Hi @Drew_C
thank you for your answer. It's related to NetApp Saas Backup and O365. The tool discover all our mail accounts, onedrive accounts...but doesn't discover our group sites of Sharepoint.
NetApp Support told me this sites are including in Office 365 Groups. currently we are making the backup currently, but I don't know how will work it because the copy (at the moment) is very small. Neither we know how will work the restore. We are wating for the copy to finish and we'll check this.
I will tell you.
