jonathon [1] filed a deletion request for qt5-fsarchiver [2]: There is a severe bug which may result in deletion of the root partition: https://sourceforge.net/p/qt4-fsarchiver/discussion/1196657/thread/f382575a/... Developer's response is here: https://sourceforge.net/p/qt4-fsarchiver/discussion/1196657/thread/f382575a/... , essentially "don't kill the backup process or your partition will be wiped". This seems needlessly potentially harmful and likely represents a severe breakage in the underlying software. Removing the "cancel" UI button isn't a fix for potential data loss given the variety of ways of closing or interrupting a program's operation.
