A 200-player Rust server writing to a 1TB NVMe array generates roughly 40-90GB of daily churn between world saves, plugin logs, and player databases. A conventional nightly full backup of that dataset takes 12-18 minutes and, on most game hosts, runs during exactly the window when your highest-value players are online. The fix is not a bigger backup window \u2014 it is a three-layer strategy where each layer covers a different failure mode.<\/p>\n\n\n\n
Layer 1: RAID Is Availability, Not Backup<\/h2>\n\n\n\n
RAID survives disk death. It does not survive a corrupted world file, an accidental rm -rf<\/code>, or a bad plugin update that overwrites the save. Treat RAID as uptime insurance only.<\/p>\n\n\n\n

For game workloads, RAID 10 on 4-8 NVMe drives with a hardware controller carrying a battery-backed or supercapacitor-backed write cache is the sweet spot. The cache absorbs save bursts that would otherwise stall the tick loop waiting on parity computation.<\/p>\n\n\n\n
Layer 2: Snapshots for Rollback Speed<\/h2>\n\n\n\n
Snapshots are for the mistake you made ten minutes ago. A ZFS or Btrfs snapshot of a 200GB world costs milliseconds and near-zero space until data diverges.<\/p>\n\n\n\n
# Hourly ZFS snapshot of the game data dataset, keep 48\n0 * * * * \/sbin\/zfs snapshot gameserv\/world@$(date +\\%Y\\%m\\%d-\\%H)\n\n# Keep 48 hourly, drop older\n15 * * * * \/sbin\/zfs list -H -o name -t snapshot gameserv\/world | head -n -48 | xargs -r -n1 \/sbin\/zfs destroy<\/code><\/pre>\n\n\n\n
Snapshot before every plugin update and every world migration \u2014 no exceptions.<\/li>
Never snapshot the live database file alone; snapshot the directory so WAL and data stay consistent.<\/li>
Remember snapshots on the same physical array do not protect against hardware loss. They protect against human loss.<\/li>
Watch snapshot space: high-churn log directories can consume 20% of the pool within hours.<\/li><\/ul>\n\n\n\n
Layer 3: Offsite Replication for Real Disaster<\/h2>\n\n\n\n
The offsite copy is the one that saves you when the datacenter loses power, the host is reimaged by mistake, or ransomware hits. It must be on different hardware, in a different facility, ideally on a different provider.<\/p>\n\n\n\n
The incremental ZFS send is the standout here: 2-8GB per hour over a 1Gbit link is comfortable, and because it transfers only changed blocks, compression keeps the pipe utilization low enough that it never competes with player traffic.<\/p>\n\n\n\n
Restore Drills: The Part Everyone Skips<\/h2>\n\n\n\n
A backup you have never restored is not a backup, it is a hope. Run a restore drill monthly into an isolated environment.<\/p>\n\n\n\n
Spin up a spare box, restore the latest offsite snapshot, boot the game server, confirm the world loads and player inventories are intact.<\/li>
Time the whole drill end to end. If it exceeds 60 minutes, your RTO promise to players is fiction.<\/li>
Verify the database replica is consistent, not just the world files.<\/li>
Document the exact commands in a runbook the on-call admin can follow at 3am.<\/li><\/ul>\n\n\n\n
