Time Machine makes several huge backups a day

Hi,
I backup my Macbook Pro wirelessly with Time Machine to my Time Capsule.
This has been working great for about a year now. However since a week or so it keeps making these huge backups several times a day.
And by huge I mean 50GB+. I have tried D4 on the troubleshooting page but it did not work.
Any help would be greatly apreciated!
Specs:
- Macbook Pro 15" 2,53GHz Intel Core 2 Duo 4GB 1067 MHz DDR3
- Running Mac OS X Snow Leopard 10.6.8
- Time Capsule 802.11n

@Pondini: Well once I completed the steps and Time Machine was fully configured again, it went right back to the 59GB backup it kept doing before.
Are we taking about the same #D4 (in Time Machine - Troubleshooting)?
It has a number of common causes of extra-large backups, and links to #A2, which has a couple of apps that will show you just what's getting backed-up, so you can take corrective action.

  • Time machine makes a full backup every time

    I had a 1tb external drive that I was using for Time Machine backups. Fine. No problem. But it got filled up.
    I bought a new external drive - 1Tb. Iwas surprised that within a couple of wweeks, it was filled up.
    I bought a new 2Tb drive.
    Now as I observe what it's doing, it appears ot meaking a FULL BACKUP of my entire hard drive over and over again. I though it was only supposed to do incremental backups? This is nuts! At this rate my 2Tb drive will be filled up in no time. And becasue it's continually backing up many Gb of data it makes the machine run slowly. It is driviing me crazy!!! How do I stop this behaviour? Why is it making a full backup every time? I can't see any preferences to change this. Help!

    Thanks but I think maybe I didn't explain the problem clearly
    My understanding is that Time Machine backs up only the fiels that have changed each time it does a backup. Thi sis how it USED to work. So each hourly backup would take a few minutes, usually, and a 1TB drive lasted well over a year.
    Now it seems to be making a FULL backup of the COMPLETE internal drive EVERY HOUR! So it is currently backing up 135Gb of data and my Time Machine drive is almost half full,, even though I only installed it two days ago!
    When it gets to the point where it needs to start deleting old backups, I would get a new drive and start afresh, saving the old one for reference. I can't buuy a new backup drive every week!
    How do I get it to behave like it used to?

  • Time machine makes new complete backup sometimes

    Anyone knows why Time Machine sometimes makes a complete backup (even if no files have changed)? I'm backing up to a Time Capsule via wifi.

    See:
    See User Tips for 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.

  • Time Machine makes full backup after permission repair.

    I am struggling with this a couple of months but now I am sure. Each time I do a permission repair of my hard drive, Time Machine makes a full backup of roughly 200G. In this way my Time Machine disk can be full rather quickly. I seem not to be able to prevent this. Anybody having the same issue? Or, even better, having a solution? Thanks, Pierre

    Thanks for your reaction.
    No, only 10-20.
    I do permission repair once every 4-6 weeks more or less as a kind of maintenance. No idea why but it happens to be like this.
    This is in the log (and somewhere here the trouble occurred):

  • HT3275 Have OS 10.7.5. Computer off three days and now message comes that Time Machine could not complete backup because the "/volumes/PH's timecapsulPro.sparsebundle" is already in use. Whats that about?

    Have OS 10.7.5. Computer off three days and now message comes that Time Machine could not complete backup because the "/volumes/PH's timecapsulPro.sparsebundle" is already in use. Whats that about?

    Two Solutions for "sparse bundle already in use" Error
    Simple solution (from Bob Timmons):
    1. Make sure that no other Macs are backing up the Time Capsule at the time
    2. Pull the power cord from the back of the Time Capsule
    3. Count to ten
    4. Plug the power cord back into the back of the Time Capsule
    If Simple doesn't work:
    The Backup disk image ... sparsebundle ... is already in use.

  • Does Time Machine make bootable backups?

    I used a beautiful backup program called Backup Simplicity in Tiger that made a bootable Exact duplicate of my HD into my external drive. That's really I want to do.
    This morning I tried Time Machine for the first time. It only put a backup folder on my external drive. That's not what I want to do.
    So here's my question, if I totally erase my external drive will Time Machine make a bootable duplicate of my HD on my external drive also?
    Also, is there a way to schedule Time Machine for backups manually?

