I usually carry along my portable HD when I am out and when I get home I need a software to sync my portable HD to an external HD, basically update anything new from my portable to my external HD without the need to do it manualy. Is there such a software? Thanks
There is. Either Carbon Copy Cloner or Super Duper. Those two are the most popular among Mac disk backup apps.
Yup those two can schedule backups, though I prefer SuperDuper. It's more complicated if you want the sync to run when you plug in the drive though and I haven't found anything that does that for cheap yet.
Can the super duper do one way sync? This is the scenario, I have a photo folder in both portable and external drive, when I plug in both drives I want everything on the photo folder of the portable drive transferred to the external drive, but if I delete something from the portable it wont delete from the external.
