Actually, you can with the "-p / --pause" option. Also, as per the man-page, if you forget this, the process will simply inform you the target location is full and you can move slices away to a different location: " If the destination filesystem is too small to contain all the slices of the backup, the -p option (pausing before starting new slices) might be of interest. Else, in the case the filesystem is full, dar will suspend the operation, asking for the user to make free space, then continue its operation. To make free space, the only thing you cannot do is to touch the slice being written. " The pause-option will actually stop between slices and you can umount the target location and mount a different disk there. This option has been around for a while. -- Joost
