Overview
You can restore Groups data within your Microsoft 365 tenant - ensuring business-critical data is always available when you need it.
You can view all the available snapshots and restore data. You can restore an entire snapshot or only group settings. You can also restore groups’ data to the same location or to a new group.
📝 Note
If a Group Site is quarantined then the corresponding entire group is quarantined. You cannot perform a full restore on this quarantined group data.
You cannot restore or download the data if the associated group site is quarantined.
Order of Restore in Groups
Here's the logical order for restoring a Microsoft 365 group, including Planner and SharePoint data:
Group Metadata Restore: The process begins by restoring the group metadata. This essentially creates a new group with the same configuration as the original one before deletion.
Planner Restore: Once the group foundation is established, the system then restores the Planner data. This includes tasks, buckets, and comments, but not attachments.
Group Mailbox: After restoring Planner data, the system sequentially restores the Group Mailbox, starting with emails and followed by attachments.
SharePoint Restore: Finally, the system tackles SharePoint restoration. This ensures that all attachments associated with Planner tasks, which are stored in the corresponding SharePoint site, are recovered as well.
Restore considerations
Group Restoration Limitations:
Due to Microsoft API limitations, a Distribution group or Mail-enabled Security group will be restored as a new Microsoft 365 group. You cannot restore the owners of these groups. For more information, see Back up Groups data.
You can restore a deleted group on the Microsoft 365 portal as a new group only.
Restoring data to a new group without any existing owners may result in Druva adding an owner to ensure proper management and protection. If a group has only one owner, it is not possible to remove that owner, as every group must have at least one owner to maintain control over settings, members, and content.
Group owners added by Druva can inadvertently gain access to a non-subscribed group in the following scenarios:
Restore abruptly ends - The owner added by Druva will retain access indefinitely.
Global admin is changed - Any owner added by Druva who could not be removed during the restore will retain access indefinitely.
Group has no owner, or restore is tried without any owner - The owner added by Druva will retain access until a new owner is added to the group.
Geo-Location Limitations:
Restoring a group site associated with a Microsoft 365 Multi-Geo tenant will restore the site data to the same geo-location. Changing the geo-location during restore will still result in the site data being restored to the original geo-location.
Microsoft Planner Limitations:
Microsoft Planner restore may not recover the "completed by" information associated with tasks, requiring users to rely on alternative methods like change history or manual updates. This is due to a limitation in the Microsoft API.
If a SharePoint site has a sub-site named 'Documents,' granular restore with Planner is not possible. This is because 'Documents' is the default folder for storing attachments. For example, if the folder name is changed to 'New Folder' and there is a sub-site with the same name ('New Folder'), the restore process will fail.
If a Planner attachment is deleted or updated from the SharePoint site, but the associated Planner task or bucket remains unchanged, the Planner attachment will not be restored during a Planner restore operation.
Granular restoration of attachments in the form of links is not supported, regardless of whether they originate from the same site, a different site, or an external source.
Group Mailbox Restore Limitations

Restore considerations due to Groups naming policy
When a restore is initiated, a group is created. The Microsoft Groups API leverages the Microsoft 365 groups naming policy and the new group is created as per the naming policy.
For more information about the naming policy, see, Microsoft 365 groups naming policy in the Microsoft documentation.
Consider the following when you:
Restore to a new group
Restore a deleted group
The group will be created as per the group naming policy wherein if you are using:
Custom Blocked Words naming policy: The custom word you have blocked in the naming policy will be appended with a three-digit randomly generated number when the new group is created. So, the new group will be created with the name <blocked word><three digit number>. For example,
Word blocked in the naming policy: Sample
Original group name: Development Sample
Restored new group name: Development Sample123
For more information, see Custom block words in the Microsoft documentation.
Prefix-Suffix naming policy: The prefix or suffix you have defined in the naming policy will be appended to the new group. So, the new group will be created with the name <Prefix>Name of the team<Suffix>. For example,
Prefix string: Company Name | Suffix string: Cost Code
Original group name: Development Sample
Restored new group name: CompanyNameDevelopment SampleCostCode
📝 Note
Ensure that the restored group has no more than 256 characters, or the restore will fail.
