Re: Oracle backup Problem.

Hi Thiru,

Thank you for the reply....
Presently we are now taking full backups of the database once a day.

And also i didn't understand exactly what archieved logs does. that is if the redo logs doesn't get filled will it still empty itself to the archieve logs and if so when?
actually i want the backup of redo logs every 2 hrs even if doesn't get filled.

Is that possible..Please help me.
Again thank you for your reply.

Sanjay.
