Percona Backup for MongoDB vs PostgreSQL Modeler: What are the differences?

Percona Backup for MongoDB: A fully supported, open source, community backup tool for performing consistent hot backups in MongoDB. It is a distributed, low-impact solution for achieving consistent backups of MongoDB sharded clusters and replica sets. It supports Percona Server for MongoDB and MongoDB Community v3.6 or higher with MongoDB Replication enabled. It is an alternative for users who want a fully supported community backup tool, but do not want to pay for MongoDB Enterprise and Ops Manager. With easy command-line interface, you can perform consistent backup/restore of clusters and non-sharded replica sets, and improve cluster backup consistency. This saves you time and effort if you are implementing MongoDB backups for the first time; PostgreSQL Modeler: PostgreSQL Database Modeler. Open source data modeling tool designed for PostgreSQL. No more DDL commands written by hand.

Percona Backup for MongoDB and PostgreSQL Modeler belong to "Database Tools" category of the tech stack.
