I have a couple of questions about Nandroid backups. I had originally rooted my droid using the Universal Androot application. As part of that process I loaded Rom Manager and flashed the ClockWork recovery. Because of all the stuff I have been reading here and I problem that I ran into, I decided to back out that process and root my phone using the procedure written up by MotoCache1. Which, by the way, I have to say was a fantastic write up. If you are thinking of rooting your phone, he has really provided you with everything you need to know. Anyway, I now have SPRecovery on my phone and this leads me to my question about Nandroid backups. I had several backups done by the ClockWork recovery and new ones done by SPRecovery. I have noticed that the file structure between the two is different, which leads to my first question: The backups made with one version cannot be used by the other version? The ClockWork recovery Nandroid backup has files like system.img and the SPRecovery’s Nandroid backup has system.tar. My second question is specifically about SPRecovery. When doing the backup I noticed that not all of the entries were selected by default. I am assuming that if I want a complete backup that I can use to restore my phone back to some earlier (and presumably working) state, that I should have everything selected. Is that in fact the case? I am not trying to debate which version of recovery is better. That is really a matter of personal preference and I am sure that they both do what needs to be done. I just want to make sure that I am using the SPRecovery correctly.
