Knime File and Version lost

[mlauber71]

Could you give us more details? How was the ‘versioning’ done, did you give the workflows new names?

Some details about you machine and disk might help.

Then: KNIME basic version does not have a dedicated versioning or auto-save feature, the KNIME server has that.

I once suggested a do-it-yourself backup system but this is more a sorry excuse for a real backup.

@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.

[image] [image] Please note you will have to configure the Path variables and workflow names to your needs. I use local paths that will be created dynamically.

In general you should think about a backup system where your work gets saved, stored and versioned (think TimeMachine on Mac or Dropbox or OneDrive).
