SQL Plugin: BUFFERCOUNT = 4 Failed to perform backup

[Dmont]

We've recently started to use the Veeam SQL Plugin to backup our SQL databases. We've had a few issues that have been resolved by this forum plus Veeam support and hope you can help again.

One of our Veeam database backups is failing with the below error:
