Cause

The NetWorker VMware Protection (NVP) vProxy solution does not support SQL (MSVMAPPAGENT) backups of SQL server 2022.

Resolution

See the NetWorker Compatibility Matrix: https://elabnavigator.dell.com/eln/modernHomeAutomatedTiles?page=NetWorker

The NETWORKER and ALL COMPONENTS, REPORTS, MODULES guides contain a table for NetWorker Module for Microsoft - SQL Server. This table includes the support information for both NMM and NVP vProxy MSVMAPPAGENT support. The table includes the following footnote:

58266: NVP App Consistent for SQL Server is not supported for SQL Server 2022 and Windows 2022. 

 

Request For Enhancement (RFE) NW-I-2427 was submitted requesting MSVMAPPAGENT support for Windows Server 2022 and SQL server 2022. Contact your Dell Site Account or Sales Team to track this RFE.

Workaround:

Install the NetWorker client and NetWorker Module for Microsoft (NMM) packages on the SQL Server 2022 machine. Both packages should be a minimum of 19.7.0.x. SQL backups can be obtained using the NMM client software.
