No encryption, and --compression=zstd for both.

Command A:

dar --create - \
  --fs-root /tmp/test \
  --delta sig \
  | dar --sequential-read \
    --ref - \
    --isolate /tmp/destmeta \
    --compression=zstd \
    --delta sig

Command B:

dar --create /tmp/destmeta \
  --fs-root /tmp/test \
  --delta sig \
  --compression=zstd \
  --ref +

Thanks,
