Backup & Recovery for Microsoft 365

US Service Center offers a backup and recovery service for Exchange, OneDrive and Sharepoint. The service handles full Microsoft 365 Exchange, OneDrive and SharePoint backups so you can recover data long after it is cleaned or lost from Microsoft databases.

US Service Center 365 Backup relies on domain access to Microsoft 365. You have functionality to select only the mailboxes or accounts required for backup.

All backed up data is encrypted during the backup process and the encryption key is securely stored in the cloud.

Please note Microsoft 365 is the new name of Microsoft’s Office 365 service. The name for this was officially changed on April 21st 2020 and information on the change can be found here: https://docs.microsoft.com/en-us/deployoffice/name-change

Limitations

Exchange

Microsoft 365 protection has the current limitations:

  • You cannot restore calendar events that have not been accepted by the recipient
  • Only user accounts with Security Officer permissions can restore from deleted or unlicensed mailboxes
  • Only user accounts with Security Officer permissions can delete backup history for accounts
  • Due to a Microsoft API limitation, you may experience issues with the detection of some shared mailboxes.
  • We do not support hybrid Microsoft 365 installations for backup. On-premises mailboxes may be detected as connected to Microsoft 365 but we are unable to protect them as access is not given to the on-premises installation.
  • We do not currently support backup or restore of Public folders. This is due to the configuration of Microsoft data layers.
  • Protection for Archived mailboxes or a native Archive folder is not provided through backup.
  • You cannot backup from unlicensed mailboxes. Please confirm that the mailbox does not fall under one of these scenarios:
    1. The mailbox is present, but the license was removed. In this case, it will not be possible to add the mailbox to the backup.
    2. The mailbox and license were removed while the backup is in progress. In this case, the backup will not be able to complete and you will see the error “Unable to backup user without license” for such mailboxes.
    3. The mailbox is removed before the backup is started. In this case, the backup will run but skip this mailbox.

OneDrive

  • Only user accounts with Security Officer permissions can restore from deleted or unlicensed accounts
  • Only user accounts with Security Officer permissions can delete backup history for accounts
  • We do not currently support backup or restore of OneNote folders
  • Though OneDrive supports versioning, we only backup the latest version of files
  • You cannot backup from accounts that are not licensed or deleted
  • You cannot restore OneDrive items from the Trash folder (if the item was backed up before being moved to Trash, restore from the original location will be possible)

SharePoint

  • We do not backup SharePoint lists
  • We do not support backup of SharePoint pages, images and CSS files
  • We do not currently support backup or restore of OneNote folders
  • We cannot re-create a deleted site collection. If a site collection is deleted, it can be restored to a new location, which must be created manually. A site collection includes the site within SharePoint, as well as a site’s necessary structures (for instance, the site’s Document Library).
  • Due to a SharePoint Online limitation, role definitions can only be restored in a root site (or site collection)

Custom Document Library

If you are using a custom document library (DL) within SharePoint and the below applies, files may be inaccessible and will not be backup:

  1. Enforce unique values is set to ‘yes’
  2. Files are not checked in on SharePoint

To ensure all files are backed up when using a custom document library you must ensure:

  1. Enforce unique values is set to ‘no’
  2. Files have been checked in on SharePoint to recognize changes
