What is the best way to backup millions of small files in a very small time period? We have less than 5 hours to backup a file system which contains around 60 million files which are mostly small files. We have tried several solutions such as richcopy, 7z, rsync and all of them seems to have a hard time. We are looking for the most optimal way... We are open to putting the file in an archive first or transferring the file to another location via network or hard disk transfer thanks
