Mine does the same, and it is not a drive problem, it is simply becuase
TSM has to scan all objects in the storagepool being backed up, to see if
they have been backed up or a copy should be made. For big storage pools
that can take quite some time, and especially if running at the same
time as expiration or other DB heavy activity.
