 GB (nominal) USB2 backup drive the space in use has remained at about 101 GB for weeks, despite many Time Machine backups each day of about 1 GB each (big because of a big Microsoft Entourage message database that changes every time an email comes in).
    This makes no sense to me. The space in use should be increasing by at least 1 GB per day, and the free space should be decreasing by the same amount, but both stay essentially constant.
    Any explanation?

    The answer was OS updates that made Time Machine far more reliable.
    Beware though -- if an OS glitch causes your Mac to lose its date and time, as happened to me a few weeks ago, you need to turn off Time Machine promptly or it will re-save every file on your hard drive. It took a couple of full restarts after I got the date and time corrected before I could turn Time Machine back on and not have it report that it had to save hundreds of gigabytes of files.

  • Time Machine Backup Disk "Out of Space"

    When doing Time Machine Backups, my disk says that it is out of space and there's just no way this is possible. I have deleted all old backups, but it still says my disk only has ~14GB of space. What am I doing wrong? PLEASE HELP ME! Thank you.

    Hi K.wood,
    I had the same issue awhile ago and i couldn't explain it either. I ended up forgetting the time capsule storage drive and then re-adding it and it seemed to do the trick. Hope that helps, if not let me know.

  • Time machine is backing up more GB than I have in my HD

    iMac, OS 10.6.8
    I have a new 1TB HD that I want to use for Time Machine backups. I have 499.76 GB on my iMac HD but TM (which is still copying over to the external HD has put almost 8GB of stiff on it. What's up?

    Oh, I see. Nevermind.

  • How might I move my Time Machine Backups.backupdb file to a partition on a different drive to enable reformatting the drive it is on, so that might put it back in place later?

    I have an external drive I use as my Time Machine backup location.
    Recently, I started getting an error on it.  It tells me there is a problem, and to repair it with Disk Utility.  Disk Utility cannot verify the disk, and needs me to repair it, but it cannot repair it. It advises me to copy all of the important files from this disk to another location, and then reformat the drive.
    So, I have copied all of the files that were not part of the Backups.backupdb folder structure to a partition on another disk, and removed them from the defecting drive, leaving ~250GB of files in the Time Machine backups files.
    I cannot seem to get this to copy to a ~350GB folder on another drive, formatted Journaled, Extended as recommended.
    What do I do?

    A Time Machine backup is owned by TM.. this is standard kind of issue.. the very fact that you cannot copy it suggests it is corrupt.. or you cannot change permissions on the whole file.. let me assure you the way TM works.. what you have so far copied is completely useless.
    Have you run a verify of the backup??
    The fact that disk utility is not working means something is wrong.. it should be able to fix a drive..
    And the fact the drive is only 12-18months old is also not relevant.. the present state of the drive is too poor to be considered reliable.
    What type of drive is it.. ie USB2 USB3 and what brand??
    It is not just the disk that can go bad but the controller/power supply as well.. and some brands seem to have bad batches.. eg seagate USB drives I was seeing recently.
    I prefer drives where I buy a shell and put the drive into it.. so I can move the drive to another shell without breaking warranty (or the case).
    The actual command for terminal I always just look up when I want to do them.. I am getting old and I have no space left for command line stuff.. although it was all there in the past.
    eg today I hit. http://www.cnet.com/au/news/using-the-os-x-terminal-instead-of-the-finder-to-cop y-files/
    This includes the rsync command.. lets try this one..
    I can copy my downloads directory to a time capsule disk. I start with login as super user just to make sure I don't have permissions issues.. you should definitely do this. running rsync is great as it will give you info when it fails and it will do incremental if you run it again later. You construct the command by simply dragging the folder from finder into terminal and slightly modifying it as per the article above.. So my actual command as I am copying deliberately to a new folder on the TC.. You don't want files to land on the root.. even if it creates another folder.
    $ sudo su
    Password:
    sh-3.2# rsync -av /Users/Ray/Downloads/* /Volumes/DataTCgen3/downloads/

    I have 60GB or so in this folder and it is copying at about 20MB/s over ethernet.. so it is not super fast.. but there is probably some error checking going on at the same time.

  • Which disk did Time machine backup if running Mac OSX 10.6.8 on an external startup disk?

