External storages recovery (NAS and DAS)

Network-attached storage devices or NAS are media with a multiple disc array, connected to a PC either via the network switch or directly to a computer. Taking into account a limited number of hard drives available in a computer as well as insufficiency of disc space NAS systems have become much in demand today. Their implementation allows to increase disc space by additional hardware units. They are particularly beneficial if users download or copy films, videos, music, games which occupy large amount of disc space. Besides, NAS disc system can be represented with different high-performance RAID arrays that increase data access speed as well as provide means for data protection against loss if one or two discs crash.

Data access and recovery solutions for NAS and DAS devices

Although NAS devices are considered to be a quite reliable storage, poor access to information stored on these units occurs often enough to cause computer users troubles while working with data. As a rule, most NAS devices are formatted with specific file systems which are generally not identified by an operating system running on a computer. Hence, users cannot read files formatted with a such a system.

Since UFS Explorer supports the majority of most widely used file systems you can easily gain fast, direct access to data located on NAS devices. Furthermore, the software assures data reading both from hard disc drives as well as RAID 1 arrays.

Regarding other RAID levels used on NAS devices, apart from RAID 0, data access is possible only after a RAID array is virtually reconstructed with UFS Explorer. The software developed by our company supports major algorithms for the placement of segments among the discs in the arrays commonly applied on NAS, including RAID 5, RAID 1+0. Therefore, it helps to create a virtual RAID from its components using "healthy" discs that provide sufficient data redundancy.

Furthermore, users of direct attached storage boxes (DAS) can be offered with multiple data recovery options as well.

DAS similar to NAS is an external unit responsible for storing and managing data. But unlike NAS devices direct attached storage boxes are generally connected to a computer through USB port. Being low in cost and able to be organized as multiple high-performance RAID arrays they have won popularity among home computer users. The resulting fault-tolerant disc system prevents data loss in case of a single or double disc failure. In this event UFS Explorer software helps to make virtual reconstruction of RAID 1, RAID 5, RAID 0+1 and other RAID levels typically used on DAS boxes. By creating a virtual RAID the data stored on a failed array disc are recovered and therefore become available. However, the only stipulation for successful data recovery with UFS Explorer is information redundancy of a RAID array after disc crash.
