He has since become fascinated with open source database technologies first mastering PostgreSQL & MongoDB and later MySQL & MariaDB. (2 replica sets--3 servers each, and also 1 config server and 1 mongos server). The mongodb consistent backup is using mongodump utility as the backup method, and the backup can be restored using mongorestore. Making proper backups of the database is a critical task. It is a logical backup method, similar to mysqldump in MySQL or pg_dump in PostgreSQL database. XML Word Printable. In the context of MongoDB, there three main strategies for backing up MongoDB: 1. mongodump, a utility bundled with the MongoDB database 2. The user must exist on each node in the replica set and also in the config server if you use sharded cluster architecture. Percona Backup for MongoDB consists of two components, the pbm-agent that needs to be installed on each node and the pbm as a command line interface to interact and run the backups.The pbm-agent coordinate between the database nodes and running the backup and restoration process. The architecture uses a region with one availability domain and regional subnets. © Copyright 2014-2020 Severalnines AB.
