Hi all,

I want to hear what others are doing in regards of deduplication and large
files / database backups,

on a recent setup we are taking backups of a SAP Hana system to a direcotry
container,  I see great dedup stats when the system is doing log backups,
but I get no deduplication effects when we are doing full backups,
the database is roughly 250 GB in size,  and it looks like TSM sees the
object as one file.

ANR0951I Session 550996 for node xxxxx processed 1 files using inline
deduplication. 251,754,067,764 bytes were reduced by 0 bytes.  (SESSION:
550996)


I am not 100% sure how to handle this,   ....  are others using directory
containers at all?  are you using them for TDP Database backups ? any
thoughts ?
