iOS doesn't have a user-accessible file system because it's trying (as you might know) a bet to move to a paradigm where the filesystem is not exposed to the user. Not saying is correct or not, but it is a precise design choice. Regardless, I had my iPhone jailbroken for 2 years, with full SSH root access and never used it, and I would have never used it to backup since there was a much more stable, officially tested and supported way to implement it; the least thing I wanted is to lose my data because I wanted to be smart and implemented an in-house untested solution. This is why I'm genuinely curious whether the shell on a N900 empowers to do things that aren't reasonably found on a consumer-level feature.