    No, TimeMachine doesn't create a bootable backup, nor can it be controlled manually. The purpose of TimeMachine is to work behind the scenes backing up changed files. Later, when you realize something is amiss, you can 'go back in time' and fix the problem. Admittedly, I'm a little shaky on the details of just how flexible the retrieval system is since I've not yet played with that feature yet. But as I understand it, if you installed a new program and your computer suddenly started going nuts, you'll be able to use TimeMachine to restore your computer to the point before you installed that program. Or, if you realize you improperly edited a file, you'll be able to retrieve the file prior to that editing session.
    Apple's team realized three things: 1) most of us don't take the time to perform backups even though we know we should be doing it. 2) most of us don't really understand how to develop a good backup strategy. 3) computers today are so powerful that most of the time the CPU isn't working hard at all and those extra cycles might as well be put to use doing something useful. Hence, TimeMachine's design.
    As you noticed, TimeMachine makes a folder and does its incremental backups inside. Since I have an external drive that is much larger than my boot/data drive, I'll continue to clone my boot drive to this external once a week, just as I've been doing. If disaster strikes and I need to use the computer right now, I can do so and at worst my data will be one week out of date. (I should then be able to use TimeMachine to retrieve the missing data but the important thing is that I'm up and running again as soon as I've rebooted.) Later (or if I have the time right away) I'll use TimeMachine to restore/replace my boot drive.

  • Time Machine deleted my first backup to make space for a new one, is there anyway to recover it?!?!

    So I had all my stuff backed up to December 23 on an external hard drive with Time Machine, then I deleted it all so that the next automatic backup didn't have any of these older files. Today Time Machine deleted my original backup to make space for a new one and so I lost Decemer 23, now I am screwed..HELP?? I accidently let it delete or something, I don't really know, I know this was just a series of mistakes and now I'm desparate ):

    Have a look at this article http://support.apple.com/kb/HT1427 and section "backup drive fills up".
    It's a normal behavior that Time Machine is deleting oldest backups when drive is filling up.

  • How to make Time Machine only back up once per day?

    I really really don't need time machine to back up EVERY HOUR. It's overkill for me and with the level of computing I am forcing my computer to do most of the day its VERY irritating. Is there anyway to change the settings so it only backs up once every night?

    Yeah, we tried using TimeMachineEditor on a friend's laptop. There will be 2 laptops backing up, and we wanted them both to backup overnight at different times when there would be no interruptions (for user or computer). It seemed to work OK (have to check w/ them), but how do you verify when backups were actually done?
    I have a couple related question to this, though, that may also be helpful for folks:
    - I'm guessing Time Machine cannot do a backup when the computer is asleep, correct? If a Time Machine backup starts while the computer is 'awake', will it keep the computer from sleeping so it can finish?
    - If I set a schedule in the Energy Saver preferences to 'Wake Up' the computer at midnight (before scheduled backup), and 'Sleep' later on (say 4am), does this override the other preferences set for sleep in Energy Saver? (ie - if it's set to sleep after 30min., will the computer wake up at midnight only to go back to sleep 30min. later, or will it stay 'awake' until 4am?)
    - Do you need to uncheck 'Put the hard drive to sleep when possible'?

    Time machine makes whirring noise 24 hours a day. Orange light often flashes. Does not appear to be overheating. Can you help?

    First: Are you wearing/regularly checking your radiation badge?
    Second: What does the little Time Machine icon (in the menubar) say when you click on it?  Alternatively, what does Time Machine Preferences (in System Preferences) tell you is going on?

  • In Time Machine "Unable to complete backup. An error occurred while completing the backup folder

    Time machine fails to complete backup

    I've been getting the Unable to Complete Backup error message for several days.  Last good back up was 11-22-13 at 11:13PM.  I am running an iMac with OS-X 10.7.5.
    I did the above steps in Console and got a huge string of lines; I tried to edit all repeitious ones that were the same, but still ended up with a lot of lines that seemed to develop more different processes over a few days.  Sorry to put all this stuff in here, but I don't honestly know what to make of all of this code language.
    Thanks for any help you can provide.

  • Time Machine cannot mount remote backup disk (ReadyNAS NV+)

    Hello,
    I own a ReadyNAS NV+ which I use as an external backup. It has a "Time Machine" backup daemon, so the iMac see's it over network. I used it for a couple of months without issues.
    A couple of days ago I had to change the physical location of ReadyNAS. Now there are 2 switches between my iMac and the readyNAS.
    Since I changed the physical position of the ReadyNAS I try to backup using time machine but it's not possible. Time machine hangs up when trying to up at "Making Backup Disk Available". Using the terminal I can clearly see that AFP has issues mounting the disk:
    afp_4pcsta0oyhi62C4wJd3Bx6yh-1.2e00000b on /Volumes/ReadyNAS (afpfs, nobrowse)
    angel:log root# dmesg
    6a800!
    jnl: disk3s2: journal_open: Error replaying the journal!

