Release Notes for Veeam Backup for Microsoft 365 4b.

Please note that Veeam Backup for Microsoft 365 4с is now available and contains all the resolved issues from Veeam Backup for Microsoft 365 4b.

Please confirm you are running Veeam Backup for Microsoft 365 version 2.0 (builds 2.0.0.567, 2.0.0.594 and 2.0.0.814), version 3.0 (builds 3.0.0.422 — 3.0.0.480), version 4.0 (build 4.0.0.1345) or version 4a (build 4.0.0.1553) prior to installing version 4b (build 4.0.0.2516). You can check the product version under Help > About in the Veeam Backup for Microsoft 365 console. After upgrading, your build version will change to 4.0.0.2516. 

Version 4.0.0.2516 delivers compatibility support for Veeam Backup & Replication v10 and its applicable components and includes a set of bug fixes listed below.

What’s New 

 

• Support for Veeam Backup & Replication v10 compatibility.
• Support for Veeam Cloud Connect v10 compatibility. 

IMPORTANT NOTE:

• Veeam Backup for Microsoft 365 version 4.0.0.2516 is applicable to:
  • standalone installations of Veeam Backup for Microsoft 365
    • version 2.0 (builds 2.0.0.567, 2.0.0.594 and 2.0.0.814)
    • version 3.0 (builds 3.0.0.422 — 3.0.0.480)
    • version 4.0 (build 4.0.0.1345)
    • version 4a (build 4.0.0.1553; see KB3035 for more details)

• Version 4.0.0.2516 is NOT applicable to installations on top of
  • Veeam Backup & Replication 9.5 Update 4, 4a or 4b
  • Veeam Cloud Connect 9.5 Update 4, 4a or 4b
• Upgrading backup repositories from version 3.0 to 4b may take significant time to complete and the upgrade duration highly depends on the amount and type of backup data in a repository. According to the test results, it may take up to 8 hours in the setup with 1 TB of data in a backup repository. Plan for an appropriate maintenance window when your backup repository that is been upgraded is not available for use. Note that upgrading version 2.0 repositories to 4b requires a bigger maintenance window due to many underlying changes to backup repositories. The upgrade process requires an additional 15% of free space of the current 2.0 repository size and may take up to 17 hours per 1 TB of data in a backup repository. 

Resolved Issues

General

• Retention jobs do not fully purge the outdated service data, which causes product configuration database growth and impacts product upgrade duration. 

SharePoint Online and OneDrive for Business backup and restore 

• Adding users with empty Display Names to a backup job fails with the “Value cannot be null” error. 
• Backup of user’s OneDrive fails if the user name has been changed.  
• Backup job containing excluded SharePoint sites with changed URLs fails with the following warning: “Failed to get site collection: {url}. Access denied. You do not have permission to perform this action or access this resource.” 

Object storage repositories 

• Backing up public folders to a repository extended with object storage may fail with the following error: “This id is of the wrong type for this conversion operation (mailbox id vs. public folder id).”
• Adding OpenStack Swift (Stein) S3 Compatible object storage repository with the s3api middleware for S3 REST fails with the “Unable to create folder (name: {0})” error.
• Backup and retention jobs targeted at repositories extended with Amazon S3 object storage may fail with the “Specified argument was out of the range of valid values. Parameter name: count” error.
• If an Azure storage container that is in use with an object storage repository has been deleted, the corresponding backup repository is put into the Invalid state and the backup proxy disk usage is at 100%.
• A repository extended with Azure Blob Storage is still available for use (i.e. it’s not put to an Invalid state) when Azure storage account credentials become invalid. 
• After changing retention period for a repository extended with object storage, backup jobs targeted to this repository stop processing.
