Database Software

Hi All,


We have a 30TB database for which we need to design a backup strategy.( Oracle 11gR1 SE, 2 Node RAC with ASM)

Client needs a DR site for the database and from the DR site we will be running tape backup.

The main constraint we are facing here are size of DB which will grow till 50 TB in future and another is we are running in Oracle standard edition.

Taking a full RMAN backup to a SAN box will take around 1 week for us for a DB size of 30TB.

Options for us:

1. Create a manual standby and apply archive logs( We cant use Dataguard as we are in SE edition)
2. Storage level replication ( Using HP Continous access)
3. Use thrid party tools such as Shareplex,Golden gate, DBVisit etc

Which one will be the best option here with respect to cost and time or do we have any other option better than this.

We cant upgrade to Oracle EE edition as of now since we need to meet the project deadline for Client. We are migrating legacy data to production now and this will be interrupted if we go for a upgrade.

Thanks in advance.

Arun
