Costs
Storage "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.)"
