modal.SandboxSnapshot
=====================

    class SandboxSnapshot(modal.object.Object)

> Sandbox memory snapshots are in **early preview**.

A `SandboxSnapshot` object lets you interact with a stored Sandbox snapshot that was created by calling `._experimental_snapshot()` on a Sandbox instance. This includes both the filesystem and memory state of the original Sandbox at the time the snapshot was taken.

hydrate 

    hydrate(self, client=None)

Synchronize the local object with its identity on the Modal server.

It is rarely necessary to call this method explicitly, as most operations will lazily hydrate when needed. The main use case is when you need to access object metadata, such as its ID.

_Added in v0.72.39_: This method replaces the deprecated `.resolve()` method.

from_id 

    from_id(cls, sandbox_snapshot_id, client=None)

Construct a `SandboxSnapshot` for an existing snapshot ID.

**Parameters**

sandbox_snapshot_id str

Snapshot ID returned when the snapshot was created.

client "modal.client.Client | None"

Modal client to use; defaults to `Client.from_env()` when omitted.

**Returns**

A `SandboxSnapshot` handle (hydration validates the ID when used).
