Server – NAS – SAN – Data Recovery
A server is a computer used in a network and usually has more processing power, memory and storage than normal computers. Therefore, servers provide a service to other computers. These computers are known as the clients. The client is the computer that is requesting information from the server.
Understanding what a server is involves an understanding of what networks are. When computers are connected in some way, physically or wirelesslly, and sharing services or information, it is referred to as a computer network. In this network, there are two or more participants where at least one of them is acting as a server and the other is acting as the client.
The Function of a Server
The basic concept behind a client-server system is to economize bandwidth and performance by creating both a server that holds all of a system’s data and client software that accesses the data from the server. A computer, acting as the client, requests only what is immediately needed from the server. After the request has been made, the server full fills the requests. The system creates a layer of security as it allows a server to only full fill requests that a given client is authorized to make at any point in time.
NAS Data Recovery
Network-attached storage (NAS), is a file-level server connected to a network providing data access to a diverse group of computers or clients. NAS is specialized for serving files. This is done either by its hardware, software, or configuration. NAS systems are network appliances which contain one or more drives, often arranged like RAID. Because the data structure of NAS is that of RAID, recovering data from NAS is no easy task. Therefore, it is necessary that a data recovery specialist is contacted immediately.
Once NAS files or data has been lost, you will need to switch of the system and contact a data recovery specialist as soon as possible. Because the system is shut down, one prevents the data from being damaged any further and keep it from being overwritten.
SAN Data Recovery
Storage Area Networks (SAN), is commonly abbreviated as SAN. This is a storage device that users can access via a network. Although, SAN differs slightly from NAS. Because with NAS, users are permanently connected to the relevant storage media, whereas with SAN one must be connected before being able to access the data stored on it. However, just like with NAS, the data is stored on an array of drives. Therefore, the same data recovery process used to recovery data from RAID, Server or NAS, will be used to recover data from SAN.
Therefore, it is important that once SAN files or data has been lost, you contact a data recovery specialist immediately. Because the file structure is that of NAS and RAID, one must not try to restore the data. Rather contact an experienced data recovery specialist to avoid any further loss or damage.
