Every deployment produces a set of files, including the pages, functions, and assets Vercel serves. Deployment Storage keeps those files available so you can inspect previous deployments and roll back when needed.

**Instantly roll back to previous deployments in seconds**

If a production deploy ships a bug or a change you want to reverse, rolling back restores the previous version in seconds. Open your project, click [Instant Rollback](/content/docs/instant-rollback/index.html) on the Production Deployment tile, then choose an earlier production deployment. Vercel immediately repoints your domains to that deployment, with no rebuild required.

**Deployment Storage pricing**

- Deployment Storage is billed at $0.10 per GB per month
- Hobby teams include up to 10 GB

Existing teams continue with their current pricing, with no change to their bill at this time.

**Control how much Deployment Storage you keep:**

- Edit your [Deployment Retention Policy](/content/docs/deployment-retention/index.html) to set how long Pre-Production, Production, Canceled, and Errored deployments stay available. Shorter retention means less storage, but you can't roll back to a deleted deployment
- The Usage page shows Deployment Storage and Functions Storage by project
- Keep future deployments smaller by trimming your output directory, moving large files to Vercel Blob, and reducing Function bundle size
