Backing up files
Hi,
I would like to know the best software to use to back up files.
I have a large music collection which currently sits on my Mac Mini, I would like to set up a weekly back up that checks what files are new and only copies the new files. these files will be then copied to a 3TB USB3 hard drive.
If anyones knows of free software than will do this please let me know
Cheers
Mac mini, OS X Mavericks (10.9.1), 2.6 GHz i7
