Secondary Storage Design in ROBO

Use secondary storage for backup data to store backups on a different storage from the primary storage. The consolidated cluster uses vSAN for primary storage.

Table 1. Design Decisions on

Decision ID	Design Decision	Design Justification	Design Implication
ROBO-PHY-STO-006	Use a secondary storage solution for management and workload backup data.	Separate primary virtual machine storage from backup data in case of primary storage failure.	Secondary storage is required.
ROBO-PHY-STO-007	Set up the secondary storage with enough size and I/O for the backup operations during the scheduled backup window.	The backup and restore process is I/O intensive. The backup retention process is a storage-constrained operation.	The secondary storage solution has an impact on the backup and restore SLA.
