The issue: we are experiencing drive failure rates (a mix of media/SMART errors or complete failures) of one drive per month. Otherwise, the repository performs quite well with good throughput and low disk latency. The repository is running Windows 2016 and NTFS (I wasn't comfortable implementing ReFS which at the time was 2 years ago). Some of the checks do run simultaneously which can put a high IO load on the repository particularly when backups are running.īackups are run daily with forever incrementals (since we don't have the capacity to do synthetic fulls). ![]() run weekly patrol reads/scrubs (via MegaRAID) run monthly RAID consistency checks (via MegaRAID) To ensure the consistency of the backups, we do the following scheduled checks: The drives are configured in a RAID10 volume with 3 dedicated hot spares (using the builtin MegaRAID controller). ![]() We use Veeam B&R Enterprise 10 to backup our Vsphere VMs and physical servers to a Veeam storage repository - a Supermicro 6048R-E1CR60N with 43 Seagate Exos 12TB enterprise drives.
