Thanks for the info.
I have Acronis 2009 on my computer. No additional backup software on my wife's laptop yet.
Would you advise making the external into two partitions or just label the backups as his files and her files?
She has the reinstall disk from Dell for her computer so she just needs to back up her files that she does not want to lose.
I installed Windows 7 using the upgrade disk. I did a custom install from Win 7 RC, build 7100. So I will be looking to back up the OS so that I will not have to do a reinstall along with some files.
Again, appreciate your help
