Ok I have some problems with this.
Caveat: I am not currently, nor have I in the past, been a software developer. Although I have had to play one in certain meetings.
My first problem is that this voter list was done in Access, that's pretty lame, should been some flavor of SQL.
Typically there would have been some other code that understands how to manipulate a stand alone Access database that goes in makes the changes, without that code you got nothing. And really how open is the source code for Access, it presents interfaces that allow one to manipulate the database but I would question how open the source is.
As far as getting her hands on the actual backup media...I don't know what the rules for discovery are for whatever (?) county the media came from but typically, at least with the private companies I've worked for, a court case is filed and requires discovery. The company issues a no-delete order then IT goes to active file systems and then to backup for requested data. The requested data is then written to other media (a USB drive or whatever) and then delivered.
The actual original backup media, not so much.
Edit: Stupid typos.
