+## 什么是 Savepoint ? Savepoint 与 Checkpoint 有什么不同?
-A Savepoint is a consistent image of the execution state of a streaming job, created via
Flink's [checkpointing mechanism]({{ site.baseurl }}/internals/stream_checkpointing.html).
You can use Savepoints to stop-and-resume, fork,
-or update your Flink jobs. Savepoints consist of two parts: a directory with (typically large)
binary files on stable storage (e.g. HDFS, S3, ...) and a (relatively small) meta data file.
The files on stable storage represent the net data of the job's execution state
-image. The meta data file of a Savepoint contains (primarily) pointers to all files on stable
storage that are part of the Savepoint, in form of absolute paths.
+Savepoint 是依据 Flink [检查点机制]({{ site.baseurl }}/internals/stream_checkpointing.html)所创建的流作业执行状态的一致镜像。
您可以使用 Savepoint 来停止并恢复,fork,或更新您的 Flink 工作。 Savepoint
由两部分组成:具有稳定存储(例如 HDFS,S3,...)上的(通常是大的)二进制文件的目录和(相对较小的)元数据文件。
稳定存储上的文件表示作业执行状态的净数据图片。 Savepoint 的元数据文件以(绝对路径)的形式包含(主要)指向作为
Savepoint 一部分的稳定存储上的所有文件的指针。

-<strong>Attention:</strong> In order to allow upgrades between programs and Flink
versions, it is important to check out the following section about <a href="#assigning-operator-ids">assigning
IDs to your operators</a>.
+<strong>注意:</strong> 为了允许程序和 Flink 版本之间的升级,请务必查看以下有关<a
href="#assigning-operator-ids">分配算子 ID </a>的部分 。
+从概念上讲,Flink 的 Savepoint 与 Checkpoint 的不同之处在于备份与传统数据库系统中的恢复日志不同。

-->从概念上讲, Flink 的 Savepoint 与 Checkpoint 的不同之处类似于传统数据库中的备份与恢复日志之间的差异。
   2. 检查点的主要目的是提供恢复机制,以防万一出乎意料的失业 -->
