v10.4 Release Notes

Release Date: 2 August 2021

New Features

Immutable Local Repository

The Immutable Local Repository feature allows you to make recovery points in a local Backup Repository immutable for a specified period of time. Immutable backups are protected from deletion, modification, and encryption by ransomware. 

Two-Factor Authentication

You can enable Two-Factor Authentication for each user accessing the product web interface. This update provides an additional layer of security against malicious access to backup data by requiring a verification code in addition to the username and password when logging in.
