Write dd image to NFS (AWS EFS)

Question

I have a disk image (from dd). Is it possible to save it to NFS (AWS EFS).

Of course I can mount it (loop) but it is over 1.5TB of small files and cp or rsync works very slowly.

I also tried by aws file sync, but unfortunately I get an error: Input/output error.

Hosts:
HOST A: Mounted image dd + nfs server
HOST B: Host with AWS file sync

Answer 1

Yes you can. Use EFS File Sync for the best performance:
