I use Mountain Lion 10.8.4. Recently my Time Machine started to behave wierdly: when backup is going, expected backup size is always by few GB larger than completed part. So that at one point of time it's 70 of 74 GB's done, after that it's 71 of 75 and so on until backup volume runs out of space.

 

Reported backup size for my system (inside time machine configuration, with some directories excluded), is about 75 GB's. When the backup is failing, it gets as high as 200+ GBs.

 

For me it looks like some kind of hard link directory loop what "generates" data over and over.

 

I've already tried emptying the TM volume. Also the Disk Utility doesn't find any problem with volume (which is backupped) data.

 

What's the best course of action in this kind of problem solving?

 

Some logs:

    As I see that an "error 19" is involved, that the error log includes references to the network destination, and that the .sparsebundle file is involved, it may be the same issue discussed and resolved here:

     

    https://discussions.apple.com/thread/4158843?start=0&tstart=0

     

    Have you tried the solution offered in that thread?

    The backup volume is full. How many snapshots do you see when you enter Time Machine?

    I've tried "tmutil setdestination" command, no visible differencies :-( Sorry.

     

    Still something like

    (75 of 83, 78 of 86 etc)

    I've cleared the backup volume soon after I figured out the problem exists. So I have like 300+ GB of empty space which is not enough for ever-increasing backup amount :-(

    How big is your startup volume and how big is your Time Machine volume? Have you excluded anything in Time Machine to make it fit? It sounds like your Time Machine drive is just too small. Get an external drive three times the size of your startup volume and create a new backup.

    If you're trying to back up more than 300 GB (or even slightly less than that) to a 300 GB volume, it's not going to work.

    Backup volume reports 367 of 367 Gbs free after cleanup.

    data1.png

    After exclusion, my ssd under backup reports 75.75 Gb expected backup size. (75.75 * 120% < 367, right?)

    data2.png

    In any case of exclusion, the source SSD is only 256 Gb in size.

    data3.png

    I've tried to clean TimeMachine volume (yet again) and start all over. For half an hour it went normally (target size kept as 50 Gb, so the whole deal looked as finishable). After half an hour, projected backup size went on and on (51 of 54, 52 of 55 etc with no end, ending up with no free space available).

     

    It still looks like some kind of hard link loop in the FS, but I see no way to find it.

    Triple-click anywhere in the line below on this page to select it:

    diskutil list | open -f -a TextEdit

      

    Copy the selected text to the Clipboard (command-C).

     

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

    Paste into the Terminal window (command-V).

     

    A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.

     

    If any personal information appears in the output, anonymize before posting, but don’t remove the context.

    Please read this whole message before doing anything.

    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.

     

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
       
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Test while in safe mode. Same problem?

     

    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
