What to exclude

Skip regenerable files so archives stay smaller and restores stay focused on world data.

  • Cache folders — rebuild after a restart
  • Dynmap tiles — regenerable, often huge
  • Spark profiles — diagnostics only
  • Logs — add size, rarely help restores

Minecraft Backup Size Estimator guide

Estimate Minecraft server backup size and monthly storage from world size, plugin count, player data, retention, and compression — then pick a sensible schedule with example cron lines.

Plan storage before you run out

World folders grow quietly until backups fill the disk and the server stops saving. This estimator models a single backup and your retained daily/weekly copies so you can buy the right disk or trim retention before it hurts.

Adjust world size, world count, plugins, and player data, choose gzip or zstd-style compression ratios, and see a clear monthly storage estimate.

Schedules that respect peak hours

Run heavy backups in off-peak windows. Keep enough daily copies to recover from a bad plugin update, plus weekly copies for longer rollback. The tool suggests cron-style examples and prune ideas so old archives do not pile up forever.

Exclude regenerable caches such as Dynmap renders and profiler outputs from frequent backups — they inflate size without helping a restore.

Restore drills matter

A backup you have never restored is a hope, not a plan. After you set retention, practice restoring a world copy on a test instance. Store at least one copy off the machine that runs the live server.

LiteByte and other hosts may offer snapshot features — use this estimator to understand how much space your own archive policy needs on top of those snapshots.

Common questions

Should I back up Dynmap files?
Usually exclude render caches like Dynmap and Spark outputs from frequent backups — they are large and regenerable.
How many daily backups should I keep?
Many servers keep 3–7 daily copies plus a few weekly archives. Raise retention only if you have disk headroom and a real need for longer rollback.
Is the size exact?
No. It is an estimate from your inputs and typical compression. Check real archive sizes after the first few runs and tune retention.
