 # Automatic deletions from deployment history
 
-When you deploy resources to Azure, the deployment details are recorded in the deployment history at the scope where the deployment occurs. Each scope — whether it's a resource group, subscription, or management group—can store up to **800 deployments** in its history. Once this limit is reached, Azure **automatically deletes the oldest deployments** to make space for new ones. This automatic cleanup process has been in effect since **August 6, 2020**.

 ## How to opt out of automatic deletions
 
-You can opt out of automatic deletions from the history. **Use this option only when you want to manage the deployment history yourself.** The limit of 800 deployments in the history is still enforced. If you exceed 800 deployments, you'll receive an error and your deployment will fail.

 To disable automatic deletions at the tenant or the management group scope, open a support ticket. For the instructions, see [Request support](./overview.md#get-support).
 
 To disable automatic deletions at the subscription scope, register the `Microsoft.Resources/DisableDeploymentGrooming` feature flag. When you register the feature flag, you opt out of automatic deletions for the entire Azure subscription. You can't opt out for only a particular resource group. To reenable automatic deletions, unregister the feature flag.
