I am looking for an application to transfer files between two or many servers. I have approximately 250 kinds of online/rpg game which it about 600GB total size, It’s going to be like this; Everytime I am updating the first server, the second server will sync from the first server’s partition that im working on it. At the same time works for the rest of servers using synchronization which won’t be needed to transfer all files and only replacing the missing files/new/different size or any file which doesn’t exist. Same chronicle not modified and so on. Could you please provide me a kind of software like that? In other word, the software also could be used as an auto update for any games or files. I found some of ftp sync software but it seems not smart app to use since it keep sync all the file on my ftp server even it doesn't need to be update. If u can add feature like new date/different date from source it will autosyn, so it doesnt need to check all file all the time which it gonna save more time for ftp sync to sync files needed. If u have this kind of software im myself need about 6 license for it, and i believe there more clients gonna buy from u especially cyber cafe owner like me because they need to use those app to autoupdate their game automaticly from their own ftp server or they can use mine to save more time for themself without they need to keep update one by one of their game.
