I have searched around, but found no solution that would work for me.
Here is the setup I have.
I have a ReadyNAS DUO box that I use to store files and I add new files, change files, and delete files on a daily basis. This works fine for that. I have another readyNAS DUO I want to use as a mirror of that. I don't want the other drive to have to do a full backup everyday, I want to do an incremental backup. This is do-able with windows archive-bit. HOWEVER, it does not delete the files I have deleted on the original NAS box. I want to be able to have a backup of the drive that is a perfect mirror.
I have seen things about rsync, but don't really understand it and how I could use it.
I would really appreciate it if anyone could offer me some help in a solution. Thank you!
