![]() Mongodumb normally creates a binary export of the selected contents. In this case one can opt to use some coordinated backup and restore processes that maintain the atomicity guarantees of transactions across shards such as MongoDB Cloud Manager, MongoDB Ops Manager and MongoDB Cloud Manager. Mongodump cannot be used for a sharded cluster with sharded transactions in progress especially for versions later than 4.2 due to the fact that mongodump does not maintain the atomicity guarantee of transactions across the shards. It is also possible to have partial backups based on a collection, query, changing a replica set storage engine to a standalone or syncing from production to development environment. mongodumb usage ranges from three angles:įor a complete backup and recovery strategy, mongodump is used alongside the mongorestore tool whereby the latter is used in the restoration process. It can also be downloaded as a separate tool from the MongoDB Download Center. It is used in creating binary exports of the database contents. Mongodump is a utility bundled with the MongoDB database. In this article, we will only discuss the mongodumb utility, what it entails, how to perform and recovery using this utility and lastly what merits and disadvantages is it associated with. MongoDB Management Service (MMS) which is a fully managed cloud service that provides a continuous backup for MongoDB.Įvery approach has its pros and cons dependending on the complexity of implementation, Recovery Time Objective, Recovery Point Objective and cost.Filesystem snapshots whereby data is collected from the database files and then stored in another cloud centre.mongodumb, a utility bundled with the MongoDB itself.In the end, this can provide directions towards fixing application errors that are leading to such. Besides, backups may be created to ensure a company is compliant with organizations and government regulations that may dictate the need to access critical and essential business data after any technical outage.īackups can also be used to ensure data integrity and consistency through close comparison of the previous backups with the current database data. Database backups help administrators to restore the database to its operational state along with its data logs. Backups are achieved through database replication using either database utilities or some external setups. Restoration of the operational database is only possible if there is a backup in place. Database backup for any organization should be an important undertaking for ensuring business continuity in any case of database catastrophe.
