What is a Windows Storage Server?

Windows Storage Server is based on Windows Server operating system, and is available exclusively through Microsoft’s OEM partners with storage appliances. It is optimized for use with network-attached storage devices and gives you a platform to build storage appliances which are customized for your hardware. There are two different versions: as a workgroup and as a standard license. The two differ in the number of CPUs, the amount of RAM, the connected drives, and the simultaneous SMB connections.

How data is lost on Windows Storage Servers

Each Windows Storage Server data loss is unique, but there are certain scenarios which appear regularly:

  • Parallel operation of RAID, Windows Storage Spaces and virtual disks adds complexity to a  data recovery: e.g. A drive exchange (prompted by a failure) in the RAID leads to an incomplete rebuild causing the virtual drives contained in the storage pool of Windows Storage Spaces to be inaccessible.
  • Incorrect setup of the Windows Storage Server failover  without additional RAID level protection
  • Deduplication in conjunction with active virtual machines and disks, despite the warning from Microsoft.
  • Extensive exhaustion of all technological features, such as the combination and nesting of Windows Storage Spaces with HyperV and compressed fileservers contained therein.

All typical sources of error on NAS/SAN such as human error, overheating, power outages, defective drives (see NAS Data Recovery) can lead to data loss.

Tips for data loss in the Windows Storage Server system

  • In case of hardware damage, NEVER perform software solutions for RAID recovery
  • NEVER rebuild the original system
  • Check the quality of a backup before using it
  • NEVER restore a backup to the same location as the original data
