I have a friend that lives on the other side of the world. They have a hard drive full of important files. Their hard drive is almost completely full, but they don't have money to get a new hard drive for more room. And they're worried about something bad happening to this hard drive. I have over 6TB of free space on my server's hard drives. So I figured I might as well put that to good use and help out my friend.
But my friend says he has 300gb of files on this hard drive. He doesn't have the room on his hard drive to copy the data into one big zip or rar file. So the directories and files will be have to be sent in their present state to my server.
My friend probably doesn't have very good internet, and 300gb is a lot of data to transfer no matter what. It's going to take a long time. I'm very patient. I don't care if the data moves at a trickle and takes a couple of weeks. But there's another problem. The power grid where he lives is very unreliable. He is only able to keep his computer running continuously for 6-7 hours. If he runs the computer longer than that, he risks the dirty power breaking it.
So any large transfer like this is going to be interrupted, and it'll have to start back up where it left off.
What kind of transfer can Open Media Vault facilitate to move his directories onto my server with frequent interruptions?
