https://www.learncisco.net/courses/cucm-basics/serviceability-backup-and-restore/backing-up-and-restoring-cucm.htmlThe Disaster Recovery System (DRS) is a feature within Cisco Unified Communications Manager (UCM) that allows administrators to create and manage backups of their UCM data, configurations, and settings. These backups are essential for quickly recovering from a system failure, disaster, or outage.
When using DRS, backup files are stored in a remote disk location, rather than on the local disk of the UCM server. This ensures that backup files are not lost in the event of a hardware failure or other system issues.
DRS supports several protocols for storing backup files, including SFTP, CIFS, and NFS. These protocols provide secure and reliable ways to transfer backup files to a remote location.
SFTP (Secure File Transfer Protocol) is a network protocol that provides secure file access, file transfer, and file management. It uses SSH (Secure Shell) encryption to protect the confidentiality and integrity of data in transit.
CIFS (Common Internet File System) is a protocol used to share files across networked devices. It is often used in Windows environments and provides support for authentication, authorization, and access control.
NFS (Network File System) is a distributed file system protocol that allows remote access to files over a network. It is commonly used in Unix/Linux environments and provides support for file locking, caching, and access control.
Therefore, the correct answer to the question is B. remote disk on the SFTP server, as SFTP is one of the supported protocols for storing backup files in the DRS of Cisco UCM.