    Finally Time Machine exists with error "Backup disk cannot be accessed. error 109".
    Can someone give me a hint or two on how to solve this issue?
    regards

    Not a NAS-specific issue.  The OS is trying to read a block of the sparse disk image, and the read is failing.  Basically, the sparse bundle is damaged.  You'll need to rename it and then try backing up again to a clean sparse bundle.
    That said, make sure you're running a version of the ReadyNAS firmware that actually supports Time Machine.  There are several AFP commands that were added for Time Machine that *must* be supported for correct operation, and older AFP implementations did not implement them.  The reconnect errors suggest to me that maybe the firmware you are running doesn't support the Reconnect UAM, in which case it probably also doesn't support the replay cache, etc.  If that's the case, then things probably won't work correctly without a firmware update even after you fix the corrupted sparse bundle.
    Edit: actually, on further searching, it might be a NAS-specific issue.  Certain buggy network switches do not properly support jumbo frames in mixed networks, which can cause read errors similar to what you are seeing when working with AFP.  (This might have been your post on the other board.)  In the Network prefs pane, choose Ethernet, click "Advanced", click the Ethernet tab, change Configure to Manually, and set the MTU to Standard (1500).

  • Time machine Deleted old computer backups

    Hey,
    I have been using a mac pro for about a year and a half now and as all computers get it has become slow and full of garbage. So i used my time machine back up and successfully backed up all my files. I put in the OS disk and wiped the computer clean and reinstalled the OS. I plugged the time machine back up in and began to copy over only the files that i wanted. A few days later I had not yet copied over all of the files that I needed, i was prompted me to set up this computer with a time machine back up. I began the process thinking that it would create the backups in a new file on the drive or append it to the current list of back up images. It stopped half way though saying there was not enough free disk space. on the 1 TB HD there was only 5 GB remaining. So I just canceled it and was going to finish copying over all of the files i wanted and they delete the old backups. However when I went to get my old backup files, they had all been deleted.
    I was using this hard drive to store other media files as well as time machine backups. taking the HD into the local computer shop i was informed that that is a terrible thing to do and perhaps the reason that my backups have been lost. the tech said there was nothing to be done but reformat the drive and start again. I am hoping this is not the case. the drive still says there is only 5GB of free space however I can only fine 300GB of files on the drive. so i believe that the files are still there. Does anyone know a solution to this issue. There are many valuable things on this hard drive that i would hate to loose.
    I have tried holding the option key and clicking on the icon to view other backups, but my original backups are not there.
    Thanks in advance.

    Before I make any reply, note that you are responding to a topic that has been inactive for more than two years, on a system two versions out of date. In the future, you would do better to start your own topic in an appropriate forum, specifying what system you're running and what hardware you're running it on, among other things.
    this exact thing happened to me as well and I must say that I find it totally unacceptable...
    Well, without more information, it's impossible to say what might have happened or how you can recover. You may find some answers on Pondini's excellent site:
    http://pondini.org
    However, it's important to understand that this may or may not have anything to do with Time Machine. Perhaps your backup drive is dying, perhaps its directory structure became badly corrupt, perhaps one of any number of other things could have happened. Because there is no such thing as storage that is completely stable, it's important to keep more than one backup, as noted previously on this topic.
    Carbon Copy Cloner seems like a much better solution at this time.
    Carbon Copy Cloner is an excellent solution. Is it better? No. It is simply different, and that makes it better in some aspects and worse in others than Time Machine. The best backup strategy will involve two different backup programs. I frequently recommend using both Time Machine and CCC. I use TM with a Time Capsule for one backup, which has certain advantages over CCC. I use CCC for a couple other backups, one of which is in a safe deposit box at all times, and that has some advantages over TM. Using both, with multiple backups, means that I'm extremely unlikely to lose much data, if any at all... unless a meteor hits and destroys both my home and my bank, in which case I've got bigger problems!
    Anyway, with regard to recovery, take a look at Pondini's site. If that doesn't help, or you need assistance with something, start your own topic in the appropriate forum for your system and provide additional details that may help us better assist you.

  • HT3275 My Time Machine deletes ALL previous backups

    Every so often, Time Machine deletes ALL previous backups and starts over from scratch. It has done this several times in the last year.  I have not changed any hardware or the name of the computer. Why is this happening?  Makes me very concerned that I now have NO backups while it chugs away rebuilding a 210 GB backup. 
    Just got an error message:
    Time Machine couldn’t complete the backup. Time machine could not delete the backup disk image "/Volumes/Joe's iMac.purgeable"
    HELP!

    Hi Joe,
    Have you Repaired both drives first, then Repaired Permissions on both?
    Have you looked through Pondini's extensive TM help site?
    http://Pondini.org/TM/FAQ.html
    http://pondini.org/TM/Troubleshooting.html
    Can't imagine something not being covered there.
