Backup and Recovery
Backup and Recovery In this part we want to know, what is Backup and Recovery? Backup refers to storing information in external memory to protect information from accidents and loss. Recovery refers to returning data from a saved copy to the original location or to an alternate location where information has been lost or damaged. To store information, we use a separate system or media such as virtual hard drives, data storage servers or cloud storage space to protect them against the possibility of data damage. Why do we need backups? Why do we need backups? By making a backup…
Network Attached Storage (NAS)
Network Attached Storage (NAS) NAS is a type of data storage that is designed to be accessed and shared over a network. It is a standalone device that can be connected to a network, typically through Ethernet, and provides centralized storage for multiple clients or devices on the same network. NAS devices are often used in homes, small offices, and businesses to store and share files, media, and other data among multiple users or devices. They offer several advantages over other storage solutions, including: Centralized storage: All data can be stored in a specific location, which can be easily accessed and…
Storage Area Network (SAN)
Storage Area Network (SAN) A Storage Area Network (SAN) is a specialized network that provides high-speed block-level access to data storage. Unlike Network Attached Storage (NAS), which provides file-level access to data, SANs are designed to provide direct access to individual storage devices, such as hard drives, solid-state drives, or tape drives. A SAN typically consists of a dedicated network of servers, storage devices, and switches that are optimized for high-speed data transfer. The servers in a SAN are often connected to the storage devices via Fibre Channel, a high-speed networking technology that allows for low-latency and high-bandwidth data transfer.…
