Dear All,

I am trying to use the following command to backup the spfile with retention period 7 days:

>>>>
RMAN> backup spfile keep until time 'sysdate+7' tag='D_SP_TEST';
<<<<

However, RMAN creates 4 backup sets instead of one. Does anyone has any idea why? If I don't use the "keep" clause, I don't have this problem.

Any suggestions are welcome.

Thanks and Regards,

-- Chris
