A simple utility for backing up MongoDB databases to an S3 server. The utility of backing up a binary archive of your database to an S3 server is the security that your data is not lost through, depending on your server, replication.
First of all, this application uses the mongodump command, which is part of the mongodb-database-tools package. Refer to the documentation of your operating system to install this package.
Secondly, download the binary! Currently, three types of binaries have been released: Linux AMD64, Linux ARM and Windows AMD64. Feel free to open an issue if your architecture is not listed. Having said that, all you have to do is download the latest binary, for example if your distribution is Linux and your architecture is AMD64 :
curl -L https://github.com/Romitou/MongoS3/releases/latest/download/mongobackup-linux-amd64 -o mongobackup
Thirdly, make sure that the process is able to write files, especially in the temp folder, relative to where the process is located.
Next, write the environment file .env. Here are the values you need to specify:
S3_ENDPOINT: endpoint of your S3 server (do not include HTTP scheme)S3_ID: username or identifier to access the S3 serverS3_KEY: key or password to authenticate to the S3 serverS3_BUCKET: the bucket where the backups should be storedS3_RETENTION: the number of days your backups are retainedDISCORD_URL: the address of the Discord backup notification webhookMONGO_URI: the MongoDB address (see documentation) to connect to your cluster
Finally, you can run this application periodically (e.g. every day at midnight) to backup your database. This can be done using crontab, depending on your operating system.
