Why is the space bigger? Don't you do incremental dumps?
Of course, but it will still take up much more space. If we do full dump
once a week
and incs each night there will be many duplicates of files changed early
after the full dump :-)
Do I correctly infer that you don't need a full backup as in "ability to
restore data from arbitrary points in time"?
Well, TSM only store one copy of a specific object, while if you do full
dumps + incs
there will be multiple copies.
For simply keeping a safety copy of your data, you should consider
OpenAFS+OSD (http://www.rzg.mpg.de/~hwr/Graz.pdf).
It interfaces with TSM HSM. ACLs are not archived, but there are other
ways to go about them.
The OSD way to get HSM is likely the way we will go in about one-two years
from now when we are changing our storage systems. We have had that
in mind when we now goes from NFS/SMB to OpenAFS.

The code is not in CVS yet, but until that's all done, we would
be pleased to already welcome more users of these features.
