How database volume s and log gets backedup.

[PINNI, BALANAND (SBCSI)]

Hello all

I have a question pl excuse me if it is silly.

I back up my db through a script incremental specifying volumenames.

backup db devclass=acs_class2  volumenames=AA1201,AA1205


I see that i spite of specifyimg volume names each time it picks up scratch
volume
and does not backup on previous volume. why?


Thanks for any advice pl.
