We are currently running SQL Server 2005, and i need to archive data from databases in Production server to another server. From the information that i gathered, Which one of the following is the ideal way to do so
1) Using SQL Server Import/Export (At database level, i think this is easiest way)
2) Write some stored procedure using linked servers to move data from one server to other
3) Horizontal partitioning (I think this has to be done for each table in the database, i'm not familer with this)
Also we need only data that is three months older in our production database.
This appears to be a recurrent process to archive-and-purge data older than three month... if this is the case I would consider table partitioning by date range on the date that determines which data has to go to the archiving database then to be purged.
Once core tables are partitioned this way you just have to switch out the targetted partition then move the resulting table to the archiving database and switch the partition in. Fast, clean, reliable.
