I have 2 8Tb My Book Thunderbolt Duo dual-drive storage devices, formatted RAID 0. One of them contains media files created by my video editing software. The other one is empty.
I would like to make an exact copy of these files on the other Thunderbolt device to use as a backup. That is, I want the files on drive A (4Tb) of the 1st device to go to drive A of the 2nd device, and the files on drive B (4Tb) of the 1st device to go to drive B of the 2nd device. The problem is that I can’t view the contents of the internal 4Tb drives A and B separately. If I simply drag all the files from the 1st Thunderbolt device to the 2nd, I assume they won’t automatically be copied to the corresponding 4Tb (A or B) drive at the destination. In addition, as I create new media files and delete some older ones, I will need to continue updating the 2nd device in the same way.
Is there a way to do this?
