It is a common practice that before a backup can be stored in the cloud or on a dedicated backup server, it has to be prepared first locally and later copied to the destination. Fortunately, there are ways to skip the local storage entirely and stream MongoDB backups directly to the destination. 0 document(s) failed to restore. %H-%M)/db2.zst

MongoDB is a non-relational document database that provides support for JSON-like storage. When you have multiple copies of your data on different database servers — or even better, in different data centers worldwide — replication provides a high level of fault tolerance in case of a disaster.

This results in smaller backup sets, reducing storage requirements, time to take the backup, and network usage, as compared to full backups.
