Hello,
I have got two USB external hard drives each one 120 GB (hooked-up via a USB connection for backups.,,,,and I am looking to have same copy of my backup works on both external hard drives.
Let us call one external hard disk primary and the other secondary
Now normally I copy all my works (files, folders, rpograms, pictures,,,,etc) to the primary one, but after a while how can I let both hard drives have the same contents?
Of course I can copy the entire hard disk every few days from the primary to the secondary, but this is not practical.
Is there a program that can synchronize only new modified work from the primary USD HD to the secondary one ?
