copy tablespace in one database

Hello  

I plan to copy data from all tables to the new tables in new tablespace every night. Why? Old tablespaces will be purged every night and I have to have old date

I think that I have two options:

First

I have to copy tablespace to the new with new name plus date e.g. tablespace "name" to the new name_date.

Second:

Create tables in new tablespace "as select" but what can I do with indexes?  

I do not know if first options is possible.  

Maybe you have any idea to help me.

Rgds.

Wojtek
