Restore Behavior in Azure Active Directory

Restoring object relationships

When restoring an object that owns relationships such as a role (which owns role members), the relationships from the selected backup will be appended to the existing object.

For example, select an Azure AD role to restore from backup.

During backup, the role members were Sally, Michael, and Phil.
Currently, in Azure AD, the same role has Sally, Phil, Steve, and Cindy as the members.
After restoring the role from backup, the members will be Sally, Michael, Phil, Steve, and Cindy. None of the roles existing members in Azure AD are removed, while the members from role in the backup are appended to them.
