Which information is needed to restore the backup of a Cisco UCM publisher successfully?

TFTP server details are primarily for phone configuration files and firmware, not for restoring the entire Cisco UCM system backup.

Application credentials are for specific services or applications running on UCM, not the overarching system backup and restore process.

The security password, also referred to as the OS administrator password or platform password, is critically needed to restore a Cisco UCM publisher backup. This password encrypts the backup files and is required to gain the necessary access to the operating system during the restore procedure, ensuring the integrity and security of the restoration process.

While backup files are stored on an SFTP server (not typically FTP for security reasons), the FTP/SFTP server details refer to the location, not the essential security password needed to decrypt and apply the backup itself.
