# Data
## **Node Private Drive**
The Node Private Drive is a private staging area for your draft Nodes. It is hosted on our secure cloud infrastructure. In the staging area, you can build your research object and share with with your co-authors and collaborators privately.
The storage capacity is on a **per-user basis**. Publishing your Node clears your personal storage space.
## **Open state repository storage**
Once you click "Publish" and sign the transaction, your data is mirrored to the open state repository and progressively cleared from our cloud infrastructure. By publishing your Node, you clear storage space in your private staging area.
Multiple copies keep things safe: **your data is mirrored in 5 countries across 3 continents.**
The five copies are in an archival state in the form of [CAR files](https://ipld.io/specs/transport/car/carv2/). One additional "hot" copy is made accessible over the network at a high degree of availability, for a total of six copies. You can learn more about distributed archival storage [here](https://estuary.tech/).

**Contact us to store massive amounts of data efficiently and securely**
We are building our big data onboarding process. For datasets of >50TB, you can apply for sponsored storage via the [DeSci Foundation funding program](https://descifoundation.org/funding). We will help you onboard your data, link it to your node, and make it easily re-useable and creditable.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.desci.com/technical-background/open-state-repository/data.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
