KM0201, if you wanted a backup you are better of this way. depending on how often you rsync this gives you a little time to restore deleted/overwritten files.
pierre, i would like someone to confirm this befor i post the bug report. could you do that?
i would think -S has the higher priority aswell, because the command has only this one purpose. on the other hand -B is probably the newer command? i cant test it also because i have my system partition on the same drive as my data actually. having a vm running there aswell makes the drive not to go to sleep. (made me think of fight club now, lol)
