   NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);

   NSString* docPath = [documentPaths objectAtIndex:0];

    [selfaddSkipBackupAttributeToItemAtURL:docPath];

}

/**

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSString *)filePathString

{

   NSURL* URL = [NSURLfileURLWithPath:filePathString];

   assert([[NSFileManagerdefaultManager] fileExistsAtPath: [URLpath]]);

    

   NSError *error = nil;

   BOOL success = [URL setResourceValue: [NSNumbernumberWithBool: YES]

                                 forKey: NSURLIsExcludedFromBackupKeyerror: &error];

   if(!success){

       NSLog(@"Error excluding %@ from backup %@", [URLlastPathComponent], error);

    }

}

success;
