Data recovery for NAS
Network-attached storages (NAS) emerged in an environment with large amount of information as a powerful solution for shared access to a storage. These systems became extremely popular among corporate users where general centralized storage provided for several workstations was required. Being an advantageous solution for 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 aimed at providing location for shared data storage and data access only. They don't conduct any operations, like typical for servers e-mailing, authentication or file management. NAS device consists of a control board providing network access to data and between several disks that can be organized as a RAID-system. This independent device with an own operating system doesn't require any external computer to manage its file system and limits access to its disks. Despite high reliability, NAS-systems are exposed to failures and outages. Software malfunctions, control board failures or simple human errors may result into loss of crucial information. Normally, NAS devices don't provide access to the storage, except for NAS using iSCSI protocols. Thus, to recover data from a NAS to getting disks out of the device and connecting them to a PC for recovery is required. UFS Explorer software, being the most comprehensive solution for retrieval of data lost in NAS, recognizes the latest applied file systems including those of NAS-systems. UFS Explorer RAID Recovery for recovery and RAID reconstruction is in the cases when NAS disks are organized in a RAID-system.
