Requirements

Please confirm you are running Veeam Backup for Microsoft 365 build 5.0.3.1033 or higher prior to installing this cumulative patch KB4278. You can check this under Help and Support > About in Veeam Backup for Microsoft 365 console. After upgrading, your build version will change to 5.0.3.1063.

As a result of ongoing R&D effort and in response to customer feedback, cumulative patch KB4278 provides a set of enhancements and bug fixes, the most significant of which are listed below:

What's New

  • In RESTful APIs, we reduced the number of requests to Microsoft Graph API to speed up the execution of the (GET) v6/organizations/{siteId}/sites request.
  • Reduced time to retry the “Item has been changed during…” errors (status code 412) which you can receive during the main backup job run.

Resolved Issues

General

  • Retention job may mistakenly remove SharePoint and OneDrive backup data (including Teams channel files) from an object storage repository. The issue applies to repositories configured with the snapshot-based retention and backup data migrated from a local Jet-based repository to object storage using the Move-VBOEntityData cmdlet.
  • Under certain conditions, in object storage repositories, the retention job may fail with the “JetError -1605, JET_errKeyDuplicate” error.

Backup

  • Incremental SharePoint backup may fail with “The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator” error.
  • Under certain conditions, backup of SharePoint sites created in non-Latin languages may fail with the “Length of parameter ResourceName exceeds specified max for the column” error.

Restore

  • Restore of SharePoint items’ attachments from an object storage repository fails with “Error: Recursive read lock acquisitions not allowed in this mode.”

RESTful API

  • The sizeBytes parameter in the (GET) /v5/RestoreSessions/{restoreSessionId}/Organization/OneDrives/{oneDriveId}/Documents/{documentId} response body returns negative values if the item size is larger than 2 GB.
