Summary0000768: Warning of failed VSS writer SqlServerWriter after 16.2 client upgrade.
DescriptionI have upgraded my Windows based clients from 15.2.2 to 16.2.4.
Backups of the (only) 2 servers that are hosting MSSQL always end in state "warning" with the following VSS error:

Warning: VSS Writer "SqlServerWriter" has invalid state. ERR=The writer vetoed the shadow copy creation process during the backup preparation state.

vssadmin list writers output:

Writer name: 'SqlServerWriter'
   Writer Id: {a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}
   Writer Instance Id: {06b0a0eb-8092-4850-a0de-b6b591f6d082}
   State: [7] Failed
   Last error: Non-retryable error

One of the servers is running MSSQL 2012 and the other MSSQL 2014.
Reverting the Bareos client back to 15.2.2 resolves the issue for both.

Steps To ReproduceInstall Bareos-fd 16.2.4 on Windows server 2012R2/2016 that is hosting an MSSQL 2012/2014 (Express) database instance.

Run a VSS enabled backup.
Additional InformationCurrently both servers are always running into this issue though one of the servers has ran a couple of successful backups after the Bareos client upgrade before this problem start occurring. The other server suffered from the issue since the Bareos client upgrade.

This situation probably does not make it always reproduce-able.
