This project is no longer maintained. I lost interest in MongoDB some years ago and I can't drive an OSS project forward in my spare time without being passioned about it.
But MGOB lives on thanks to @maxisam. The new home of MGOB is https://github.com/maxisam/mgob
MGOB is a MongoDB backup automation tool built with Go.
- schedule backups
- local backups retention
- upload to S3 Object Storage (Minio, AWS, Google Cloud, Azure)
- upload to gcloud storage
- upload to SFTP
- upload to any Rclone supported storage
- notifications (Email, Slack)
- instrumentation with Prometheus
- http file server for local backups and logs
- distributed as an Alpine Docker image
MGOB is available on Docker Hub at stefanprodan/mgob.

Define a backup plan (yaml format) for each database you want to backup inside the config
dir.
The yaml file name is being used as the backup plan ID, no white spaces or special characters are allowed.

In order to restore from a local backup you have two options:
Browse mgob-host:8090/storage
to identify the backup you want to restore.
Login to your MongoDB server and download the archive using curl
and restore the backup with mongorestore
command line.
curl -o /tmp/mongo-test-1494056760.gz http://mgob-host:8090/storage/mongo-test/mongo-test-1494056760.gz
mongorestore --gzip --archive=/tmp/mongo-test-1494056760.gz --drop
You can also restore a backup from within mgob container.
Exec into mgob, identify the backup you want to restore and use mongorestore
to connect to your MongoDB server.
docker exec -it mgob sh
ls /storage/mongo-test
mongorestore --gzip --archive=/storage/mongo-test/mongo-test-1494056760.gz --host mongohost:27017 --drop
