Only through a Global administrator service account with a proper license can Keepit obtain the access it needs to your data in order to back it up.
As part of the backup process and to ensure access, Keepit will make the Global admin:
- a member of all Office 365 Groups and Teams included in the backup
- a Site Collection Administrator of all SharePoint sites included in the backup
a Site Collection Administrator of users' OneDrives included in the backup in cases where a OneDrive has a folder with 5,000 or more files or an empty folder
Rest assured that adding the service account as a member or admin is completely harmless and does not in any way compromise the security of the data.
Note: It is possible to manually remove the service account from a group or from the list of Site Collection Administrators. However, this should only be done if you need to switch accounts or are stopping the backup altogether.
A proper license is necessary so that Keepit can make the Global Admin a member of all Office 365 Groups and Teams, and accordingly, back up this data. The following license plans give the Global administrator access to Microsoft Teams: Business Essentials; Business Premium; Enterprise E1, E3, or E5; Enterprise E4 (for anyone who purchased this plan prior to its retirement). For more information about license plans, see: How do I get access to Microsoft Teams?
A license is also necessary for Keepit to backup Public Folders.
