Dropsuite only uses one enterprise application for tenants, which is listed as Email Backup.
Once the user authenticates this app, we create four tenant apps for backup; they should be listed as Backup Application XXXX.
We create four applications for backup and restore purposes and to reduce throttling.
All these four applications have the same permissions and can be used to back up any type, such as emails, SharePoint, OneDrive, Contacts, Calendars, and Tasks, Groups and Teams, etc. If you use their Office365 account to log into Dropsuite as SSO, an additional enterprise application will be registered and listed as Email Backup Login.
