`validate_only`	`bool`	Validate and return the result without writing anything.

#Snapshot

Field	Type	What it is
`name`	`string`	`orgs/{org}/projects/{project}/envs/{env}/snapshots/{snapshot}`.
`meta`	`ResourceMeta`	Resource metadata.
`spec`	`SnapshotSpec`	Desired state. Required.

#ResourceMeta

Field	Type	What it is
`labels`	`map<string, string>`	Caller-writable, indexed labels (AIP-122 label rules).
`annotations`	`map<string, string>`	Caller-writable, unindexed annotations.

#SnapshotSpec

`source_lease`	`string`	The running lease to capture. Required.
`include_memory`	`bool`	Capture process memory too. Refused UNIMPLEMENTED until the microVM runtime exposes memory snapshots.
`retention`	`duration`	Delete the snapshot after this long; default 7 days, at most 30 days.

#SnapshotStatus

Field	Type	What it is
`observed_generation`	`int64`	The generation this status was computed from. Output only.
