Requirements
Please confirm you are running Veeam Backup for Microsoft 365 build 5.0.1.179 or 5.0.1.207 prior to installing this cumulative patch KB4135. You can check this under Help and Support > About in Veeam Backup for Microsoft 365 console. After upgrading, your build version will change to 5.0.1.225.
As a result of on-going R&D effort and in response to customer feedback, cumulative patch KB4135 provides a set of enhancements and bug fixes, the most significant of which are listed below:
Enhancements
- Optimized operations for faster execution of the (GET) /v5/Organizations REST API request.
- Optimized operations for faster execution of the Get-VBOEntityData PowerShell cmdlet.
- Optimized operations for faster execution of the following REST API requests in infrastructures where some of the remote proxies are offline:
o (GET) /v5/BackupRepositories/{backupRepoId}/backedupOrganizations
o (GET) /v5/BackupRepositories/{backupRepoId}/OrganizationData
o (GET) /v5/BackupRepositories/{backupRepoId}/UserData
o (GET) /v5/Organizations/{organizationId}/usedRepositories
o (GET) /v5/Reports/action for generating a Mailbox Protection report
- Ability to quickly get basic properties of backup proxies, including offline remote proxies, via REST API and PowerShell:
o using the “extendedView = false” with the (GET) /v5/Proxies or (GET) /v5/Proxies/{proxyId} requests
o using the “ExtendedView” parameter with the Get-VBOProxy cmdlet.
