7.5 Storage
7.5.1 Snapshots
Tenants can create one snapshot of a vApp or individual VM including its running state (memory). The following are snapshot design considerations:
• Org VDC requires enough free storage capacity for the maximum size of the snapshot, which is equal to the total size of provisioned disks and memory (if a snapshot of memory is chosen as well).
• Taking a snapshot has disk I/O performance impact. In time the size of snapshot grows, which must be accounted for capacity management. It is also disables network reconfiguration options on VM.
• It is possible to remove ‘Create, Remove and Revert a Snapshot’ from tenant roles.
