I purchased TI 9 a few months ago. I am now thinking of purchasing TI 10, but I am not clear about the real differences. Are there any really major differences? My only real interest is in being able to recover from a hard drive failure, due to either mechanical problems or virus attacks. I run windows 2000 on a dual core, dual processor AMD Opteron computer with 2 scsi drives. I have other windows 2000 computers, but they are not really critical, as far as backup is concerned. I also run a Linux machine, but it is ancient and only an 800 MHZ Pentium III. The perfect solution would be a system that would backup everything each night, either to separate drives or perhaps a common drive on one computer (like the Linux box), but I suspect that either does not exist or would be prohibitively expensive for an individual.
