Hello, I got somewhat curious how gnutar's listed-incremental is supposed to work.
AFAICS, amanda keeps for every backup gnutar's scratchfile and its index file (basically the output of 'tar -t'). I can see how amanda can determine which files/directories were added/changed since last N-1 backup (this are the files/dirs in the incremental index). But how does amanda know which files/dirs were _removed_ before the incremental backup was done? Neither the index files nor the scratchfiles seem to be of much use to determine this information. What am I missing here?
