Advanced Backup Strategies
Protect your years of work with professional redundancy. Learn about off-site backups, S3 integration, and regional data protection.
1. The Golden Rule of Data: 3-2-1
In the IT world, we follow the "3-2-1" rule for data safety: have at least 3 copies of your data, on 2 different media types, with 1 copy stored off-site. While Deduck's automated backups are excellent for daily restores, a professional admin should always have an independent copy of their world.
2. Deduck Automated Backups
By default, Deduck allows you to create scheduled backups that are stored on our high-speed storage network. These backups include your world folders, plugin configurations, and database snapshots. These are "hot" backups, meaning they are taken while the server is running without causing noticeable lag, thanks to our specialized filesystem snapshots.
3. Off-site Backups via S3
For ultimate safety, you should send copies of your data to a third-party provider like Amazon S3, Backblaze B2, or Google Cloud Storage.
- Why? If there is a massive data center outage or a fire (though unlikely), your off-site copy remains safe.
- How? Use a plugin like DriveBackupV2. It can automatically compress your world and upload it to your choice of cloud storage every night.
4. Database (SQL) Backups
If your server uses a MySQL or MariaDB database for LuckPerms or CoreProtect, backing up the files in the /world folder isn't enough. You must also perform a "SQL Dump".
Manual SQL Backup:
Use a tool like mysqldump or the export function in PHPMyAdmin/HeidiSQL to create a .sql text file. This file contains all the commands needed to recreate your database from scratch.
5. Incremental vs. Full Backups
A Full Backup saves everything every time. This is safe but wastes disk space. An Incremental Backup only saves the files that have changed since the last backup. Most Minecraft backup plugins use a hybrid approach, taking a full backup once a week and incrementals daily.
6. Testing your Backups
A backup is only useful if it actually works. We recommend performing a "Fire Drill" once a month:
- Create a temporary new server instance.
- Download your latest backup file.
- Upload it to the temporary server and see if it launches without errors.
- Log in and verify that player inventories and world structures are correct.
7. Handling Data Corruption
Sometimes, a server crash or a faulty plugin can "corrupt" aSpecific chunk. If this happens, your server might crash every time a player enters that area. In this scenario, don't restore the whole server! Instead, use a tool like MCA Selector to identify the corrupt .mca file and delete only that specific region, or restore just those specific files from your backup.
