In modern vSphere environments, consider moving toward , VMFS with snapshots , or VVols – each offers different recovery capabilities. But regardless of the underlying technology, a well-documented recovery plan and regular drills are the true keys to minimizing downtime when disaster strikes.

Introduction In any vSphere environment, the datastore is the fundamental storage container that holds virtual machines (VMs), ISO images, templates, and other critical files. When a datastore becomes inaccessible, corrupted, or suffers data loss, the impact is immediate and severe: VMs may fail to power on, storage vMotion operations halt, and in worst-case scenarios, production workloads are completely offline. When a datastore becomes inaccessible
From vSphere Client or CLI:
