Copy all files and folders from USB drive to SATA drive..

[German]

Hi everyone.

I set up something like NAS for torrent files and installed debian on
it. Installed one 4TB internal drive. My files are on USB drive. I'd
like to copy all of them from my USB drive to internal drive. Are there
any commands to do it in one go? I also formatted internal drive to
ext4 filesystem. I hope I've done right thing. Please advice. Thanks
