JustBackup
by Tlagz
JustBackup is a NeoForge mod that makes automatic and manual backups of a world, with a lightweight design and a limit on how many backups are kept.
What it does
JustBackup creates backups of the world on a configurable interval and also lets a player or operator trigger one by hand. The mod keeps no more than a set number of backups, removing the oldest ones automatically once the limit is reached. Chat messages can announce when a backup is created, and that message is optional. Every player and the server need a copy of the mod. Files are published for NeoForge only, across 11 release versions, 1.21 – 1.21.10, under All rights reserved, and the mod is not open source.
Key features
Automatic backups

Backup limit
A maximum number of backups is kept, and older backups are deleted automatically when the limit is exceeded.
Light footprint
The mod is built to stay small and to add little to the cost of running the game, with options kept to a minimum.
