Hi Prashanth, By default, NiFi Registry stores all data (flows, metadata, etc) in sub directories of its home directory (the install dir, which has sub dirs such as /conf, /lib, and /bin), so as long as you are taking regular backups of that directory you should be able to restore from a backup.
An alternative approach some people use is to use the GitFlowPersistenceProvider configured with a remote git repository, which means every flow is also synced to a remote github repository. This backup of flows can be used for disaster recovery in a few ways: - not released yet, but on master coming in the next release is a feature that will repopulate NiFi Registry's metadata directory from a git repository on startup - scripted using a tool such as the NiFi CLI, included in the NiFi Toolkit - some other approaches people have come up with, for example docker images with additional scripts that let a Registry container be initialized from a git repo and I believe there is a PR open now that adds additional capabilities to a git-backed Registry. Hope this helps! Let us know if you have additional questions.
