Getting started with backing up Teams includes completing the Office 365 guided setup—which helps you perform some of the required setup tasks—adding the teams that you want to back up, and performing a test backup and restore.
Important: If possible, perform the getting started process in a test environment. After you perform a test backup and restore, you can move the system into production.
Verify that your environment meets the system requirements for Teams.
What to Do Next
For security reasons, consider changing the Office 365 global administrator account to a Teams administrator account.
If you want to automatically discover and back up all teams, add All Teams to the Teams app.
