You're right to be worried - the first OAR will not be usable.  I have added some text to the error message to make that 
clear.

No, unfortunately it's more complicated than that.  The missing assets could be referenced anywhere (within serialized 
objects, asset metadata or even hardcoded within scripts).

In principle, you could untar the successfully saved OAR and grep all the files for the missing asset UUIDs.  That would 
highlight where they are being referenced.

But really, the missing asset problem should not be causing your initial OAR abort.  The asset service should return 
notification of missing assets as quickly as it returns actual assets.  Are you using a stock asset service?  Also, how 
many assets actually end up being saved - is it a very populated region?
