Backup Core Data with Dropbox

[phonepro]

Fora while, I have been trying to come up with a robust iPhone backup solution that is easy for users. I was intrigued about the Dropbox API as a possibility to build such a user-friendly backup system. Anyway after a lot of work I was able to get it to work! So far I've been getting very positive feedback from users, and I feel that it may be useful to other developers to take a similar technique. The latest update to my app, FlashCards++, was just released with built-in Dropbox support, enabling users to back up their core data store (sqlite file) onto dropbox & restore the sqlite file directly from dropbox.

I'd be happy to answer any questions about how others can incorporate similar functionality into their app, also I'm open to suggestions on how I might better incorporate Dropbox support and backup/restore generally. What do you think?

Jason,

I'm also trying to back up the data in my app's (Sewing Kit) core data db to DropBox. I'm really interested in how you got this done? Did you copy the whole core data file to DropBox? Did you cycle through the data and export it first?

I'm trying to get the data out of the DB in case in a future update I change the database, and folks have trouble with it (happened to about 5% of my users last time)... I want to give them the ability to get the data out, and back into the app - independent of the Core Data structures...

Any insight would be fantastic!

Thanks,

Mike.

I am able to upload/download sqlite file. But when I upload, my app crashes. Ay ideas or do you have code to show how to do this successfully?

How exactly does it crash? What does the crash log say, and can you show the relevant code where it crashes?
