The restore of our database to new server hareware failed with a page error.

Message
SQL Server detected a logical consistency-based I/O error: 
incorrect pageid (expected 49:8125916; actual 49:29097436).
It occurred during a read of page (49:8125916) in database ID 7 at
offset 0x00000f7fbb8000 in file x:\Databases\Data07\DataWarehouse_OperationalData_15.ndf'.
Additional messages in the SQL Server error log or system event
log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately.
Complete a full database consistency check (DBCC CHECKDB). 
This error can be caused by many factors; 
for more information, see SQL Server Books Online.

A DBCC CheckDB will take us about a week on this 70 TB database and 6 years old server.
Is there any chance that it is my backup that is corrupt?
Or that the new server is at fault?
Or is it the production database on the old server that is the problem?
