using Win 7 -64 bit and just installed Instant Recovery Installation was smooth and as a previous user of FdISR the Gui was very familiar . I intend to use IR in the same way as Peter with a stripped down secondary snapshot and archives on a separate drive. Main reason is that in 7 64 bit, my drive is already quite big and I don't want to add another 60 gb to every image I do, doubling backup times. Last time with FdISR I created my stripped down snapshot during the build of the pc but this time with a new fully set-up pc I need to go backwards. Being a bit paranoid on messing too much without suitable safety nets (and yes , I do have an image), I wanted to test the new IR first before stripping almost everything from the pc. So I created of course my first snapshot (called secondary) and an archive of the prime snapshot. At this stage primary and secondary were exact copies. In order to test and to keep it simple, I changed the desktop wallpaper and removed two files and added another txt file, then updated the secondary form primary. At this stage I should have identical primary and secondary with an archive reflecting the original set-up before the desktop changes. Then I rebooted to secondary. To my surprise while the files had been changed as expected (removed and added), the desktop wallpaper did not work. The new wallpaper appeared very briefly to be replaced by my original slide show desktop background. Not believing my own eyes I took a screenshot based on Control Panel - Personalisation and rebooted to primary to confirm. The config is different - took another screenshot from primary desktop personalisation. I then repeated the copy / update primary to secondary. Again the copy action was done and while I was surprised to see the time necessary to do this (in fact I had nothing changed) -these were the details Scanned: 57.5 gb, Added 41.6 mb = 336 files, Removed 58 mb - 120 files, replaced 689 mb - I assume these changes are all system changes of log files etc that windows generates ? After finishing the copy/paste I once again rebooted into secondary - same result - the desktop config is not identical to primary snapshot. Is there any good reason why this should happen? Are changes like these config settings not part of the copying/backup? I have had nothing but good experiences with the original FdISR and was looking forward to adding the new version back to my safety net.
