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.

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.
