Hi,
I’m sorry to hear that you’re experiencing an error with DPM2022. Error code 100243 is not a common error code, and I couldn’t find any specific information about it. However, I found a Microsoft Support article that describes the issues fixed in Update Rollup 1 for Microsoft System Center Data Protection Manager 2022 .
The article also contains a note may related to our issue.
- Note: Existing Data Protection Manager to Microsoft Azure customers should upgrade to the latest agent (version 2.0.9249.0 or later). If the latest agent is not installed, online backups may fail, and no Data Protection Manager to Microsoft Azure operation will work.
If you’re still experiencing the error after installing the update, please feel free to contact us for further assistance.
I hope this helps!
