Go SDK Snapshots reference

See the snapshot guide for workflows and examples. Use snapshot objects or references on cloud. Local operations also accept a group head, group:member, or artifact path.

Guest writeback

Set SnapshotCreateOptions.GuestFlush to msb.GuestFlushRequired, pass msb.WithBranchGuestFlush(msb.GuestFlushRequired) to Branch/BranchMany, or call source.PauseWithGuestFlush(ctx, msb.GuestFlushRequired). The default GuestFlushAuto flushes live disk-only captures, but adds no optional flush to full captures, branches, or pause. GuestFlushSkip retains mandatory storage barriers. A paused disk capture needs a matching prior flush; cloud rejects non-Auto policies. See guest flush policy reference. Disk capture, including SandboxHandle.Snapshot, requires a native library that supports guest-flush policies. Older libraries return an upgrade-required error, including for stopped disk captures. Full Auto capture and unrelated operations retain their compatibility.

Snapshot functions

Package-level helpers for snapshot artifacts. Access them through the exported Snapshot value, e.g. m.Snapshot.Create(ctx, ...).

Snapshot.Create()

func (snapshotFactory) Create(ctx context.Context, opts SnapshotCreateOptions) (*SnapshotArtifact, error)

Create a disk snapshot, or set Full to include memory and execution state. SnapshotCreateOptions.FromSandbox is required. An empty Name is generated; an empty Group uses the source sandbox’s name.

Parameters

ctxcontext.Context

Cancellation and deadline.

optsSnapshotCreateOptions

Name, source sandbox, labels, and integrity options.

Returns

*SnapshotArtifact

The created local or cloud snapshot.

Example

snap, err := m.Snapshot.Create(ctx, m.SnapshotCreateOptions{
    Name:            "deps",
    FromSandbox:     "baseline",
    Labels:          map[string]string{"stage": "post-deps"},
    RecordIntegrity: true,
})

Snapshot.CreateArchive()

func (snapshotFactory) CreateArchive(ctx context.Context, opts SnapshotArchiveOptions) (*SnapshotArchive, error)

Capture directly into an archive without installing a local snapshot.

Example

archive, err := m.Snapshot.CreateArchive(ctx, m.SnapshotArchiveOptions{
    SnapshotCreateOptions: m.SnapshotCreateOptions{
        Name:        "deps",
        FromSandbox: "baseline",
    },
    ArchivePath: "/tmp/deps.msb",
})

Snapshot.Open()

func (snapshotFactory) Open(ctx context.Context, pathOrName string) (*SnapshotArtifact, error)

Example

snap, err := m.Snapshot.Open(ctx, "baseline:deps")

Open an existing artifact by group head, group:member, or filesystem path. This validates metadata only; call s.Verify() for content checks.

Parameters

ctxcontext.Context

Cancellation and deadline.

pathOrNamestring

Group head or group:member selector or artifact directory path.

Returns

*SnapshotArtifact

The opened local or cloud snapshot.

Snapshot.Get()

func (snapshotFactory) Get(ctx context.Context, nameOrDigest string) (*SnapshotHandle, error)

Example

h, err := m.Snapshot.Get(ctx, "baseline:deps")

Look up a lightweight handle by group head, group:member, stable snapshot ID, descriptor digest, or artifact path. Global IDs and digests must resolve unambiguously.

Parameters

ctxcontext.Context

Cancellation and deadline.

nameOrDigeststring

Group head, group:member, stable snapshot ID, digest, or artifact path.

Returns

*SnapshotHandle

Lightweight handle returned by the active backend.

Snapshot.List()

func (snapshotFactory) List(ctx context.Context) ([]*SnapshotHandle, error)

Example

handles, err := m.Snapshot.List(ctx)
for _, h := range handles {
    fmt.Println(h.Digest(), h.ImageRef())
}

List snapshots visible through the active backend. Cloud lists managed snapshots; host-volume artifacts are opened explicitly by reference.

Returns

[]*SnapshotHandle

All indexed handles.

Snapshot.ListDir()

func (snapshotFactory) ListDir(ctx context.Context, dir string) ([]*SnapshotArtifact, error)

Walk a local directory and parse each subdirectory’s manifest without touching the local index. Cloud returns ErrUnsupportedOperation.

Parameters

ctxcontext.Context

Cancellation and deadline.

Directory holding snapshot artifact subdirectories.

Returns

[]*SnapshotArtifact

One artifact per parsed subdirectory.

Snapshot.Remove()

func (snapshotFactory) Remove(ctx context.Context, pathOrName string, force bool) error

Example

err := m.Snapshot.Remove(ctx, "baseline:deps", false)

Remove a snapshot through the active backend. Locally, removal also updates the index and refuses indexed children unless force is true.

Parameters

ctxcontext.Context

Cancellation and deadline.

pathOrNamestring

Group head, group:member, or artifact path.

forcebool

Delete even if the snapshot has indexed children.

