Adapter: CrossWatch

Local backup adapter that stores watchlist/history/ratings on disk for rollback and restore.

CrossWatch adapter is a local backup provider. It stores watchlist, history, and ratings as JSON in your config folder.

Use it as a safety net:

• Backup: Plex/Emby/Jellyfin/Trakt/SIMKL/MDBList/TMDb → CrossWatch

• Restore: CrossWatch → any provider

Nothing runs “automatically”. CrossWatch adapter only does work when it’s used in a pair.

What it supports

• Features: Watchlist, History, Ratings

• Auth: none (local only)

• Storage:

  • Current state: /config/.cw_provider/

  • Snapshots: /config/.cw_provider/snapshots/

• Restore granularity: per feature (pick different snapshots per feature)

Storage layout

Current state files:

• /config/.cw_provider/watchlist.json

• /config/.cw_provider/history.json

• /config/.cw_provider/ratings.json

Snapshots are timestamped:

• YYYYMMDDThhmmssZ-watchlist.json

• YYYYMMDDThhmmssZ-history.json

• YYYYMMDDThhmmssZ-ratings.json

When snapshots are created

Snapshots are only created when CrossWatch needs to change its local data.

Typical case:

• CrossWatch is the target in a run.

• The run applies add/remove operations.

• If Auto snapshot is enabled, CrossWatch snapshots the old state first.

Settings

Go to Settings → CrossWatch Tracker.

Basic behavior

• Enabled: toggles the provider for use in pairs.

• Retention (days): 0 keeps snapshots forever.

• Auto snapshot: snapshots before writes.

• Max snapshots per feature: 0 = unlimited.

Restore snapshots (per feature)

Pick one snapshot for each feature:

• Watchlist snapshot

• History snapshot

• Ratings snapshot

Latest (default) uses the most recent snapshot for that feature.

What gets written to config

"crosswatch": {
  "enabled": true,
  "retention_days": 30,
  "auto_snapshot": true,
  "max_snapshots": 64,
  "restore_watchlist": "latest",
  "restore_history": "latest",
  "restore_ratings": "latest"
}

What “restore” means

Selecting a snapshot does not push changes to other providers.

It only changes what CrossWatch exposes as its current state:

• The chosen snapshot is copied into the main JSON for that feature.

• A restore happens only when you run a pair where CrossWatch is the source.

Snapshot selection “arms” the restore. Running a pair “applies” the restore.

Common workflows

1

Undo a bad sync (restore ratings)

1. Open Settings → CrossWatch Tracker.

2. Set Ratings snapshot to a time before the bad run.

3. Save.

4. Run a pair: CrossWatch → target provider, enable Ratings only.

2

Roll back watchlist only

1. Set Watchlist snapshot to an older file.

2. Keep History/Ratings on Latest.

3. Run a pair: CrossWatch → target provider, enable Watchlist only.

3

Migrate state to a new provider

1. Pick snapshots you trust for the features you want.

2. Run a pair: CrossWatch → new provider.

3. Start one-way first. Use one feature. Then expand.

Tips and limitations

• CrossWatch is local. Remove /config/.cw_provider/ and you lose backups.

• Low retention + frequent runs will prune older snapshots quickly.

• This is extra protection. It does not replace provider-side backups (if any).

Recommended baseline:

• Enabled: On

• Auto snapshot: On

• Retention: 30–90 days

• Max snapshots per feature: 64

• Restore selection: Latest, until you need a rollback
