Hello, in the last word from Gostev, he explained major data corruption warning for the enterprises who have already jumped the much improved Windows Server 2016 deduplication for production use. Last week, Veeam has started to receive multiple reports on corruptions of backup files hosted on Windows Server 2016 NTFS volumes with Data Deduplication feature enabled. Luckily, the issue was easy to spot due to the system event log event (rarely the case by the way, as most storage-level corruptions go undetected – which is why it is extremely important to have storage-level corruption guard enabled in the advanced backup job settings at least when you are trying out new things). Yesterday, Microsoft released the known issue (KB3216755) to fix for Data Deduplication in Windows Server 2016 in the most recent Windows update package!
