Advanced Synchronization

Conflict Resolution Strategies

DeckSaves uses intelligent algorithms to handle sync conflicts:

Timestamp-Based Resolution

  • Primary method: Compares file modification times
  • Tolerance: 2-second difference accounts for filesystem precision
  • Fallback: Size comparison when timestamps are very close
  • Smart logic: Preserves both versions in version history

Manual Conflict Resolution

When automatic resolution isn't sufficient:

# Example conflict scenario
Local file:  modified 2025-01-15 14:30:00 (size: 1.2MB)
Remote file: modified 2025-01-15 14:29:58 (size: 1.3MB)
Resolution:  Size difference detected, local version preferred, remote preserved in history

Bidirectional Merging

Smart Sync performs sophisticated merging:

  • Manifest analysis: Compares version histories
  • Version preservation: Keeps all unique versions from both sources
  • Conflict flagging: Identifies files that exist in both with different content
  • User notification: Reports merge results with detailed statistics

Advanced Sync Modes

Directory Snapshot Mode

Creates unified versions of entire save directories:

  • Single version per sync: Treats all save files as one unit
  • Atomic restoration: Restores complete game state at once
  • Compression: tar.gz archives reduce storage space
  • Consistency: Prevents partial save restoration issues

Individual File Mode (Legacy)

Tracks each save file separately:

  • Granular control: Restore individual save files
  • Mixed versions: Different files can be from different time points
  • Backward compatibility: Supports old version format
  • File-level operations: Pin, delete, restore individual files

Intelligent Batching

Optimizes sync operations for performance:

  • Change detection: Only sync files that have actually changed
  • Batch timing: Groups multiple changes into single operations
  • Rate limiting: Prevents API overwhelm with rapid changes
  • Priority queuing: Critical games can be prioritized

Storage Optimization

Compression Strategies

DeckSaves implements multiple compression techniques:

Archive Compression

  • Format: gzip compression for directory snapshots
  • Ratio: Typical 60-80% size reduction for save files
  • Speed: Optimized for fast compression/decompression
  • Integrity: Built-in checksum verification

Delta Compression (Future)

Planned advanced compression for incremental backups:

  • Block-level deduplication: Only store changed portions
  • Version linking: Reference unchanged data from previous versions
  • Storage efficiency: Massive space savings for large save files
  • Fast restoration: Quick reconstruction of any version

Storage Tiering

Implement intelligent storage management:

Hot/Cold Storage

  • Hot storage: Recent versions kept for fast access
  • Cold storage: Older versions moved to cheaper, slower storage
  • Automatic tiering: Based on age and access patterns
  • Retrieval optimization: Predictive pre-loading of likely-needed versions

Cleanup Policies

Advanced cleanup beyond basic age/count limits:

// Example cleanup policy configuration
{
    "max_versions_per_file": 10,
    "max_version_age_days": 30,
    "keep_pinned_versions": true,
    "auto_pin_strategy": "Weekly",
    "cleanup_policies": {
        "keep_first_of_day": true,
        "keep_achievement_versions": true,
        "compress_old_versions": true,
        "archive_ancient_versions": true
    }
}

Deduplication

Eliminate redundant data across games:

  • Content-based deduplication: Identical files stored once
  • Cross-game efficiency: Common save file patterns deduplicated
  • Hash-based identification: SHA256 content addressing
  • Reference counting: Safe deletion when no longer referenced

Automation & Scripting

Scheduled Operations

Automate routine maintenance tasks:

Automatic Sync Schedules

  • Time-based: Sync every X hours/days
  • Event-based: Sync on game launch/exit
  • Conditional: Sync only when files change
  • Smart scheduling: Avoid sync during active gameplay

Maintenance Automation

# Example automated maintenance script
#!/bin/bash
# Daily maintenance routine
decksaves cleanup --policy=conservative
decksaves verify --repair-corruption
decksaves optimize --compress-old-versions
decksaves report [email protected]

Command Line Interface

Advanced users can script operations:

# Sync specific game
decksaves sync --game="Cyberpunk 2077" --versioned

# Batch operations
decksaves sync --all --exclude="Test Game"

# Version management
decksaves pin --game="Elden Ring" --version=latest --reason="Before NG+"
decksaves restore --game="Dark Souls" --version="2025-01-15_pre-boss"

# Storage operations
decksaves cleanup --dry-run --verbose
decksaves migrate --from=local --to=s3 --bucket=my-saves
