The restore does start and it does create all of the files on the initialization of the backup. At about 20% into the restore it fails with the message I posted at the top of this post (0:0) from the backup from the NAS as well as the backup I create to local disk.

There are other databases on this SQL Server as well that I have backed up and moved to here so I know it isn't an environmental issue with this SQL Server.

Unfortunately this database is 800gig in size otherwise I would attempt to restore it to another SQL Server. I don't have that much free space on any other SQL Server.
