The size of the timeshifting buffer is controlled by the values for Minimum and Filesize.When I change any of these two parameters, this seems not to be reflected in the time shifting info box, so I cannot see the (estimated) effect of my change.
The drive space values derive directly from the filesize and number of files, so I think that they are correct:I also think that the hdd space values shown in the lower area are irrelevant and false
