[Replicant] How to back up contacts, apps, f-droid DB, app data, files etc.?

[Josh Branning]

Hi,

I'm thinking of upgrading Replicant on my Nexus S, but I don't want to 
lose all my data in the process.

Is there a way to back up the necessary stuff so that upgrades are as 
painless as possible?

Alternatively, is there an update setting in Replicant that can be used 
to upgrade the device without losing these things.

Thanks,


Josh
