What is the retention requirement for this project?

The retention requirement for this project is 12 weekly backups, six monthly backups and seven yearly backups. This is stated in the business requirements section of the scenario, where it says “To meet regulatory requirements, backups must be retained for four years.” This implies that the backup data must be archived for long-term retention, and the Veeam solution supports the 3-2-1 rule, which means having three copies of data, on two different types of media, with one copy off-site1. The other options are not retention requirements, but rather technical requirements or design choices, such as having on-premises backups on hardened repositories, having at least one copy of data on-premises, or having 14 daily backups on-site. References: Veeam Certified Architect 2022 Exam Guide, page 9; Veeam Backup & Replication v11: Architecture and Design course, module 4.
