#Backup scheduler in linux how to#
In this tutorial, we’ve learned how to implement and test a strategy for nightly logical MongoDB backups. You’ve now successfully implemented and tested this MongoDB backup strategy. Let’s insert a document into a dummy restaurants collection, which will automatically be created (as it doesn’t yet exist): Since we haven’t inserted anything into the database yet, there are no collections, and we’re brought back to the prompt with no output. Let’s list the collections present in the test database: T20:30:57.320+0000 I CONTROL ** We suggest setting it to 'never'īy default, the shell connects to the test database. T20:30:57.320+0000 I CONTROL ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'. You’ll see the following Mongo shell prompt: MongoDB shell version: 3.2.19įor more comprehensive documentation, see

If you already have some collections and documents stored in your database, feel free to skip this step and continue on to Step 2.įirst, connect to the running database using the MongoDB shell: mongo If you’re starting from a clean MongoDB installation and haven’t stored any data yet, you should first insert some sample data into a dummy restaurants collection for test purposes.
Once you’ve logged in to your Droplet, have MongoDB up and running, and have created your Space, you’re ready to get started.

We’ll then show how to compress and upload the resulting serialized data backup files to DigitalOcean Spaces, a highly redundant object store. In this guide, we’ll demonstrate how to back up a MongoDB database using mongodump, a built-in logical backup tool. The optimal solution will depend on your recovery point and time objectives and database scale and architecture. As logical backup tools read all data being backed up through memory, they can be slow and cause non-trivial additional load for particularly large databases.ĭesigning an effective backup and recovery strategy often involves trading off performance impact, implementation costs, and data storage costs with recovery speed, data integrity, and backup coverage.

They offer granular control over what data to back up and restore and backups are often portable across database versions and installations. mongodump or pg_dump) to export data from the database into backup files, which are then restored using a corresponding restore tool (e.g. Logical backups involve using a tool (e.g.
They are instrumental in backing up large databases quickly, especially when used in tandem with filesystem snapshots, such as LVM snapshots, or block storage volume snapshots, such as DigitalOcean Block Storage Snapshots. In general, there are two broad categories of backups: filesystem-level (“physical”) backups and logical backups.įilesystem-level backups involve snapshotting the underlying data files at a point in time, and allowing the database to cleanly recover using the state captured in the snapshotted files. Regular database backups are a crucial step in guarding against unintended data loss events.
