A full state backup is the appropriate choice when an engineer needs to perform a backup and restore in Cisco UCS for disaster recovery purposes. This type of backup includes a snapshot of the entire system and is saved as a binary file. Importantly, full state backups are encrypted, ensuring that passwords and other sensitive information are not stored as clear text12. While TFTP (Trivial File Transfer Protocol) is not secure by itself, the encryption of the full state backup file provides the necessary security for the passwords within the backup.
