Workflow Recovery

[christianlondon]

Context: we have a Workspace with different Workflows, it has been working for more than a year without complications, last week we upgraded to KNIME 4.7 version, at first it generated an error but I followed the following recommendation Contacting Software Sites has encountered a problem - #3 by Snowy
and the upgrade was successful.

The Workspace worked correctly for a week but a few days ago I opened and some Workflows did not appear, as if they had been deleted. But they are nowhere to be found. I don’t think it’s because of the upgrade either but I need to get my Workflows back.

These are the folders belonging to the Workflows before the incident:

And folders now:

Question: Is there any way to recover lost Workflows?
Isn’t there a recycle garbage can for flows, to see the deleted Workflows?

Not sure what the solution here is, but if things get desperate you can always do a system restore.

@christianlondon could you give us more details, what kind of system is this, is it on a shared folder? The basic KNIME versions does not have an integrated recycle bin or recovery mechanism (yet) - the KNIME server although does. Concerning backup and recovery you might want to explore these threads:

Avoid unintended node deletions

@dnguyen welcome to the KNIME forum. Sorry to hear about your troubles. One thing you could do is build yourself some simple backup system to store versions of your workflow as a simple ZIP file with a timestamp (not super fancy but effective): Then backup and versioning is a thing in all businesses since all things that can go wrong might do so at any time. So regardless of KNIME or other tools it is always good to have a backup strategy ready. In the case of KNIME it is that the basic vers…

Restore Knime workflows

@evert.homan_scilifelab.se I can offer up these threads. Unfortunately if the workflows would not integrate themselves into KNIME like this you might have to revert to a backup. Can you tell us more about your system and the circumstance where the data is being stored (is it some sort of cloud drive?).

I have suggested a small DIY backup system you might want to consider:

Copy/Move Files Node

@zedleb I created and example where the KNIME workflow (or workflow group) is being zipped into a file with a current timestamp. And can later be restored to a (separate) folder.
