making copy of 0 level dump via ufsdump

Hi
how do u make "copy" of o level dump taken via ufsdumo in solaris?
To elaborate, imagine you have taken a 0 level dump via the following command
ufsdump 0ulf /dev/rmt/1n /

and then again execute the same command to take a second 0 level dump

Now take an incremental dump
ufsdump 1ulf /dev/rmt/1n /

The problem is; if you try to restore the first dump, and then the incremental one, you would get an error "incremental volume too low".
This would essentially mean that in case your 2nd 0 level dump goes wrong, you can not restore the complete file system.(Thats what my understanding is"

Please let me know if there's any patch/solution/workaround for this.
Multiple copies of 0 level dumps are needed for off site storing.
Thx
Vishal
