mongo-dumper is a simple cli script to easily dump, compress, encrypt and optionally upload your mongodb database/cluster. The tool is using the --archive and optional the --gzip option from mongodump to create a backup. Keep this in mind if you restore your backup with mongorestore.
In order to run the script you need to have gnupg, the minio client (mc) and mongodump installed (version should match the mongodb server).
