Hi!

Ok, without -a it works. Furthermore I mounted the md0 device with -t vnode 
instead of vfs.
I just loaded "aio" and it works with the "a"-option as well.

But I'm afraid that the backup of the whole file does not function

# /sbin/ufs_copy -a /mnt/fw/testfile /dev/ad0s1g
copying /mnt/fw/testfile to /dev/ad0s1g

This "copying" takes about one second and hence nothing is there.
That is not that bad, cause often one or a few files are needed and thus I 
have to mount the backup-file anyway.

Thanks for ufs_copy! I'll go on playing around with it.

Regards,

Oliver.
