The new Proxmox Tape Backup System, provides an easy way to copy datastore content to tapes. Proxmox Backup Server supports all Linear Tape-Open generation drives, thus, it includes hardware encryption.
Users can now set up Two-Factor Authentication (TFA) which adds another layer of security to the authentication process, making it harder for cybercriminals to access the network and take over accounts. The two-factor authentication can be activated or configured via the GUI, by the users themselves or by a system administrator.
Downloading a directory from a file-level backup will now produce a compressed ZIP archive, reducing bandwidth and local space required.
