I want to set up 2 external hard drives to automatically mirror my main external hard drive which contains all of my music and photos. External hard drive #2 would be kept at home and external hard drive #3 would be kept at work for safekeeping. I have no clue how to set this up or if it is even possible. I would like recommendations on who to set it up so the main external hard drive automatically backups any new files (songs/photos) to drive #2 all the time and then to drive #3 when I bring it home monthly and plug it in.
I know this sounds somewhat confusing because I am confusing myself but it is long overdue to backup my external hard drive. I would prefer not to have to pay for anything other then the extra hard drives. If I loose the family photos on the hard drive, my wife will look like this....
