Here is my scenario.
I have to move 24TB of RAW film footage from one point to another.
The issue I have is I can babysit the copy process and the facility has problems with power outages.
Is there an app that copies files from one point to another and remembers what point it's at if there are interruptions?
I've used backup software such as Retrospect but something a little simpler would suffice.
I have used Beyond Compare for many years to keep hard drives and backups in sync for both Mac and Windows. I don't believe it will remember part of a file being copied, but at the file level it only copies what has changed so when you recover from a power failure it will compare files and dates and resume copying where it left off. Just point it to two folders and it will copy from one to the other or even keep them in bi-directional sync. It has the ability to use FTP (File Transfer Protocol) for remote servers so it might help your situation if the servers are remote and you can't mount the remote drive.
