Which file system improves accessibility and reliability by storing data across multiple servers?

The choice of a distributed file system is appropriate because it enhances accessibility and reliability through the distribution of data across multiple servers. This architecture allows data to be stored in different locations, which not only improves the availability of the data (since it is not reliant on a single point of failure) but also increases the performance by enabling parallel access to data.

In a distributed file system, multiple servers can work together, so if one server goes down or becomes unavailable, the data can still be accessed from other locations, thereby ensuring continuous operation. This setup is particularly beneficial for handling large volumes of data and is often used in cloud computing and enterprise-level applications where scalability and fault tolerance are crucial.

The other types of file systems do not provide the same level of accessibility and reliability. For example, centralized file systems store all data on a single server which creates a single point of failure, while local file systems are meant for individual machines without the added layer of redundancy or scalability. Hybrid file systems may combine elements of both, but they do not inherently guarantee the same level of accessibility and reliability as a pure distributed file system does.
