comment Are there any benifits to backing up when you have all the original installation disks?
what, exactly, do you think that you are backing up? Back up only your data, if that is what you think that you need. Copy your data to USB stick, or even configure the programs to save tto USB stick; or a sepatrate partition which you can backup. But, be aware that you are unkikely to save program options. Again - what do you want to save/preservee/protect - maybe "backup" is not the best word ...

comment Encryption in an embeddded system
+1 @DavidWachtfogel I take your point about wanting to prevent tampering, not reading - but can't I do both? I think I didn't explain well - the firmware is on a microprocessor in the machine and runs from there. If I need to load new f/w then, yes, it comes from the SD card, but is an encrypted exe & hard to hack (I hope). I take your point about auditing & there will be a lot ofback end s/w associated with the sales databse. Thansk for your feedback. What do you suggest, in concrete terms?
