NAS Recovery
Network Attached Systems (NAS) enable users to store
and share data over a local area network (LAN). With
NAS, additional storage capacity can be easily provided
to organizations of any size by simply attaching NAS
systems to an existing LAN.
Storage Area Network (SAN) which is a high–speed
dedicated network that connects data storage devices
with the respective data servers.
The amount of information stored on magnetic media
is doubling every year, and managing storage in general
purpose servers is getting more expensive and complex.
NAS server is preferred implementation for serving files,
because it is easier to implement and manage, and it
provides much better I/O performance over general–purpose
servers.
The data stored on NAS and SAN server systems in today's
computerized network environment is nothing but falling
short of making data storage more critical. Many businesses
solely depend on these servers to keep their businesses
running smoothly. When one of these servers fails, it
can lead to significant hourly financial loss, and in
extreme cases can even lead to complete business failure.
Most common causes of data loss in NAS and
SAN servers are:
- Logical Failure - configuration problems, accidental
deletions and human error.
- Failed Back Up - No back up available or your back
up has failed to restore.
- Physical Drive Failure - due to head crash or other
component damage.
- Inaccessibility - Security or network based failure
making the data unavailable for viewing.
- Natural Disasters - fire, water, flood, explosion,
tsunami or earth quake damage.
- Virus - client or outside host that has unintentionally
or intentionally caused a failure or overload on the
server making the data corrupt or inaccessible.
