BackupMod vs Minecraft Backup

BackupMod is a free, self-hosted Minecraft server mod for creating and restoring automatic or manual backups. Administrators can schedule several backups each day, check the time until the next run, and set a retention limit that removes the oldest files automatically. Backups can be named, renamed, listed, deleted, or restored by name or as the latest backup. Restoring a selected backup disconnects all players and stops the server. Files and folders can be excluded and later included again. An upload command downloads a ZIP from a direct URL, but Google Drive links do not work. Commands are limited to server operators or authorized players, with normal and detailed logging options. Backups stay in the server’s local backups/ folder. Installation uses the server’s mods folder; Modrinth lists Fabric, dedicated servers, and Minecraft Java Edition 1.21.8–1.21.10.

Minecraft Backup is a Linux script for backing up Minecraft server world folders. It can create tar archives or use the restic backend, and connects to servers managed with screen or tmux, as well as servers with RCON or Docker RCON enabled. The script works with vanilla servers and does not require plugins. Backups can be scheduled with cron; the README includes an hourly example. For older backups, users can choose no deletion, sequential deletion of the oldest backup, or thin retention. Thin retention keeps the last 24 hourly and 30 daily backups, then uses available space for weekly backups. Backups are stored locally, and restoration uses tar extraction for tar files or restic restore for restic backups. The script can post backup status messages in Minecraft chat. It requires tar and a compression program such as the default gzip; RCON also requires xxd. Player data can become out of sync with world data during backups, potentially duplicating or losing items. RCON is recommended because it waits for the server to confirm saving is complete. The README also warns that Minecraft bug MC-217729 can cause a backup to fail.
