Parameters and bottlenecks

Preservables vs keepables vs backup How far offsite, and how to get it there?

Page 10: Digital Preservation Infrastructure in the University of Alberta Libraries

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
