Zitan Chen 1569dc48f5 BackupEngine::VerifyBackup verifies checksum by default (#7014) ... Summary: A parameter `verify_with_checksum` is added to `BackupEngine::VerifyBackup`, which is true by default. So now `BackupEngine::VerifyBackup` verifies backup files with checksum AND file size by default. When `verify_with_checksum` is false, `BackupEngine::VerifyBackup` only compares file sizes to verify backup files. Also add a test for the case when corruption does not change the file size.
