The SBS 2011 (Exchange is at SP1) Windows 2008 R2 suddenly stopped making backups with error
Backup unsuccessful. A Volume Shadow Copy Service operation failed. Unknown error (0x800423f4).
When manually starting the backup from SBS console, the backup will fail after 52 seconds.
Hardware setup

System State backup fails

ERROR - Volume Shadow Copy Service operation error (0x800423f4)
The writer experienced a non-transient error. If the backup process is retried,
the error is likely to reoccur.
I could not read .etl files
The wbadmin command output also points to log files that should be available at C:\Windows\Logs\WindowsServerBackup\, however there are no .log files there (only .etl files).
