I am planning to buy a Toshiba Canvio 3.0 Portable USB Hard Drive of 1 TB to use as back up device for all the photographs I have.
I do not intend to use DropBox or similar cloud service.
However, I would like to know if I can use it as a diff or else I will have to copy the files all the time, over and over.
I have been looking for this info but I have not seen it or I have missed it
Do you have any experience with this kind of equipment ? Would you please share it with us all ?
Thank you
