...a reflection of files on the filled tape expiring over time, which
reclamation will combine with other data to fill a new tape. Surrogate
reclamation tends to be quite slow compared to direct reclamation, where it may
not be able to keep up with the need for additional offsite tapes for new data,
the result being a considerable demand for the scratch tapes you have in the
library, which could account for your issue of running low on scratch tapes.
The only other suggestion that may apply is to verify the devclass Format being
used, that it uses compression so as to get the most onto the tapes.
