given the "beginner" level in bash and working network connection, I'd recommend to:
- connect NAS and Laptop via LAN cables to your router or switch => about 100MB/s transfer speed expected
- connect external HDD to Laptop and copy using the same approach that already worked with small files
As a learning challenge: Any idea how to calculate expected duration ?
I would assume that the theoretical and fastest possible duration for the transfer would be 200GB=204800MB/100MB/s=2048s=~35min. However, I think a more realistic estimate would be five times longer since I'll probably reach transfer speeds around 20MB/s.
Is there a nice graphical view or log view of the transfer speeds in OMV?
