To restore to a production environment, you must first change its type to sandbox.

Administration mode

You can set a sandbox, production, or trial (subscription-based) environment in administration mode so that only users with System Administrator or System Customizer security roles are able to sign in to that environment.

Administration mode is useful when you want to make operational changes and not have regular users affect your work, and not have your work affect end users (non-admins).

You can optionally disable background operations such as all asynchronous operations including Dataverse workflows and email server-side synchronization.

System backups

System backups occur continuously and aren’t counted towards capacity.

If you use Microsoft Power Platform to create production environments that have a database and Dynamics 365 applications enabled, you can benefit from the system backups that are automatically performed for those environments. The system backups are stored for up to 28 days.

For environments that don’t have Dynamics 365 applications enabled, the default backup retention period is only seven days. However, for managed environments, admins can use PowerShell to change the setting and extend the backup retention period. The available options are 7, 14, 21, and 28 days.

All environments, except Trial environments are backed up.

Manual backups

Automated system backups are great, but you should make your own backups before making significant customizations or applying a version update.

About manual backups:

• A backup is created for you when Microsoft updates your environment.
• You can back up production and sandbox environments.
• You can back up developer environments.
• You can’t back up the default environment.
• Sandbox backups are retained for up to seven days.
• Developer backups are retained for up to seven days.
• Manual backups for production environments that are created with Dataverse and Dynamics 365 applications enabled are retained up to 28 days.
