# Undo a run

> Take back an index run, a survey, a topics run or a draft.

Everything Clusters writes is shown as a dry run first, and logged before it is written. That log is what makes a run undoable.

## Steps

1. Run **Clusters: Undo a run…**, or select **Undo a run…** on the **Collections** tab under **Recent activity**.
2. Pick the run.

## What comes back

- The files the run wrote.
- The notes it made, changed or removed, unless you changed them since.
- The Graph view colour groups it set.

## What to know

- Runs are undone newest first, separately per kind: index runs and a survey's passages in one order; drafts, topics runs and a survey's **Write** each in their own. Undoing an index run never takes a draft with it.
- The last five runs of each kind on an index keep what undo needs. Older runs can't be undone.
- Undo does not refund what a run cost.
