The file pup_safe.2fs contains the personal settings and your personal files, if the files are not stored on another partition (e.g. harddrive, USB stick). The backup is very simple. Either you start Puppy with the boot-option "puppy pfix=ram" or you start your old operating system (Windows). Then you copy the file onto the backup medium (e.g. another harddrive, USB stick, CD-ROM).
