# Understanding collections

:::callout{intent="warning"}
Pod-based indexes are legacy. Customers who signed up for a Standard or Enterprise plan on or after August 18, 2025 cannot create them. [Create a serverless index](/guides/index-data-create-an-index) instead. Serverless indexes use on-demand read capacity by default, or [dedicated read nodes](/guides/index-data-dedicated-read-nodes-overview) for sustained high query rates and workloads of millions of records or more.
:::

A collection is a static copy of a pod-based index that only consumes storage. It's a non-queryable representation of a set of records. You can [create a collection](/guides/using-pods-back-up-a-pod-based-index) of a pod-based index, and you can [create a new pod-based index from a collection](/guides/manage-data-restore-an-index). This allows you to restore the index with the same or different configurations.

Once a collection is created, it can't be moved to a different project.

## Use cases

Creating a collection is useful when performing tasks like the following:

- Protecting an index from manual or system failures.
- Temporarily shutting down an index.
- Copying the data from one index into a different index.
- Making a backup of your index.
- Experimenting with different index configurations.

## Performance

Collections operations perform differently, depending on the pod type of the index:

- Creating a `p1` or `s1` index from a collection takes approximately 10 minutes.
- Creating a `p2` index from a collection can take several hours when the number of vectors is on the order of 1,000,000.

## Limitations

Collection limitations are as follows:

- You can only perform operations on collections in the current Pinecone project.
