You can call the following function to pass the path of your "map.sqlite" as NSURL:

NSURL *url = [NSURL fileURLWithPath:yourSQLitePath];
[self addSkipBackupAttributeToItemAtURL:url];
The function is provided in Apple as:

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);

    NSError *error = nil;
    BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
                              forKey: NSURLIsExcludedFromBackupKey error: &error];
    if(!success){
        NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
    }
    return success;
}
