Assuming I have two mounts, both on different NAS drives. If I 'cp' a file from (nas A) to (nas B) does the data hit the local hard drive at all? Or is it all handled in memory?
Reason for asking, I'm thinking of setting up a pi as a backup server, this will take a daily snapshot of my development stuff on one nas and store it on another. I have in the past wrecked an ssd in a couple of weeks with very disk intensive tasks, I don't want to be replacing system images every fortnight.
If the copy does 'stream' through the local drive I'd be better employing a small old pc with a physical disk.
Thanks folks.
