Duel-RegenStorage
Where snapshots live on disk and what the files are.
With persist-snapshots: true (the default), snapshots are written under the plugin's folder:
config.yml
Arena1.snap
Arena2.schem
The two formats
| Format | Written when | What it is |
|---|---|---|
.snap | use-fawe is off | The plugin's own compressed format. Stores block states with a palette, so even a million-block arena compresses to a small file. Includes container contents and sign text |
.schem | use-fawe is on | A standard Sponge schematic, written through WorldEdit. You can open it with WorldEdit itself if you ever want to |
Lifecycle
- Written in the background right after each capture, via a temp file and rename, so a crash mid-write cannot corrupt anything.
- Deleted automatically when the snapshot is consumed by a restore or removed with
/duelregen remove. - Loaded at startup. A file present at boot with
snapshot-each-match: truemeans the server went down mid-match, and the arena is restored automatically. See Crash Recovery.
Good to know
- Files are named after the arena. If an arena name ever contains characters that cannot be a filename, that snapshot stays memory-only and the console says so.
- A snapshot file from a different Minecraft version is skipped with a warning rather than restored wrongly.
- The files are small (kilobytes to a few megabytes). There is no database and nothing else to back up; the whole plugin state is
config.ymlplus this folder.
