NiFi 2.x and "file-manager.sh"

[#1]

Hello Team,

We are planning to upgrade our use of NiFi from 1.x to 2.x, and we are looking very much forward to try the new version.

In NiFi 1.x we are using the "file-manager.sh" script in the toolkit for making backup and restore. It appears that this file is no longer present in NiFi 2.x.

1) Has this file been removed from NiFi 2.x permanently, or do you know of any plans for adding it to NiFi 2.x in a future release? 

2) If the file is not coming to NiFi 2.x will there be any replacement file for making backup/restore, or should we collect files for backup ourselves such as flow.json.gz?

Best Regards

Welcome to the Cloudera Community.

The Apache NiFi community made the decision to remove nifi-toolkit-admin in NIFI-11316 which included:

1. File Manager
2. Flow analyzer
3. Node manager
4. Notify

There are no plans to bring these back in NiFi 2.x. 

NiFi deployments should protect the NiFi repositories from data loss through the use of RAID.  Taking backups of the NiFi repositories (mainly flowfile, content, and provenance) makes little sense as the contents of these repositories continuously change.  Backup of the config files in the NiFi conf directory and maintaining a copy of the flow.json.gz would allow you to recover a node.   Keep in mind that the flow.json.gz is the same on all nodes in a NiFi cluster so it can be restored from any node to a new node.
