Hi,

     Recently I have renamed multiple folders containing a lot of pictures/video on my MacBook, folders containing more than 150+ GB worth of stuf. When I try backing up my Mac, however, Time Machine tries to back up those folders AGAIN, and I know that because of all the hard link usage and other methods of backing up, Time Machine will always re-backup folders that have been renamed.

 

My question is, how can I get Time Machine to recognize the renaming of those folders and not have to back up everything in them again? I would prefer not to chenge the folder names back to what they were before.

 

     Any help is appreciated. Thanks!


MacBook Pro, Mac OS X (10.7.5), 2.3 GHz Intel Core i5, 8 GB RAM

    Rrenaming makes it a new file to any backup program, as the full path name is the only tag the original and the backup share between one backup and the next. When you rename the file that breaks the association, and the backup utility sees the new name as a new file or folder.  Where a full path name is the file name and the names of ALL it parent directories. In the case of Time Machine the starting directory is the beginning of the mounted file system. Different backup utilities will use different starting points.

     

    IF you want an alternate name, consider keeping the original name then create a Mac OS X Alias with the new name or a Unix symbolic Link. These special files are just pointers and backup utilities know they are not the real file, so only the pointer information is copied, not the contents of the file.
