# Large

Environments of this size are the most difficult to describe because they introduce a large number of variables. Treat this more as a proof of concept which probably needs some tailoring to suit your specific needs.

* Network: minimum 10Gb/s
* Number of sites: 1+
* Number of **Storware Backup & Recovery** installations: 2 server and (min.) + 2 nodes
* min. 8 vCPU and 16 GB RAM
* Number of backup threads: 10 per node
* Backup window: 12 hours
* Data to back up: 25 TB+
* staging space: your\_largest\_VM \* backup threads - per node
* Number of parallel backup threads: depending on the number of virtual machines (maximum 10 per node)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.storware.eu/backup-and-recovery-7.4/deployment/sizing/large-environment.md?ask=<question>&goal=<endgoal>
```

`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.
