VSS writer 'SqlServerWriter' has failed ... after installation of SQL Server 2014
Have been running Acronis Backup 11.5/11.7 for more than 2 years on a Win7-64bit machine with no problems.
Have been successfully backing up an application that used SQL Server 2008.
After installing an updated version of the application that requires SQL Server 2014 backups are now failing (log file at end of message).
The failures revolve around VSS writer 'SqlServerWriter'. Using vssadmin list writers I can observe that
Writer name: 'SqlServerWriter' is in "State [8] Failed" and the Last error: "Non-retryable error".
If I restart the computer 'SqlServerWriter' is "Stable" with "No Error".
Launching the backup again results in failure, with 'SqlServerWriter' Failed with a "Non-retryable error".
Toggling Options>Default Backup Options>Volume Shadow Copy Servce" to "Use Volume Shadow Copy Service (VSS)" or "Do not use VSS" seems to have no effect.
Here's the log:

Any ideas? I really need this machine backed up.
Here you are Ekaterina:
A VSS writer has rejected an event with error 0x800423f4, The writer experienced a non-transient error. If the backup process is retried,
the error is likely to reoccur.
. Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.

Additional information:
The application requiring the upgrade to SqlServer 2014 is "Act!" by Swiftpage. I spoke with Swiftpage technical support and they suggested that I uninstall Act!, then Acronis, then SqlServer 2014, SqlServer 2008 and SqlServer 2005; all of which were on this machine.
I did so, then reinstalled Act! which installed SqlServer 2014. I then resinstalled Acronis.
After reinstalling everything I am still have the same issue. The above log entry was created just after the reinstallation of Acronis.
Thank you for additional information! I've found the following sources that provide some troublshooting advices:
I too have ACT 19 on a computer that was failing backup with the new 2018 Acronis. Using https://kb.acronis.com/content/59440 I switched the snapshot type from VSS to Acronis Snapshot. this was found under backup options -> Advanced -> Performance -> Sanpshot for Backup (dropdown). Seems to solved my issue.
Thank you for confirmation, Ron!
