Hello, Congratulations on the Acronis tools (TI & DD). It was a bit diifcult at first to get to understanding how TI works and how to use all the info that's provided in the user's guide, but after reading the very helpful "beginner's guide" by Grover H and sticky thread, I feel like I have entered "Acronis TI thinking mode". I think I have a general view of how TI works and how to use it, now I would like to understand more in detail. I would appreciate any explanations that would enable me to understand how the two following TI tools can be helpful for backing up our system : 1. "System State" tool. - This "sounds" like it makes a backup like the incremental or differential, but I imagine that's not what it does. Can someone kindly help me understand the function of this utility, in comparison to "my computer" backup? 2. "Application Settings". - I have the following scenario : a Sony Vaio laptop with one C: drive (140GB) in it and Vista Home Premium 32B as system. There is a hardware/driver problem (built in camera not working anymore) and it might very well be required that I return the C: disk / system to factory settings. For doing this there is the built in Sony/Vista recovery center, which offers to either restore the whole system or just the C: drive. Quick note: Setting back to factory settings is not such a problem for me as it will give the opportunity to "clean the house" > I acquired the laptop 7 months ago and was a total beginner; now that I'm a bit more advanced I wouldn't mind starting on a "clean page" with the system and C: drive. There are surely things I have done illogically without being aware at the beginning and which might have caused a little mess here and there. Also, now that I use TI, I'll make an image of the system with factory settings then another with my own application settings so that I have a larger "backup repertoire" to choose from if things get "rough" one day. So my question is : - when we backup using TI "Application Settings" tool, we obtain as a result a file that can then be restored once the C: disk has been set back to factory settings, correct? - this result file will then restore the "user settings" related to applications, correct? (naturally, as mentioned in the TI user guide, applications will have to be re-installed using the setup exe files we have kept). - what would be interesting to know is "where" does the TI tool "take" or "copy" data, to serve as backup for application settings? In : users > username > app data? In : Windows Registry? Elsewhere? I'm very curious to know basically where the system stores application data and settings and if TI will backup everything needed. So that when we restore the "application settings" backup we made through TI, our applications will be configured to user specific settings again, and not to default application settings. I imagine that backing up application settings and data cannot be achieved simply by "copying/pasting" the user file with the app data...that's why we need the TI tool, right? Thank you. PS I posted a similar question in this thread, but thought of making a new thread here to open up a thread title so that new users like me can find more easily info related to these two tools in TI. Hope it was a good idea.
