I'm on macOS High Sierra, and I'm trying to clone an older USB flash drive to a new one, using Disk Utility. 
Both drives work normally, with no known problems. Both are APFS and encrypted (if it matters).

However, the Disk Utility "restore" procedure fails.



The source USB flash drive is 256GB, APFS, encrypted, 31GB free.
The destination USB flash drive is 400GB, APFS, encrypted, 396GB free).

The Disk Utility "restore" procedure goes on for hours and hours, until finally at the end it craps out:
"The operation couldn't be completed. (OSStatus error -119930872.)"

Is there another way to accomplish what I'm trying to do? Maybe a Terminal command?

-Carl
