but not all of them ...
One question : if using deduped and compressed pool, shall the "compress

Hi all,
TSM deduplication is effective combined with compression. Without compression,
I'm not sure that it worths what it costs (1:2,5 ratio or

I think most of you know Spectrum Protect just added in-line compression
to the container and cloud deduplicated pools in version 7.1.5:
