1.4 Data Quantity and Rate of Growth

Printer-friendly version

If possible, a DMP should estimate how much data is expected to be generated and the rate at which it will likely grow. Such an approximation will also inform storage capacity and other related needs.

Some questions to consider, if data collection has already started, are the following:

  • Where and how are the data currently stored?
  • How long has data collection been occurring?
  • During this period, how much data has been collected or generated?
  • How much storage capacity is the collected data using?
  • How frequently have you needed to access the data?

If a specialized storage facility or capability will be required, it should be described in this section. This is more common for collections of non-digital resources such as physical samples, but may be helpful to address with other data types as well.
