Starlight Preserved
by starmun
Starlight Preserved backs up a Fabric server world on a schedule, flushing data to disk before each archive is written.
What it does
The backup runs at a configurable interval, so a server owner rarely loses more than the time since the last archive. Before zipping, the mod flushes world data to disk so the copy is clean. If the drive does not have enough free space for a backup, that run is skipped and a warning is logged. Players online receive a notification when a backup starts and finishes.
Settings live in a simple JSON config file, where the interval and the number of backups to keep can be tweaked. Starlight Preserved requires Fabric Loader and Fabric API. The server must run it, while players may leave it out and still join. Files target 26.1 only, with the latest Fabric build 0.0.2 released on 2026-03-31 on the alpha channel. The mod is published under All rights reserved and is not open source, although its source code and issue tracker are public.
