Tracking/recording changes inside a directory
I have no idea what to search for, or if there's even a way to do this, but is there a way to automatically record all the changes that occur inside a certain directory (my home directory in particular)? The record would then have to be able to be 'applied' to the original state of the directory to achieve the final state. You see, backing up files has become rather tedious, as I have to burn several DVDs every time I do my periodic backup - most of the data on them is identical to that of the previous backup, aside from some new/moved files and directories, a few modifications and perhaps a few deletions. Is there anyway I could record all of these little changes until they consume, say, 4480MB, and then burn them onto a DVD that could be applied to an older backup?
