You mean nand backup or the ROM zip file??
BTW here's a short review(may be experience is what I should say) on O2 for O1
No OC. This is just with the Stock ROM as it came. Will start OC'ing from today.
Overall, all the basic features like data, gps, music, camera, bluetooth, fm radio etc. as stated working fine. Though there are few problems which is noticeable. Like today when I turned on gps, it was working but gps icon was not there in the notification bar. After a reboot it's got fixed.
As the development thread already says, video using camera not working. Youtube has a green line.
Don't ask about tethering, as the feature is not there in this ROM.
Quadrant scores are really low, didn't even crossed 1000. Neocore gave 49fps as avg.
Other than these, battery life is really excellent. Now the screen-shots should speak themselves

Don't bother about the battery, it's yesterday's screenshot, after I flashed the ROM. Took it to post on FB. You can check the time

Around 11 hours 30 mins of (light) usage and only 7% with calls and sms. Isn't it excellent?? Wait..!! This is without WiFi / GPS / Data. Will post another before going to sleep..!!

NOTE : I'd suggest to flash GAPPS, as the one included in ROM only contains, Market, Gtalk, Gmail. Other than that you need to download everything else, like facebook, twitter, youtube, maps and even the file manager. Yes, there is no file manager by default.
In spare parts, I couldn't find sensors, so can't comment on that.
Hope I didn't missed anything, I'll check again and report back if by chance I've missed something.
