Is there a good way to backup Core Data database with iCloud integration?

问题

Is there a good way to backup my sqlite information from iCloud in case CoreData sqlite + iCloud corrupts? Copying the .sqlite to another location? When the iCloud corrupts, reading the data out from the .sqlite to create a new iCloud sqlite?

回答1:

use migratePersistentStore API to create a copy of the store file in the devices /Documents directory where it will get backed up. See here for a more complete explanation and a sample app.
