My situation is this:I have an external hard drive that holds all of my folders in my /home/ directory (/Documents, /Pictures blah blah all in the root of the external HDD) I have used rsync -r ./dir-on-computer/ ./dir-on-external-drive/ for the last couple months.>recently I've noticed that it takes a while when i use it and it seems to not just copy files I've changed but also ones I haven't. It's probably just my lack of patience, but I also have seen rsync -av be used as well for other people's backups (I know the whole archive and verbose tags, but just wondering what the difference is between -av and -r).So, overall I would like advice on two things: Better ways of using rsync, to make sure it is incremental(another problem) I would like to rsync the files in my Music directory without rsyncing the subdirectories in the Music directory (/Music/other-stuff/)I know I am being pretty lazy by asking this question instead of ploughing google for info, but I would appreciate it if you could give any informaton for my situation.Thanks
