NativeBackup beta 0.1.1

NativeBackup beta 0.1.1 is a Valheim backup plugin that adds fast in-game backup triggers on top of Valheim's native backup system.

Ground Truth (Current Build)

NativeBackup currently provides:

Esc-menu Backup button integrated under Save.
Console commands: sb.backup, sb.backup world, sb.backup char, sb.list.
Automatic timed backups (optional) via config.
Native backup creation through Valheim save APIs.
Save-before-backup synchronization through current-version ZNet save flow.
Single-flight execution with cooldown guard.
Minimalist UX messaging with duration in completion/failure toasts.
Flashing top-right backup indicator while backup is running.

Backup Pipeline

Every trigger path (button, command, timer) follows the same pipeline:

Resolve requested target intent.
Enter coordinator gate (no overlap, 5-second cooldown).
Trigger native save sync via ZNet.Save(false, true, false) on main thread.
Wait for ZNet.SaveDoneTime to advance.
Create native backup(s) for selected target(s).
Emit concise completion/failure toast with elapsed time.

Important behavior details:

Explicit target commands are strict.
sb.backup world will not silently fall back to character.
sb.backup char will not silently fall back to world.
Backup sync is current-version only and does not use legacy trigger discovery fallbacks.
If save completion cannot be confirmed within timeout, backup is canceled to avoid stale snapshots.

User Experience

Design goals are minimal and informative:

No center-screen backup spam.
Flashing top-right backup badge while backup is running.
Backup button is grayed out while backup is running or cooldown is active.
Concise top-left toast on completion/failure/cancel with timing.

Examples:

Backup complete (1.8s): world 'MyWorld' and character 'test'.
Backup failed (1.2s): requested target unavailable.
Backup canceled (2.0s): could not confirm current save state.
Backup on cooldown.
Backup already running.

Target Rules

Hosted local world:
sb.backup world backs up world.
sb.backup char backs up character.
Esc button and sb.backup attempt both.
Non-host/client session:
sb.backup world is blocked.
Character backup paths remain available when character save is resolvable.

Commands

sb.backup - backup current available targets.
sb.backup world - world only (host required).
sb.backup char - character only.
sb.list - lists legacy archive index entries.

Cooldown behavior:

Backup actions use a 5-second cooldown window.
During cooldown, the Esc-menu Backup button remains disabled (grayed out).

Configuration

Config file: com.aloncifer.nativebackup.cfg

BackupIntervalMinutes: timed backup interval. 0 disables scheduler.
MaxBackupsPerSave: maximum number of native backups kept per save target.

Retention behavior:

Native backups are pruned after each successful backup so only the newest MaxBackupsPerSave entries remain per save.
Setting the value to 0 disables pruning.

Build and Install

Build target: .NET Framework 4.6.2.
Build command: dotnet build NativeBackup.sln -c Release.
Output: src/bin/Release/net462/NativeBackup.dll.
Install DLL to BepInEx plugins folder.

Notes

The backup badge uses IMGUI; icon glyph rendering can vary by system font.
Native restore/list rendering is still Valheim-owned UI behavior.
This build targets current Valheim save APIs and intentionally removes legacy trigger compatibility paths.
