Very good and useful information on comparing the different options. Good to know that BASIC option does not cost (No need buy Advanced Compression license).

Thanks a lot!

Care to share your scripts. I would like to do the same thing for our environment.

If you only store textual data in the database it is up to 1:8 (basic / high compression). For low compression it is apporx 1:3

Hi
Wanted to know what your experience is for the average compression ratio for rman compression.

Thank you for you help.

I would be interested to know how you tied the compression algorithms (LZO, BZIP & ZLIB) to the 11g RMAN compression settings (LOW/MED/HIGH)? I know the BASIC one is known. Care to share?

Cheers

Strange thing. Youre the first person to say that. I will take a look into the log files. Thanks!

Thank you for this useful post. But I had difficulty navigating through your site because I kept getting 502 bad gateway error. Just thought to let you know.
