[SOLVED]: DPM Error (0x800423F4) or DPM (ID 3114) or DPM (ID 30111) VssError:The writer experienced a non-transient error. Or Backup Exec: 0xe000943f - Database s failed to freeze for backup. This can be caused if the database is in a state that does not support backup; such as offline, standby, or recovering.

I got my server backed up by DPM and Backup Exec, thus I had warnings from both backup solutions (error codes/IDs listed below).

At first check output of the command "VSSadmin List writers" 

if you'll see output like this: "Writer name: 'SqlServerWriter' State: [8] Failed Last error: Non-retryable error"

then just reboot your SQL server OS which is used for database in your SharePoint setup.

 

Symptoms :

DPM 2016 (Data Protection manager)

            Recovery point creation jobs for Microsoft Hyper-V xxxyyzz on xxxyyzz have been failing. The number of failed recovery point creation jobs = 1.

            If the data source protected has some dependent data sources (like a SharePoint Farm), then click on the Error Details to view the list of dependent data sources for which recovery point creation failed. (ID 3114)

           

             The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError:The writer experienced a non-transient error.  If the backup process is retried,

            the error is likely to reoccur.

            (0x800423F4))

           

             Please check that the Event Service, the VSS service and the shadow copy provider service is running, and check for errors associated with these services in the Application Event Log on the server xxyyzz. Please allow 10 minutes for VSS to repair itself and then retry the operation.
