I came across this article:


which tested the performance of various Mac backup programs on metadata such as file creation dates, HFS+ extended attributes, BSD flags and ACL's, and concluded that the only one tested that performed OK on all of them was SuperDuper.

Does DropDMG (which wasn't tested for that article) preserve all of these correctly? I admit I'm not even sure why one needs all of them :-o but I want a program to do full backups with and don't want to be missing anything important.
