If you are concerned about losing data, your first step is to enable archivelog mode. Your second step is to understand that an export is not a backup.

I understand that export is not a valid backup option but how can i get the data to new server and keep it realtime as the production server database?

Please guide.

Paraphrasing John Watson,
to achieve any of it, you first need the database in archivelog mode.
Then look into Oracle Dataguard.

Use a standby database or Data Guard.
Or use disk array replication like EMC SRDF.

First tell me,

1) What is Disaster recovery?
2) If no RMAN then, last option is IBM flash technology, but you will not recover point in time. There is some gap between them Shocked .

Very bad option as the last one, you can use a simple OS copy and you can recover point in time.
So if you can't do it with the product you mentioned, you should better just forget it.
