Star Rupture SaveSync Host Migration Guide 2026

SaveSync is Star Rupture's revolutionary feature allowing seamless host migration. Players can transfer world saves without losing progress or causing downtime.

🔄 SaveSync Overview

  • Seamless Transfer: Move host between players without stopping
  • No Progress Loss: All buildings, research, and items preserved
  • Automatic Sync: Save state transfers automatically
  • Multiplayer Coordination: Perfect for rotating host responsibilities

How SaveSync Works

Technology Overview

SaveSync uses peer-to-peer save synchronization:

  • Background Sync: Save data syncs while playing
  • Cloud Backup: Automatic upload to secure storage
  • Version Control: Track save versions for rollback
  • Checksum Verification: Ensure data integrity during transfer

SaveSync Architecture

Current Host

  • Holds master save file
  • Sends sync data to players
  • Authorizes host transfer

New Host

  • Receives sync data
  • Downloads save state
  • Becomes new master host

Cloud Backup

  • Stores save securely
  • Enables recovery
  • Version history available

Using SaveSync as Host

Enabling SaveSync

Access server settings in-game and enable SaveSync:

# Enable SaveSync
SaveSyncEnabled = true
AutoSyncInterval = 300  # seconds
MaxSaveHistory = 10

Initiating Host Transfer

  1. Open Star Rupture main menu
  2. Select "Multiplayer"
  3. Click "SaveSync" tab
  4. Choose player to transfer host to
  5. Confirm transfer authorization
  6. Wait for sync completion
  7. New host becomes server owner

Host Transfer Process

🔄 Transfer Steps

  1. Authorization: Current host accepts transfer
  2. Data Sync: Save state uploads to cloud
  3. Verification: Checksum validates data integrity
  4. Download: New host receives save file
  5. Activation: New host launches server
  6. Confirmation: All players reconnect to new host

During Transfer

  • Players: Stay connected during transfer
  • Pause: Game pauses briefly during sync
  • Progress: Show progress indicator to all players
  • Rollback: Automatic rollback if transfer fails

Using SaveSync as Player

Receiving Host Transfer

  1. Wait for transfer notification from current host
  2. Accept host transfer request
  3. Verify save version
  4. Download save data
  5. Launch game as new host
  6. Invite other players to rejoin

Player Responsibilities

ScenarioAction Required
Becoming New HostEnsure good internet, sufficient hardware
RejoiningUse new host's server details to reconnect
Conflict ResolutionVote on disputed transfers if needed
Save Backup:Keep personal backups before transfer

Troubleshooting SaveSync

Common Issues

Transfer stuck at 0%?

Check firewall ports (27015, 27016). Ensure both hosts have stable internet connection.

Players get desync after transfer?

Save version mismatch. Ensure all players are running same Star Rupture version.

Save won't download for new host?

Check available disk space. Ensure new host has Star Rupture installed and updated.

Transfer fails repeatedly?

Check server logs for errors. Try reducing sync interval or disabling compression.

Lost progress after transfer?

Use SaveSync history to rollback to previous save. Check for corrupted files.

Best Practices

Host Rotation

  • Schedule Transfers: Plan host changes during low-activity times
  • Communication: Notify all players of scheduled transfers
  • Backup Strategy: Keep multiple save versions available
  • Test New Host: Verify new host's internet before transfer
  • Gradual Transfer: For large groups, consider staggered transfers

Save Management

  • Regular Backups: Backup saves before major transfers
  • Version Control: Label saves with dates and versions
  • Cleanup: Remove old saves periodically to save space
  • Archive Important: Save special milestones separately

Network Optimization

  • Bandwidth: Minimum 100 Mbps upload recommended for SaveSync
  • Wired Connection: Use Ethernet instead of WiFi
  • QoS: Prioritize Star Rupture traffic on your router
  • Port Forwarding: Ensure ports 27015-27017 are open

Dedicated Server Considerations

SaveSync on Dedicated

Dedicated servers provide optimal SaveSync performance:

  • Always Online: Server available 24/7 for syncing
  • High Bandwidth: Faster transfers and less downtime
  • Stable IP: No IP changes disrupts SaveSync
  • Storage Performance: NVMe SSD for faster save/load operations

Dedicated Server Benefit: With dedicated hosting, SaveSync eliminates the need for host migration entirely - the server is always available!

Frequently Asked Questions

Do I need dedicated server for SaveSync?

No, SaveSync works on peer-hosted servers. However, dedicated servers provide better performance and reliability.

Can I use SaveSync solo?

SaveSync is designed for multiplayer. Single-player games don't need it.

How long does a transfer take?

p>Typically 1-5 minutes depending on save size and connection speeds. Large saves may take longer.

Can multiple players transfer host at once?

No, transfers are sequential. One player must be active host at a time.

What happens if transfer fails?

Automatic rollback to previous save. Current host remains unchanged. Players retry transfer.

Is SaveSync data secure?

Yes, encrypted transfer with checksum verification. Save history allows rollback if needed.
