This approach has no external dependency, there is no requirement for any snapshotting feature from the disk system. Performance depends on the amount of data and the throughput with which the data can be read and written. 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. Backup vs Disk snapshot backupīackup feature already exists in FoundationDB and is detailed here :ref:`backups`, any use of fdbbackup will refer to this feature.īoth 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.įdbbackup operates at the key-value level. Restore behaves as if the cluster were powered down and restarted. ![]() ![]() Restore is achieved by copying or attaching the disk snapshot images to FoundationDB compute instances. The disk snapshot backup tool orchestrates the snapshotting of all the disk images and ensures that they are restorable to a consistent point in time. The prerequisite of this feature is to have crash consistent snapshot support on the filesystem (or the disks) on which FoundationDB is running. IntroductionįoundationDB's disk snapshot backup tool makes a consistent, point-in-time backup of FoundationDB database without downtime by taking crash consistent snapshot of all the disk stores that have persistent data. The disk snapshot backup can be used for test and development purposes, for compliance reasons or to provide an additional level of protection in case of hardware or software failures. This tool leverages disk level snapshots and gets a point-in-time consistent copy of the database. This document covers disk snapshot based backup and restoration of a FoundationDB database. ![]()
