[ADSM-L] SAP Hana deduplication savings in directory stgpool

Hello all,

is anyone storing SAP HANA backups (using Data Protection for ERP) in
directory storage pools?
What are deduplication savings in your environment?

In our environment we see only 40% savings (35%-50%), comparing to
predicted dedup savings 1:9 (this ratio is currently valid for backups of
TDP4ERP Oracle, MS SQL, Oracle, ...).
This completely messes up the initial capacity planning :(
