If I just move a 100Gb folder to another folder, is TM intellingent enough to get that it was a move?

Let me clarify: TM scans de internal disk and sees a 100Gb folder has been erased and a new 100Gb folder has appeared in another folder?

If this is the case then TM wastes 100Gb to 'remember' that data in the old position. Files are obviously the same, duplicated.

Sorry to ask this. I am trying to do the things right, this is a new iMac, I was using CCC in my old imac (TM was available but I couldn't backup on a network disk)


iMac, OS X Mountain Lion (10.8.2)

    TM does as you say 'waste'

     

    The deleted folder will eventually be removed (as needed) but not before.

     

    I used CCC in the past, still do and still don't like TM.

    Mmm, I see.  I am not sure what to use. I remember I suggested Bombich (2009) to create two backup sessions (system and data) because an unsolved problem I don't remember clearly.  CCC also 'waste' disk space in that way.

    Maybe to run periodically an app to detect and delete duplicates. I was looking for something like that: pay first and then you try. Mixed 1 and 5 stars reviews...

    What do you suggest?

    Thanks

    If you are trying not to waste Time Machine disk space, you can enter Time Machine, navigate to the old location of the folder and delete it (control - click, then delete all backups). Then you should only have one copy of the folder. Time Machine does take awhile to delete data and appears to be doing nothing, so you have to be patient.

    CCC, incremental Mode for 1 backup and something entirely different for the other.

    It would be a mess.  I said moving 100Gb folder but you know that real life is more complicated. A 300Mb video move here, another moved there, a folder containing 5Gb photos moved after edited. Many small things, day a day...

    I can't image using Reminder or writing Calendar 'erase duplicated Apr25 folder, mvi99.mov, etc'

    I'm not a developer but in century XXI I guess it is possible the OS logging your activity, moving data, for example, and also move the backup or something with sym links.

    Ah, you rememberd me that 2009 issue. /users incremental backup and simple backup for the System.  Is what you mean?

    I use CCC to create, and incrementally update a clone (2 actually), it is a full clone so it can substitute for my computer when I choose.

     

    I also backup to an offsite location in case of fire/theft etc.

    Is it possible to access files stored by TM from the Finder?

    1 backup is insufficient (for me)
