-# Checkpoints vs. Savepoints
+<a name="checkpoints-vs-savepoints"></a>
-## Overview
+# Checkpoints 与 Savepoints
-Conceptually, Flink's [savepoints]({{< ref "docs/ops/state/savepoints" >}})
are different from [checkpoints]({{< ref "docs/ops/state/checkpoints" >}})
-in a way that's analogous to how backups are different from recovery logs in
traditional database systems.
+<a name="overview"></a>
-The primary purpose of checkpoints is to provide a recovery mechanism in case
of unexpected job failures.
-A [checkpoint's lifecycle]({{< ref
"docs/dev/datastream/fault-tolerance/checkpointing" >}}) is managed by Flink,
-i.e. a checkpoint is created, owned, and released by Flink - without user
interaction.
-Because checkpoints are being triggered often, and are relied upon for failure
recovery, the two main design goals for the checkpoint implementation are
-i) being as lightweight to create and ii) being as fast to restore from as
possible.
-Optimizations towards those goals can exploit certain properties, e.g., that
the job code doesn't change between the execution attempts.
+## 概述
+
+从概念上讲，Flink 的 [savepoints]({{< ref "docs/ops/state/savepoints" >}}) 与
[checkpoints]({{< ref "docs/ops/state/checkpoints" >}})
的不同之处类似于传统数据库系统中的备份与恢复日志之间的差异。
+
+Checkpoints 的主要目的是为意外失败的作业提供恢复机制。
+[Checkpoint 的生命周期]({{< ref "docs/dev/datastream/fault-tolerance/checkpointing"
>}}) 由 Flink 管理，
+即 Flink 创建，管理和删除 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。 可能会利用某些特定的属性来达到这个，例如，
工作代码在执行尝试之间不会改变。
{{< hint info >}}
-- Checkpoints are automatically deleted if the application is terminated by
the user
-(except if checkpoints are explicitly configured to be retained).
-- Checkpoints are stored in state backend-specific (native) data format (may
be incremental depending on the specific backend).
+- 在用户终止作业后，会自动删除 Checkpoint（除非明确配置为保留的 Checkpoint）。
+- Checkpoint 以状态后端特定的（原生的）数据格式存储（根据特定后端可能是增量的）。
