A certain 8TB drive was full, so I got a new 12TB drive, mounted it in a trusty external hard drive dock, connected by esata
Ran This
robocopy H:\ L:\ /E /COPYALL /DCOPY:T /R:0 /W:0 /MT:12 /XJ /LOG:C:\robocopy_H_to_L_full.log
And walked away (without an explosion in the background)

Swapped the drives, and now I have
to play with, Matey.🏴☠️🏴☠️🏴☠️
EDIT:
Of course, if the AI Bubble hadn't made cheap storage and ECC DDR5 unobtanium, I'd be expanding a ZFS storage pool on a NAS by just adding a drive, but here we are.
