I have around 10tb of amassed video files some of which would be hard to replace. It is spread across various PCs and portable drives. Every few months I back up everything to a 12tb external HDD. When I do this, I delete everything from the back up HDD and then copy the new data. If there an efficient way of only saving changes rather than having to write it all to the disk each time? Probably less than 5% of the data changes between back ups. I don't want to go down the route a nas / raid array as I don't have the time / space / knowledge. Thanks.
