Long story but Server Packed up... Drive Faulty

We have a dbcopy based backup on another server from night before

We also have a Drive Mirror of the Server about 2 weeks ago put aside for upgrade but other pressures meant we did nothing !

Ok, so I boot up with the 2week old mirror & it works - everything back in time 2 years
If I copy the GW Backup to this server what happens to the 6 new accounts created over the last 2 weeks ??