Snapshot.Reindex()

func (snapshotFactory) Reindex(ctx context.Context, dir string) (uint32, error)

Example

n, err := m.Snapshot.Reindex(ctx, "/srv/snapshots")
fmt.Printf("indexed %d snapshots\n", n)

Walk dir and rebuild the local index from the artifacts it finds. Cloud returns ErrUnsupportedOperation.

Parameters

ctxcontext.Context

Cancellation and deadline.

dirstring

Directory to scan for snapshot artifacts.

)

Snapshot.Load()

function

func (snapshotFactory) Load(ctx context.Context, archive, dest string) (*SnapshotHandle, error)

Unpack a snapshot archive into the local snapshots directory or an explicit dest directory. Pass "" for the default destination. Cloud returns ErrUnsupportedOperation.

Snapshot.LoadMany()

func (snapshotFactory) LoadMany(
    ctx context.Context, archives []string, opts SnapshotLoadOptions,
) ([]*SnapshotHandle, error)

Import archives as one batch. Returns handles in input order. Dependencies resolve from the batch, the named group, or an explicit base; input order does not matter. All members are validated before publication.

Snapshot.GroupHead()

func (snapshotFactory) GroupHead(
    ctx context.Context, selector string,
) (*SnapshotHeadUpdate, error)

Read a group’s head, or select an exact member with group:member. Returns the group, previous and current snapshot IDs, reason, and whether the head changed. See group selection.

Import options

Options for SnapshotLoadOptions.

Option	Purpose
`Dest`	Parent directory containing groups. Defaults to the local snapshot store.
`Base`	External snapshot or standalone archive for missing dependencies.
`Group`	Destination group. Omit to create one group for the import.
`SetHead`	Select the imported tip, even with divergent ancestry. Defaults to false; requires a unique tip.

With divergent tips, the existing head stays selected; a new group has no head. Select a member explicitly. Identical members may be reused; conflicting identities fail. See archive imports.

SandboxHandle methods

Snapshots are taken from a metadata handle returned by GetSandbox. Local disk capture also supports a running or paused sandbox. Cloud requires a stopped persistent source.

_ = sb.Stop(ctx)
_ = sb.Close()

h, err := m.GetSandbox(ctx, "baseline")
if err != nil {
    return err
}
snap, err := h.Snapshot(ctx, "deps")

h.Snapshot()

func (h *SandboxHandle) Snapshot(ctx context.Context, name string) (*SnapshotArtifact, error)

Snapshot this sandbox into its default group with the given member name. Local live disk captures preserve the source’s running or paused state. Cloud requires a stopped persistent source. Use the returned artifact path or sandbox:member to open it later.

Parameters

ctxcontext.Context

Cancellation and deadline.

namestring

Member name within the source sandbox’s group.

Returns

*SnapshotArtifact

The created artifact.

Example

snap, err := h.Snapshot(ctx, "deps")

SnapshotArtifact methods

A local or cloud disk snapshot. The accessors below are plain field reads.

s.SaveTo()

func (s *SnapshotArtifact) SaveTo(
    ctx context.Context,
    outPath string,
    opts SnapshotSaveOptions,
) error

Bundle this snapshot through the active backend while preserving its typed identifier-or-path reference. Cloud returns ErrUnsupportedOperation.

err := snap.SaveTo(ctx, "/tmp/snap.tar.zst", m.SnapshotSaveOptions{
    WithImage: true,
})

s.CopyTo()

func (s *SnapshotArtifact) CopyTo(outputArchivePath string) *SnapshotCopyBuilder

Create a new archive from this snapshot’s disk data while replacing its labels and integrity metadata. The source snapshot is unchanged. Cloud returns ErrUnsupportedOperation when Save is called.

err := snap.CopyTo("/tmp/snap-copy.tar.zst").
    Labels(map[string]string{"environment": "test"}).
    RecordIntegrity(true).
    Save(ctx)

s.ID()

func (s *SnapshotArtifact) ID() string

Stable opaque snap_... identity.

s.Verify()

func (s *SnapshotArtifact) Verify(ctx context.Context) (*SnapshotVerifyReport, error)

Verify the snapshot’s complete state closure. File state recomputes recorded upper-layer integrity. Checkpoint state validates the complete checkpoint closure and returns its root in Checkpoint.

Returns

*SnapshotVerifyReport

Recomputed digest and upper-layer status.

