I did try it while it was on beta, a good ics launcher

Edit:double post nova for ICS only so far, nova sometimes will get choppy though, nothing can beat the smoothness of tw laucher at the moment

Select backup all user apps, system apps are apps like phone.apk, calendar.apk, only back system apps if u need them for something, if not just backup user apps enuf

for me i will backup all...no3..but when restore, use "restore missing apps with data"
and yes, your data download 1GB no effect..still inside your internal storage.

I recommend what kazama said as well. Having system backed up as well can come in handy in certain cases.
Also, certain things like wifi access points can be manually restored after "restore missing apps with data".

Don't restore all system, especially after changing ROM. I had problems once when I tried that

I choose this:
3. Backup all user apps + system data
TB won't backup 1GB files, it just backup apps + settings( like game saved, app preference).

Btw, many of my files disappeared after flashed Turkbey v35. For example, Modern Combat remains 100+mb, Asphalt 6 remains few MB. I don't know what is going on, and it seems like I lost few Gigs disk space. I don't know what is going on with those lost gigs.
