Hi,
According to the IBM Blueprints, It looks I'm running "ultra tiny" TSM setup. I have only 1 TiB dir container pool. And I have to back up only two SAP HANA Instanaces: one 760 GiB and second around 360 GiB. Even having more than 900Gigs free, TSM refused to receive backup of the first one, claiming it "ran out of storage space". I had to define another pool, this time file based as an overflow. And it used this pool! But this is going to be a subject of further investigation since still, data stored into overflow file pool could easily fit into dirpool.
My question regarding capacity planing is: Imagine, having X free space in the dirpool. And Y size backup, which is slightly bigger than X, but deduplicates well. Does it mean I have to assure at least Y storage space in my pools, just to make sure it fits in case of no deduplication ? How much more space do I need?
Now, thinking of 6TiB HANA, means assuring at least 6+ TiBs of unused space! Kinda expensive...
And another question, perhaps wrong thread: how do I move data from overflow pool back to container pool?
