Parameters and bottlenecks
Preservables vs keepables vs backup How far offsite, and how to get it there?
Concerns
Heavy-duty infrastructure – spinning disks use lots of power and create lots of heat
Successor to the STK5800 Preservation of metadata: how do you
preserve it if it won’t hold still? Staffing: appropriate level of monitoring
and checking
Future
Ongoing expansion Cloud storage? Trusted Digital Repository (TDR) Broader collaboration
