Resilience and backup

Hello,

What resilience and backup capabilities do LMI have in place?

For example, if you were to have 50 users in an account and someone was to remove them by accident, how would it be recovered, can it even be recovered (at LMI support leve)?

If 100 machines were removed from the computers section, do LMI have snapshots so the customer can restore?

What advanced mechanisms are in place to prevent accidental or intentional removals and\or damage?

Many thanks
