MongoDB Backup Docker Container

This Docker container automates backups for a MongoDB database using mongodump

Usage

Instructions

1. Pull the image:

   docker pull ghcr.io/berry-13/mongodb-backup:latest

2. Run the Docker container:

   docker run -d \
     --name mongo-backup \
     -e MONGO_URI=mongodb://root:example@your-mongo-host:27017 \
     -e BACKUP_INTERVAL=86400 \
     -v /path/to/backup:/backup/data \
     mongo-backup

   Replace /path/to/backup with the local directory where you want to store the backups

Configuration

• The MONGO_URI environment variable specifies the MongoDB connection string
• The BACKUP_INTERVAL environment variable specifies the interval between backups in seconds (default is 86400 seconds, or 24 hours)
• Check the .env.example for the RETENTION_STRATEGY
• Backups are stored in the /backup/data directory inside the container

Backup Script

The backup.sh script performs the following actions:

• Creates a timestamped backup directory
• Runs mongodump to backup the MongoDB database.
• Removes backups older than 7 days

Restore a Backup

To restore a backup, use the mongorestore command:

docker run --rm -v /path/to/backup:/backup/data mongo mongorestore --uri "mongodb://root:example@your-mongo-host:27017" /backup/data/<backup-folder>

Replace /path/to/backup with the local backup directory and <backup-folder> with the desired backup directory
