Clone USB flash drive

[Yah]

Hi All,
I want to use another faster/smaller USB flash for Entware. Have HTTP/POP3/SMTP/FTP/MySQL servers running on my router. I got same size USB and already formatted it as EXT2. Looking for suggestion how to clone existing or copy everything to the new USB.
Thanks

use dd

dd if=/dev/sdX of=/dev/sdY bs=64K conv=noerror,sync status=progress

That appeared didn't work as my new USB flash some bytes smaller than current. I unmounted it and tried to DD in Linux Mint VM. Trying to backup and restore it. Any other better suggestions?