Example

report, err := snap.Verify(ctx)
if err != nil {
    return err
}
if report.Upper.Kind == "not_recorded" {
    fmt.Println("snapshot has no recorded payload integrity")
} else {
    fmt.Println(report.Upper.Digest)
}

s.Reference()

func (s *SnapshotArtifact) Reference() string

Stable backend-relative value. Prefer passing the SnapshotArtifact itself to RestoreSandbox so its typed reference is preserved as well.

s.ReferenceKind()

func (s *SnapshotArtifact) ReferenceKind() string

Returns "id" or "path". Most callers can pass the artifact itself and never inspect this value.

s.Digest()

func (s *SnapshotArtifact) Digest() string

s.Fstype()

func (s *SnapshotArtifact) Fstype() string

Filesystem type inside the upper layer.

s.Parent()

func (s *SnapshotArtifact) Parent() *string

Parent digest, or nil if this snapshot has no parent. Returns a defensive copy.

s.CreatedAt()

func (s *SnapshotArtifact) CreatedAt() string

RFC 3339 creation timestamp.

s.Labels()

func (s *SnapshotArtifact) Labels() map[string]string

User labels recorded at creation. Returns a defensive copy.

s.SourceSandbox()

func (s *SnapshotArtifact) SourceSandbox() *string

Best-effort source sandbox name, or nil. Returns a defensive copy.

SnapshotHandle methods

A lightweight handle returned by the active backend. The handle retains a stable reference used by Open, Remove, and SaveTo.

Open the underlying snapshot metadata using this handle’s stable reference.

Returns

*SnapshotArtifact

The opened artifact.

h.Remove()

func (h *SnapshotHandle) Remove(ctx context.Context, force bool) error

Backend-reported stored payload size, or nil if unknown.

h.ReferenceKind()

func (h *SnapshotHandle) ReferenceKind() string

Returns "id" or "path" for the handle’s backend-neutral reference.

h.CreatedAt()

func (h *SnapshotHandle) CreatedAt() time.Time

Snapshot creation time, decoded from the index’s Unix timestamp.

Restore

Restore into a new detached sandbox. Disk boots fresh; full resumes execution. See restore examples and progress.

Example

child, err := m.RestoreSandbox(ctx, "api:baseline", "api-restored", m.WithForked())

Control	Purpose
`WithForked()`	Share unchanged full-snapshot memory.
`WithSnapshotDiskOnly()`	Boot only the saved disk.
`WithSnapshotBase(base)`	Supply an archive dependency.
`RestoreSandbox`	Return the restored sandbox.
`RestoreSandboxWithProgress`	Return event and result channels.

Image, replacement, and startup-command options are not accepted. Full restore requires matching CPU and memory settings, keeps captured network devices, and cannot apply a new guest security profile. Use disk-only restore to change these. Full restore rejects missing external filesystems and additional disks by default. Use WithAllowMissingResources() to resume with unavailable devices and warnings. This is separate from strict/relaxed validation of supplied mappings; inheritance does not waive missing backing. Root and owned storage remain required.

Destination options

Option	Purpose
`WithRestoreCPUs, WithRestoreMemory`	CPU count and memory in MiB. Full restore must match capture.
`WithRestoreNetworkPolicy`	Replace host traffic filtering; guest DNS and TLS settings stay unchanged.
`WithRestoreMaxConnections`	Concurrent TCP limit; zero means unlimited.
`WithRestoreDisableNetwork`	Remove the NIC. Rejected for full snapshots that captured one.
`WithRestoreSecurityProfile`	Guest security profile. Disk boot only, including an explicit default profile.
`WithRestoreMaxDuration, WithRestoreIdleTimeout`	Lifetime and idle limits. Omitted means unlimited; zero expires immediately.
`Volumes, CapturedVolumes`	Map host volumes or select captured private volumes.
`Ports`	Bind destination TCP or UDP ports.
`Vsock`	Bind destination vsock endpoints.
`User, LogLevel`	Default user for new execs and host runtime log level.
`WithDangerouslyInheritResources`	Explicitly inherit host resources. Disabled by default.
`WithAllowMissingResources()`	Allow unavailable external filesystems or additional disks, with warnings. Full restore otherwise requires their bindings.
`WithExternalMountPolicy`	Validate supplied filesystem mappings: strict (default) or relaxed. Does not grant access.

Omitted controls retain destination defaults. Durations use time.Duration, rounded up to seconds. Binding fields belong in WithRestoreConfig(RestoreConfig{...}); nil pointers mean omitted. Network policy accepts factory results or NetworkConfig with only Rules, DefaultEgress, and DefaultIngress.

Compaction

Compact a local sandbox’s root or owned disks. See compaction for examples and recovery requirements.

Options and results

Option	Purpose
`Disk`	Select one owned disk by guest path; `/` selects the root.
`RootDiskOnly`	Select only the root. Cannot combine with the disk selector.
`Layers`	Oldest sealed layers to merge, including the base. Minimum two; omit for all. Excludes the writable layer.
`DryRun`	Preview without changing storage.

Defaults to the root and owned data disks; excludes named/external volumes and directories. Requires a running or fully stopped local sandbox. Fewer than two sealed layers means no change; no eligible disks returns an empty result with zero counts.Results include aggregate counts and per-disk entries keyed by GuestPath. MaterializedBytes counts copied bytes, not reclaimed space. Times are microseconds: per-disk TotalUs covers preparation; aggregate TotalUs also includes switching; PauseUs measures the shared VM pause.
