Andrew Pruski troubleshoots a problem:
I was adding databases to an availability group (SQL Server 2017 CU20 instance) the other day and one database failed to automatically seed to the secondary.
When I looked in the SQL Server error log I saw this error message: –
BackupIoRequest::ReportIoError: write failure on backup device ‘{GUID}’. Operating system error 995(The I/O operation has been aborted because of either a thread exit or an application request.).
Read on to see how Andrew solved the problem.
