Source notes citing this source

• The Disaster Recovery System supports up to 10 backup devices. in context
• A backup to a remote server that has not finished within 20 hours times out. in context
• DRS encrypts backup files with a randomly generated password, which is itself encrypted with the cluster security password. The security password in effect at backup time is needed to restore. in context
• DRS backups should be stored on a network device; virtualized deployments do not support tape drives. in context
• No OS Administration tasks should be performed while a backup is running, because DRS locks the platform API and blocks OS Administration requests. in context
• A DRS network backup device has a 'Number of backups to store on Network Directory' setting that controls how many backup sets are kept. in context
• DRS requires all cluster nodes to run the same version. in context
• The SFTP server bundled with Prime Collaboration Deployment is the only SFTP server that Cisco provides and tests and that Cisco TAC fully supports. Other third-party SFTP servers are not officially supported by TAC. in context
• The DRS backup device needs write access to the SFTP directory path, and the DRS Master Agent validates the username, password, server name and directory path when the device is configured. in context
• Cisco recommends running a new CUCM DRS backup whenever the cluster security password changes, because backups are encrypted with a key tied to that password. in context
• CUCM DRS writes encrypted cluster-level backups to SFTP servers (Cisco tests the SFTP server on Prime Collaboration Deployment), supports up to 10 backup schedules, and Cisco advises scheduling them off-peak. in context
