Question

Options

• ADedupe appliance leveraging vendor API for access
• BPublic cloud storage with S3 object-lock for immutability
• CWindows repository using ReFS integration, single-use credential and persistent VSS snapshot

Explanation

The best option for the primary backup repository design that fits the requirements in the case study is a Linux Repository using XFS integration, single-use credentials, and immutability. A Linux Repository is a type of backup repository that uses a Linux server as a backup target. A Linux Repository can leverage XFS integration to enable fast creation and transformation of synthetic full backups by using XFS file system features such as reflink and copy-on-write. A Linux Repository can also use single-use credentials to enhance security by generating unique credentials for each backup job session. A Linux Repository can also provide immutability and ransomware protection for backup files by using Linux access control mechanisms such as immutable flag or chattr command.
