X full backups, then delete oldest

Well that's the point really - what is backup software for? Correct to backup ones software/OS. To me this is where Acronis has lost the plot. My only use for TI is as insurance for the unthinkable i.e. HD failure or system corruption. If the worst happens then I simply restore a full image and hopefully everything is back as it was. Why mess around with only backing up system state or data etc. when restoring a full image works so well. Forget all the bells and whistles and just concentrate on the core application.
