玩工程机，尤其是那些没有正式发布的工程机的时候，完整系统备份非常有必要。
因为你永远也不知道你有什么奇怪的想法会把系统玩崩，如果没做备份就永远恢复不回去了。
我这边不论是 Windows Phone 还是 Android 系统的工程机，全部会做好妥当的备份归档，即便手机不在我手上或是被出售了，它们也不会被删除。
说不定，你的工程机备份会成为解决世界级难题的钥匙。

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
