We have centralized database (SQL server 2000) where data gets consolidated from distributed databases (databases on remote branches - SQL Server 2008). Two of the remote branches are failed as the database servers are crashed and we have back up of a couple of days back (due to some issues current back up is corrupt) which we have restored and to bring the those databases on current state, we are applying the data from data transfer files sent by those databases to the centralized database. This process is taking time as the data transfer files are quite huge in numbers.
All the database servers are proper in terms of hardware requirements for normal operations but these applying of files on databases is taking time and with current rate we have estimated around 36 hours. Our customer is not agreeing with that much down time for those branches as those are one of the critical branches for their business operations. Is there any way we can expedite the data reading and applying process of files for those databases?
