"De kosten die DANS rekent voor data in DataverseNL (excl. BTW):
- Opslag van data: € 1,68 GB/jaar.
- Back-up van data: € 1,14 GB/jaar.
Naast storage-kosten worden de kosten voor hardware en beheer doorberekend aan de partners (~4000 euro/jaar/partner).
Opslag van 100GB in DataverseNL, incl. backup, kost dus (1,68+1,14)*100 + 4000 = €4.282 per jaar.
(DANS maakt voor de opslag gebruik van de IT-dienstverlener Vancis.)"
(kosten voor) Duurzaamheid wordt gedelegeerd aan instellingen.
