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

    First, when you repair permissions are there a large number of files whose permissions required repair?

    Second, why do you have to frequently repair permissions?

    Third, what is reported in the console log regarding the TM backup?

    Fourth, check out 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 for additional information and help.

    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):

    I will check your suggestions.

    Once again, Thanks.

    I can't tell too much by the log as it doesn't seem to mention anything about the actual backup process. I do see frequent mention of CleanMyMacHelper, however. It would appear that TM is having some sort of problem with the sparsebundle that contains the backup, and the CleanMyMacHelperTool is often mentioned. If I were you I'd start by uninstalling the CleanMyMac software.

    Agreeing with Kappy that CleanMyMac looks suspicious.

    Are you doing anything else with it, besides permissions repair? (I wonder if some other process you can run with it is doing a "touch" of every file on your system.)

    Try doing a permissions repair via +Disk Utility+ (in your Applications/Utilities folder); see if the same thing happens. (And don't bother trying to repair permissions on your Time Machine drive -- that only works on OSX volumes.)

    New info:

    At first I didn't do anything. Three days ago I used CleanMyMac to remove a program and shortly after that, my Time Machine started to make a full backup of about 200G. No clue why.

    I looked in the log with Console and saw several messages from CleamMyMac. Then I stopped the backup process manually, rebooted the system and uninstalled CleanMyMac. The full backed didn't reappear and since then, Time Machine is nicely making incremental backups again. This saved me 200G of disk space.

    Conclusion: by now, I am pretty sure that CleanMyMac (or at least CleanMyMacHelper) was causing the problem.

    Will follow up.

    Yup, sure sounds like it.

    It must be doing a "touch" (that's actually a UNIX command) that changes the +last access+ and/or +last modified+ date of a file. I have no idea why it would do that, but that would cause exactly what you see.

    Thanks for the feedback; it will help someone else.

    By the way, just in case you don't know, you can use +Disk Utility+ (in your Applications/Utilities folder) to +*Repair Permissions+* without this problem.
