The big issue I see right now with using a zip file is when it comes to incremental backups, I will have no way to edit the existing zip file to append new data. The Android ZipFile class does not support this, and I haven't found an open source library for Android that will let me modify an existing zip file. This would make my idea for incremental backups a lot more messy, because I would need to implement a model where I chain together incremental backup files, instead of just being able to write the incremental backup to the end of the existing backup file. If you have other ideas on this issue, or suggestions for an open source library to look at, let me know.
