Data recovery for NAS

Network-attached storages (NAS) emerged in an environment with a large amount of information as a powerful solution for shared access to a storage. These systems found their principal implementation among corporate users where general centralized storage provided to several workstations was required. Being an advantageous solution for quite reliable data back-up and access from more than one computer, compact NAS devices have gained wide popularity among home users as well.

NAS systems function as file servers dedicated to providing the location for shared data storage and data access. They don't perform any operations of a typical server such as e-mail, authentication or file management. NAS device consists of a control board which provides network access to data and from one to several disks that can be organized as a RAID-system. This independent device with its own operating system doesn't require any external computer to manage its file system and restricts access to its disks. Despite high reliability, NAS-systems, like any technical devices, are exposed to failures and outages. Software malfunctions, control board failures or simply human errors may lead to the loss of crucial information. Normally, NAS devices don't provide access to the storage, except for NAS with iSCSI protocols. Thus, to recover data from a NAS, it's required to get disks out of the device and connect them to a PC for recovery. UFS Explorer is a comprehensive solution for the retrieval of the data lost from NAS. This software recognizes most presently applied file systems including those of NAS-systems. UFS Explorer RAID Recovery for recovery and reconstruction of RAID will be helpful when NAS disks are organized in a RAID-system.
