Continuous Data Protection (CDP) is a data protection method that continuously captures or tracks data modifications and stores changes independently of the primary data. A CDP appliance works by intercepting all writes to the production volume. It splits each write operation into two copies: one copy is written to the production volume, and the other is sent to a separate storage location where the changes are logged. This enables recovery to any point in time and helps ensure data integrity.

Data backup is the process of copying data to a secondary location to protect it from accidental deletion, application crashes, data corruption, and disasters. Regular backups ensure that data can be restored to a previous state in case of any data loss events.

The image illustrates a typical network connectivity setup where clients are connected to servers via an Ethernet switch, and the servers are connected to storage systems through an iSCSI target and an FC switch. This setup is representative of compute to storage connectivity, where the servers (compute) access storage resources.

The Cisco MDS-9132T switch model supports NVMe over Fibre Channel (FC) in a 32Gb/s SAN fabric. NVMe (Non-Volatile Memory Express) is a protocol designed for SSDs to exploit the performance potential of flash technology and provides faster data access compared to traditional SCSI protocols. The MDS-9132T is optimized for modern data centers requiring high-performance storage connectivity.
