Estimating DB size with dedup

[BaR]

Hello,

We are planning to enable TSM side deduplication on an existing TSM server and after heading to IBM's documentation, I didn't see any reference to estimating the database size after activating TSM side deduplication on an existing TSM server.
Our current TSM server's database size is 250GB and I would like to know how can I estimate the growth of the database after enabling the deduplication.

Thanks,

Bar

It's hard to estimate, it's more based on space ingested than number of objects as each object is broken down in chunks.