    The original hard drive on my 2007 iMac was pretty full, so I was using an external hard drive as the startup disk while I got around to replacing the original hard drive. I could still see the original hard drive and its contents and it still had a bootable copy of OSX 10.6.8 on it, but I was starting up from the external drive running OSX 10.6.8. I recently attached another external drive and backed up with Time Machine. Now the original internal hard drive has crashed. I can no longer see it to even try to repair it. My question is, was that internal hard drive backed up with the Time Machine backup, or was only the external startup disk backed up? If the internal one was backed up, how can I retore it's contents to another drive? - Thanks

    Sorry to hear.

  • Will my files i saved using time machine still exist if i delete from my computers hard drive?

    I recently had a problem with my computer. I bought an external hard drive and used time machine to back up my 15in mac book pro before sending in for repair.
    I have gotten my computer back and needed to delete files from the hard drive on the computer ( close to capacity). Was I safe to do so knowing that everything is saved on my external?
    My concern is that if I plug in the external hard drive it will now see those files have been deleted from my computer and delete from the external as well.

    Just wanted to add to this conversation - Time Machine will keep copies of your files for some time.  It is a backup system, after all.  Deleting the files from your main hard drive will not cause Time Machine to go and delete them from your backups.
    However, eventually, Time Machine is likely to run out of space on your hard drive, and it then does some cleaning up so it can continue working.  A file that is not on your hard drive will not exist on your Time Machine backup forever.  Eventually it will be deleted to make room for more recent backups.  I can't predict how long this will take, but if you have bought a 1TB or so drive for your Time Machine backups, I would suggest that you might be able to keep some months of backups online - after that, old files that you no longer have on your Macbook Pro will be cleaned away.
    So Glenn is spot on - if you want an archive copy of those files, you should make a separate backup - Time Machine does not keep your files forever!
    Hope that helps.

  • Time Machine Backups.backupdb folder more than one directory for the same machine

    Hi I am trouble shooting a Time Machine issue for somebody. They have multiple backup directories for the same machince in the Backups.backupdb folder. This causing the directory that is being used to have a restricted amount of space to use, therefore the backup timeline is only lasting for one month where oldest backups are being deleted. On top of this I notice that the options to delete individual backups or all of them is not available. I read that this can happen where there is duplication in backups.
    Any suggestions in how to remove backups that are redundant and select the correct one to keep appreciated. And...suggestions on why this may have happpened. One reason could be that when the Mac was originaly bought, two portable iomega drive were purchaed one to use at a main residence and the other at a country home. Each disk may have been used at different times for Time Machine.

    Start with Pondini's TM FAQs.

  • Can I consolidate Time Machine backup archives from more than one HDs?

    I have several HDs with Time Machine archives on them. One is 1TB, one is 500GB, and another is 250GB. I am out of space on all three and I am considering buying a 3TB HD. Can I consolidate all the existing archives? If so, how do I do that? If not, how can I search all three (or four if I buy the new drive) archives if the Time Machine preference only allow me to use one archive HD at a time?

    In Time Machine Preferences click on search another drive.
    Have a nice day.

  • Time Machine thinks I have more data than I have

    I have re-setup my time machine after it seemed to be having troubles after I installed a new internal hard drive. I formatted the drive and started from scratch.
    I setup the options to exclude folders I dont want to backup and it says that the estimated size of full backup is 890.81 GB, which should fit fine on my 1 TB time machine drive.
    But when it comes time to actually do the backup, it eventually gives me the error that there is not enough room on the drive and that I have 10 TB of data that I need to backup. How can it get that number when both drives on my system are 3 TB total?

    I did a repair and still had the same issue. Here is what Time Machine Buddy says:

  • Time Machine backup says no more room but there is one TB available?

    Time Machine suddenly tells me it cannot back up as "the backup is too large for the backup disk."  My backup hard drives are both 2TB capacity, and the data to be backed up is about 1.01TB.  I have indicated that Time Machine should delete old backups to allow new ones to be stored.

    Hi Joseph,
    A couple of things, please look over Pondini's Time Machine FAQs & Time Machine Troubleshooting. If you cannot find a solution there you may want to consider reposting in the Snow Leopard forum. TM is part of OS X and you will find a section for TM in the version of OS X you're running which appears to be Snow Leopard.

  • Time Machine Backup failed, not enough space...

    Have iMac, Yosimite OS 10.10, processor 3.1 GHz Intel Core i5, memory 12 GB 1333 MHz DDR3, internal HD - 1TB, Time machine id 1 TB external La Cie. I see that I have 260 GB left on Time Machine disk, on Time Machine window. Additional message, "Needs 266.46 GB for back up, thus "backup failed". What is my next step? Thank you very much indeed!
