Hi all,
I have a 100 DLT cartridges library with 35/70GB capacity each.
This is like 7TB approximately data on the library if the compression
utilization is like 100%( which is not the case).
In addition, there are like 37 cartridges with scratch status.
I would like to know how much
'select node_name,sum(file_size) as sum_file_size from contents group
by node_name'
'select node_name,sum(PHYSICAL_MB) as sum_phys_mb from occupancy group
by node_name'
and I got the following result
9,030,520 MB from the contents table
2,422,690 MB from the occupancy table

Hi Richard.
First, thanks for the quick answer :-),
Thus I need to asume from my select results, that the real size of the
backups in the library is taken from the occupancy table?
which is a reasonable number 2.5TB, and if its the only way to know what is the real
size of
my library?

Hi, Ofer - Yes, the Occupancy statistics reflect the real utilization
of your storage pools.

Ofer,
A couple of issues here.
First, and probably this is your answer, the 70GB capacity for DLT IV
cartridges on DLT7000 drives is an estimate assuming 2:1 compression. The
compression is done using a version of the Lempel-Ziv algorithm, like that
used by PKZIP and many other software
