Vein Save Management & Backups

Managing Server Saves

Reliable save management in Vein is the difference between routine maintenance and catastrophic community loss, so backups must be automated and regularly restore-tested.

Save Location

Vein dedicated server saves are typically found in:

Manual Backups

1. Stop the server process.
2. Compress the SaveGames folder into a ZIP or move it to a backup directory.
3. Restart the server.

Corruption Prevention

To avoid corrupted saves, always use the /Save command before shutting down host processes. Never terminate the server process abruptly if possible.

Save Reliability Framework

Build save handling around consistency checks, off-node replication, and restore drills. Many hosts create backups but never validate them, which only surfaces corruption during real incidents when recovery time matters most.

• Snapshot timing: Take pre-maintenance and post-maintenance snapshots for each change window.
• Storage policy: Keep local fast restores and remote long-retention archives.
• Recovery drills: Perform scheduled test restores on a staging server each month.

Operational Checklist

Treat this topic as a repeatable server operation, not a one-time change. Schedule changes during lower traffic, announce maintenance windows, and keep a rollback snapshot before each update. If your server is modded, validate changes on a staging copy first so startup logs, world loading, and player joins are confirmed before production rollout.

Validation Steps

• Capture baseline metrics: Record CPU, RAM, and average player ping before changes.
• Apply one change at a time: Avoid batch edits that make root-cause analysis difficult.
• Review logs after restart: Check for version mismatch and dependency warnings immediately.
• Run a real join test: Confirm fresh clients can connect and complete core gameplay actions.
• Observe for at least 24 hours: Validate behavior under peak load, not only right after reboot.

Performance and Stability Notes

Most hosting incidents come from resource spikes combined with configuration drift. Keep restart cadence predictable, review world/save growth weekly, and cap optional systems that generate extreme entity counts. When performance drops, compare with your last known-good baseline and revert recent high-risk changes quickly to reduce downtime.

Backup and Rollback Policy

Use automated daily backups plus pre-change snapshots for risky operations. Keep at least one off-node copy and test restore procedures routinely. A practical retention strategy is 7 daily, 4 weekly, and 2 monthly restore points. If a change causes instability, roll back first, stabilize service, and then reattempt with a narrower test scope.

Game-Specific Hosting Notes

• Experimental updates: Keep controlled rollout windows and verify save compatibility.
• Admin permissions: Audit privilege assignments after patches to prevent accidental escalation.
• World integrity: Validate persistence after restarts and crash recovery before reopening.
