What I do is back up the complete poser folder too 2 external hard drives, one is a hard drive I use regularly and the other is for backup only.  Then if I need to restore poser I just drag the folder to the drive I want it on and the most i have to do is fill in the serial number.  Then I backup all downloads and the files I have created too DVD, twice, I do it twice because I have lost data backed up to CD or DVD, Steve
