I was wondering if someone can tell me if there is an advantage and/or disadvantages for creating many tablespaces for the same table (backup recovery, performance, administration tasks,..etc).
I have schema who got One huge table (40 GB). This contains 3 years worth of info downloaded every monthy, so far I have 20 tablespaces. The DBA was in charge, was creating a tablespace for the new month and then load that month's data in it. I am leaning towards changing that process and structure, but I thought I'd seek an expert advice. Thanks in advance...

We can store the data of same table in different tablespace based on range .
Look for table partioning .
Have data files on different disk for each tablespace

Having multiple tablespaces gives you a better control in terms of phyiscal placement of objects.It doesnt mean they are phyiscally separated ,but gives you the option and control to tune them better.
Other benefits might be easy reclaim of space (say when dropping partition), transporting specific objects, high availability during tablespace recovery etc.
But again too many tablespaces(how many depends) might also add to admin efforts.
