Percona Backup for MongoDB vs dat: What are the differences?

Developers describe Percona Backup for MongoDB as "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. On the other hand, dat is detailed as "Real-time replication and versioning for data sets". Dat is an open source project that provides a streaming interface between every file format and data storage backend.

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