-## What is a Savepoint? How is a Savepoint different from a Checkpoint?
+## 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 [checkpointing 机制]({{ site.baseurl
}}/internals/stream_checkpointing.html)所创建的流作业执行状态的一致镜像。 你可以使用 Savepoint 进行
Flink 作业的停止与重启、fork或者更新。 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
--> 稳定存储（例如 HDFS、S3等）上包含二进制文件的目录（通常很大）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数据镜像。
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 的不同之处类似于传统数据库中的备份与恢复日志之间的差异。
Checkpoint的主要目的是为意外失败的作为提供恢复机制。 Checkpoint 的生命周期由Flink管理，即 Flink 创建，拥有和发布
Checkpoint - 无需用户交互。 作为一种恢复和定期触发的方法，Checkpoint 实现有两个设计目标：i）轻量级创建和 ii）尽可能快地恢复。
针对这些目标的优化可以利用某些属性，例如， 工作代码在执行尝试之间不会改变。 在用户终止作业后，通常会删除 Checkpoint（除非明确配置为保留的
Checkpoint）。
