Backup Exec: VSS Snapshot warning. File <path> is not present on the snapshot.
The i found this one here:
A product installer – possibly from a 3rd party app has registered that file as being required for a System State backup and not then removed the registration from the System State when the file was removed.
Either identify the vendor of the file and speak to them about a fix – or create a file with the same name in the same folder. Note it is unlikely that you will need the specific file for a restore (assuming your server does restart correctly currently)
So, to have a short break fix, just create a dummy file OR contact the vendor of the driver/program.

System State backup of a Windows 2008 server completes with an exception
Exact Error Message
Backup- System?State System?State
VSS Snapshot warning. File [PATH] [FILENAME] is not present on the snapshot.
Details:
System State backup of a Windows 2008 server may complete with the above mentioned exception if a driver file(s) was deleted/renamed. For example in the Figure 1, 04mmdat.sys is causing the exception.
Volume Shadow Copy Service (VSS) System Writer may list a file to be backed up even though the file is no longer present on the server. View the {GUID}-System_Writer.xml file located in the directory C:\Program Files\Symantec\Backup Exec\Logs to confirm if the writer lists the file present as an exception in the job log.
NOTE:
The exception can be safely ignored as it does not affect the functionality of the Backup set.
Workaround:
Follow the steps listed below:
1. Create a empty text file with the same name as the file mentioned in the exception
2. Place the document in the same location as in the exception
Resolution:

I’ve checked a few solutions (which were useless unfortunately), and you workaround turned to be both simple and a truly working solution.
Thanks
Many thanks, creating a dummy file worked for me too. This was even after removing the reference from the registry!
Well, for me it also seems working by using a dummy file placed to the mentioned location. BUT… If it’s a driver file (*.sys) put in the system32\drivers folder you should try to reboot your Win 2008 R2 server. You won’t succeed as Windows checks during boot phase if all drivers are consistent. A dummy file is no good idea!
