Required: At least Daily Backups of WeKan ® database with mongodump. Bugs, updates, users deleting list or card, harddrive full, harddrive crash etc can eat your data. There is no undo yet. Only newest WeKan ® is supported. Please report all new bugs immediately. Sandstorm WeKan ® is rarely affected by any Standalone WeKan ® security issues. If you use Standalone WeKan ® on public Internet, it's better use Snap x64 automatic updates and restore from backup when needed, than to leave old vulnerable manually updated WeKan ® running.
