Hello, I just bought a sp4 to replace my laptop. I have a question on how you guys handle incidents where in you need to revert back to an old working state of Windows. My backup strategy is proven very effective on traditional laptops: I have 2 partitions; C is for programs and windows and D is for my files and everything else. I configured my docs, desktops, etc. to be stored in D drive so everything is transparent; if it is on my desktop; it is in my D drive. I use Acronis to create an IMAGE backup of just the C drive and I do normal file level backups for the files in D. If I get a virus in C or windows suddenly crashes due to a program I installed; I can easily restore an image of C and be right where I left off with my latest files untouched. Do you guys use something like this to protect your setup and files? I also have a cloud account (gdrive) where all my small files that I update everyday are kept. So I have local backups and extra copies in the cloud. I haven't used any of the windows backup and restore features as I don't trust them yet; or just used to the old and trusted method. But I'm willing to embrace the changes since we are now moving into smaller and lighter... although less customisable machines.
