http://forum.xda-developers.com – I have an AT&T Atrix2 with official ICS. It's rooted and I have A2 Bootstrap installed and the CWM mod on boot (JY Daddy's mod). I also have taken a full back up using CWM. How do I know if this backup is good? ----The backup process created this path on my SD card "clockworkmod\backup\2013-02-\ ----I copied this as-is into my computer to free up space on my SD card. I plan to copy it back to my SD card if I need to restore. Is this OK? I see files: .android_secure.vfat.tar, cache.ext3.tar, data.ext3.rar, nandriod.md5, system.ext3.tar. Do these look right?
