There are many ways to copy the shoot’s data, but unless you use software with a checksum you may not be copying everything every time.
I have bought and tried many different data transfer software apps and have recently found the best one yet, Hedge for Mac. Some of the others that I have bought and used are DoubleData, R3Data and Offload. While each has it good points they also fail in what I want them to do in some other ways.
The reasons why I think Hedge is the head of the pack is its speed. Basically it does what the others do but it does it faster . Its really only a little slower than using Finder, but does a checksum and writes transfer logs, meaning you have proof of the transfer being 100% correct. The speed of transfers and the ability to do simultaneous transfers to multiple locations is a huge plus!
