Backup operations using mongodump is dependent on the available system memory.When the WiredTiger storage engine is used in a MongoDB instance, the output will be uncompressed data.The default location for backups is the dump/ folder. The mongodump command will overwrite the existing files within the given backup folder.It is recommended to use the corresponding versions of mongodump and mongorestore in backup and restore operations. To ensure maximum compatibility, use Extended JSON v2.0 (Canonical) for mongodump metadata files.If you want to capture documents within a view, use the “–viewsAsCollections” flag. When it comes to backing up read-only views, mongodump only captures metadata of views.These indexes must be rebuilt after a restoration process. The backup operation will exclude the “local” database and only captures the documents excluding the index data. The mongodump utility directs its read operations to the primary member of a replica set, making the default read preference to primary.The following list breaks down the expected behaviors and limitations of the mongodump utility. You can find the full list of platforms that mongodump is compatible with from their documentation. The mongodump utility is supported on most x86_64 platforms and some of ARM64, PPC64LE, and s390x platforms. Mongodump guarantees compatibility with MongoDB 4.4, 4.2, 4.0, and 3.6. The new iterations of mongodump are released as a separate utility in MongoDB Database Tools. A sharded cluster of MongoDB deploymentsīefore MongoDB 4.4, mongodump was released alongside the MongoDB server and used matched versioning.Mongodump can export data from both mongod and mongos instances, allowing you to create backups from: The utility can be used for creating binary export of the database contents. The mongodump is a utility for creating database backups. We can utilize snapshots if the file system supports it.Īnother way is to use a tool like rsync where we can directly copy the data files to a backup directory. In this method, you merely keep copies of the underlying data files of a MongoDB installation. Mongodump is an ideal backup solution for small MongoDB instances due to its ease of use and portability. These files can be restored using the mongorestore utility. Mongodump is a simple MongoDB backup utility that creates high fidelity BSON files from an underlying database. Ops Manager provides the same functionality as Cloud Manager but it can be deployed as an on-premise solution. Cloud Manager enables easy backup and restores functionality while providing offsite backups. MongoDB Cloud Manager or Ops ManagerĬloud Manager is a hosted backup, monitoring, and automation service for MongoDB. If MongoDB is hosted in MongoDB Atlas cloud database service, the Altas service provides automated continuous incremental backups.Īdditionally, Altas can be used to create cloud provider snapshots, where local database snapshots are created using the underlying cloud providers’ snapshot functionality. Here are the several options you have for backing up your data in MongoDB: Use the right-hand menu to navigate.) Built-in backups in MongoDB (This article is part of our MongoDB Guide. We’ll look briefly at the options, but then we’ll show you how to utilize one particular option-MongoDB mongodump-for the backup process. MongoDB offers multiple inbuilt backup options depending on the MongoDB deployment method you use. Typically, you create database backups by replicating the database, using either: Data backups act as a safety measure where data can be recovered or restored in case of an emergency. Maintaining backups is vital for every organization. Automated Mainframe Intelligence (BMC AMI).Control-M Application Workflow Orchestration.Accelerate With a Self-Managing Mainframe.
