[feature request] automatic backup creation of workflow.knime

In some rare cases, powerfailure, hardware crash, etc. this error may appear:

java.io.IOException: Unable to parse xml: line=1: Content is not allowed in prolog.

xml: URI=java.io.BufferedInputStream@342e812c

dtd: URI=null

and is due to a corrupt workflow.knime file. This has been discussed here previously.

And even though all the other files and settings are in place, the workflow is bascially unusable after this (recreating a large, well, even some small, workflows is a major pain, if at all possible). Especially problematic if you don’t have a recent backup or any at all.

This could be easily remedied (at to least to a large extent) by simply creating a backup of the workflow.knime by Knime itself. E.g. at certain timeintervalls. It would be enough with a .bak version. Maybe not directly at startup, if that is where a potential problem lies to begin with. But after a few minutes the first backup? Any single occasion would already make a difference.

Thanks in advance.
