We have a SQL Server (2012) job configured for Incremental, and backing up the transaction logs every 15 min. The Incremental SQL job completed this morning at 3:22am. We started getting these email alerts around 7am:
"Failed to save transaction log backup file for database PROD\interactive_security to repository: An unexpected network error occurred. Failed to flush file buffers. File: [\\nas01\veeam\SQL\SQL2015-03-25T030630.vlb]. Failed to backup file. File: [C:\ProgramData\Veeam\Backup\SqlLogBackup\{e32021d1-55e0-4f0a-84af-401fe55a02bf}.bak]. ItemSpec: [veeamfs:5:28aa2ab1-7a60-467f-8486-2426dbf1aeb3 (vm-68)\{e32021d1-55e0-4f0a-84af-401fe55a02bf}.bak@\\nas01\veeam\SQL\SQL2015-03-25T030630.vlbVBK:
Collected transaction logs do not match any existing full database backup: PROD\interactive_security; PROD\model; PROD\interactive; PROD\Main; PROD\DocManDB"
Other Veeam backup jobs are completing successfully. The only change we made to the job yesterday was from "LAN Target" to "WAN Target".
Any ideas?

Re: Failed to flush file buffers
Changing block size should not break anything regarding logs backup, so I recommend to continue with logs review with support.
