==============================
Backup feature already exists in FoundationDB and is detailed here :ref:`backups`, any use of fdbbackup will refer to this feature.
Both fdbbackup and Disk snapshot backup tools provide a point-in-time consistent backup of FoundationDB database, but, they operate at different levels and there are differences in terms of performance, features and external dependency.
Both fdbbackup and Disk snapshot backup tools provide a point-in-time consistent backup of FoundationDB database, but they operate at different levels and there are differences in terms of performance, features and external dependency.
fdbbackup operates at the key-value level. Backup involves copying of all the key-value pairs from the source cluster and restore involves applying all the key-value pairs to the destination database. Performance depends on the amount of data and the throughput with which the data can be read and written. This approach has no external dependency, there is no requirement for any snapshotting feature from the disk system. Additionally, it has an option for continuous backup with the flexibility to pick a restore point.
