I'm looking for easiest & MOST RELIABLE method to BU OS & installed programs partitions, AND the restore or copying BUs to original partitions / HDDs ACTUALLY works. I just spent days w/ HP printer software / registry issues. HP support was useless this time. 1) Imaging software seems to always have potential glitches. Any new program installed or Windows update, as examples (Vista x 32 / 64) seems to potentially cause BU software problems - Acronis, Ghost, etc. - read the thousands of posts on the subject. 2) I don't care WHAT the best method / solution costs, long as it's easy as possible (scheduled automatic is better), AND most reliable method available. I'm partially disabled & though have advance ability to figure out almost any computer problem, have NO time or physical ability for such. I have NO time to trouble shoot why Acronis, Ghost, etc., is no longer working / restoring properly. 3) What do IT pros use for simplest, most reliable BU & restore? 4) My desktop has open bays for several more HDDs (but not my laptop). Maybe buying 1 or more giagantic HDDs & just copying the entire partitions & have DOS prgm(s) capable of copying entire partitions back, if windows or HDD fails completely? For laptop, maybe large external HDD? Thanks for suggestions.
