Can an iPhone be updated with a backup file that is older than the newest available?

Question

My husband has lost all of his iPhone information when he cleaned it off to start over, then saved a new backup that wiped out all his old info.  Is there any way to go back to a previous backup to retrieve all his lost contact information?

Yeah, each column in the CSV needs to have a descriptive header. Here's what I used to quickly test that example script I posted above:
loginDetails.csv:
Server,User,Date
Server1,user1,8/12/2014 16:18
Server1,user2,3/21/2014 12:33
Server1,Admin,6/13/2013 15:34
Server2,user3,8/14/2014 7:34
Server2,Admin,11/14/2013 7:30
Server2,user4,8/12/2013 8:03
Server3,user5,8/14/2014 7:34
Server3,user1,7/14/2014 7:30
Server3,user3,6/12/2014 8:03
Server4,user5,8/14/2013 7:34
Server4,user2,6/12/2013 7:30
Server4,user3,2/12/2013 8:03
Output of example from above:
Under 3 Months - Server1 user1 8/12/2014 16:18
Over 3 Months - Server1 user2 3/21/2014 12:33
Over 3 Months - Server1 Admin 6/13/2013 15:34
Under 3 Months - Server2 user3 8/14/2014 7:34
Over 3 Months - Server2 Admin 11/14/2013 7:30
Over 3 Months - Server2 user4 8/12/2013 8:03
Under 3 Months - Server3 user5 8/14/2014 7:34
Under 3 Months - Server3 user1 7/14/2014 7:30
Under 3 Months - Server3 user3 6/12/2014 8:03
Over 3 Months - Server4 user5 8/14/2013 7:34
Over 3 Months - Server4 user2 6/12/2013 7:30
Over 3 Months - Server4 user3 2/12/2013 8:03
