I just copied in the Finder (drag and drop) into a folder, added something to 
the folder name (so it didn't clash with a later backup) and then put it into 
the MobileSync/Backup directory where they go.  Nothing special, all seems 
normal in iTunes etc.

Yes reset to new, no luck, and I don't use iCloud backups.

Backups not encrypted and I have spent days trying to "patch the backup" so 
that it would ignore OmniGraffle.  There are a number of plists in the backup 
but also a binary database (manifest.mbdb).  I even did a small bit of binary 
patching of that database but no luck.

A different error - it detects the files are missing etc and won't restore.  I 
believe the file list is in that binary database and I don't have a tool to 
edit it properly.  I tried taking Omnigraffle out of the plists but again it 
detects this (since still in mbdb) and won't proceed with restore.

I have restored ok before but this iPad seems to have gotten into a state that 
can't be restored.  I noted one of the Omnigraffle document plist files was 
empty when it shouldn't have been, so I put something from another plist into 
it but still no success.  

The problem is that currently iTunes doesn't allow you to restore specific 
applications (or the flip-side to exclude particular applications when you 
restore).  It is an all or nothing restore process and currently it seems a 
little too fragile for my situation.  

Perhaps in a future version of iTunes we will be able to restore just a 
particular application (or not) from a backup - that would solve my problem.  
Alternatively, if I could just tell iTunes to ignore this error and keep 
restoring, I think I would be good.  

My hope it that Apple may have tools (or some way) to do this.  It was beyond 
the capability of the Apple Store Genius and his boss (they suggested hardware 
failure but I doub that).  I am going to ring AppleCare.

Thanks again.

Cheers,
Ashley.
