找出备份和恢复系统是否正常工作是不是只知道长的备份和恢复如何采取更复杂;同意一套核心必不可少的指标的关键是正确判断你的系统，以确定它是否成功，或者需要重新设计。

这里有五个指标，每一个企业都应该收集，以确保他们的系统满足需要业务

存储容量和使用

让我们先从一个非常基本的指标：请问您的备份系统有足够的存储容量，以满足当前和未来的备份和恢复需求？无论你是在谈论一个磁带库或存储阵列，存储系统的容量都是有限的，并且需要您在使用一段时间什么呢个监测什么能力和。 阅读这篇文章完全请点击此处 //m.banksfrench.com/article/3534500/5-metrics-you-need-to-know-about-your-backup-and-recovery-system.html 2020年3月2日星期一21:00:00 -0800 w·柯蒂斯普雷斯顿 w·柯蒂斯普雷斯顿

Backup and disaster recovery systems often do not get the respect or budget that they deserve, and despite its potentially dire dangers, the coronavirus COVID-19 could actually help change that.

Most things you would do to prepare for the disease are no different than what you should normally be doing, but concerns about the virus might help accelerate existing plans or to reconsider some long-standing policies.

Prepare for a mobile workforce

Most employees are already very mobile and do most of their work on laptops and mobile devices, so it's perfectly reasonable to think that your company is prepared for a mobile workforce. However, just because your employees can work from virtually anywhere doesn't necessarily mean that you are prepared for all or most of them to be mobile all of the time. Don’t underestimate the degree to which face-to-face interaction is at the core of how you do business.

由于我们存储数据的增加额，什么是被称为3-2-1规则经常被遗忘的基本概念。这是一个问题，因为3-2-1规则是容易对设计数据保护的最基础的概念之一。理解为什么创建规则是很重要的，而且它是如何目前被解释在一个日益无带化的世界。

什么是3-2-1规则备份？

3-2-1规则说应该有至少三个副本或存储在两段不同的媒体，其中之一就是异地数据的版本。让我们来看看这三个要素以及它的地址。 <抛开类=“fakesidebar”> [通过注册网络世界通讯获取定期的见解]

• 3级的副本或版本：具有足球竞猜app软件至少三个不同版本的数据，随着时间的推移，确保不同时期，你可以从影响多个版本的事故中恢复过来。任何一个优秀的备份系统会有很多超过三份
• 2个不同的媒体：你不应该有你的数据的两个副本在同一介质上。举个例子，苹果的Time Machine。您可以使用光盘实用程序到你的硬盘分成两个虚拟卷，然后使用Time Machine备份第一卷的“第二”卷欺骗它。如果主驱动器发生故障，备份也将失败。 This is why you always have the backup on different media than the original.
• 1 backup off-site: A speaker at a conference once said he didn't like tapes because he put them in a box on top of a server, and they melted when the server caught fire. The problem wasn't tape; the problem was he put his backups on top of his server. Your backup copies, or at least one version of them, should be stored in a different physical location than the thing you are backing up.

Mind the air gap

An air gap is a way of securing a copy of data by placing it on a machine on a network that is physically separate from the data it is backing up. It literally means there is a gap of air between the primary and the backup. This air gap accomplishes more than simple disaster recovery; it is also very useful for protecting against hackers.

Yes, your container infrastructure needs some type of backup.  Kubernetes and Docker will not magically build themselves after a disaster. As discussed in a separate article, you don’t need to back up the running state of each container, but you will need to back up the configuration used to run and manage your containers.

Here’s a quick reminder of what you’ll need to back up.

Configuration and desired-state information

• The Dockerfiles used to build your images and all versions of those files
• The images created from the Dockerfile and used to run each container
• Kubernetes etcd & other - K8s databases that info on cluster state
• Deployments - YAML files describing each deployment

Persistent data created or changed by containers

• Persistent volumes
• Databases

Dockerfiles

Docker containers are run from images, and images are built from Dockerfiles. A proper Docker configuration would first use some kind of repository such as GitHub as a version-control system for all Dockerfiles. Do not create ad hoc containers using ad hoc images built from ad hoc Dockerfiles. All Dockerfiles should be stored in a repository that allows you to pull historical versions of that Dockerfile should there be a problem with the current build.

Containers are breaking backups around the world, but there are steps you can take to make sure that the most critical parts of your container infrastructure are protected against the worst things that can happen to your data center.

At first glance it may seem that containers don’t need to be backed up, but on closer inspection, it does make sense in order to protect against catastrophic events and for other, less disastrous eventualities.

Container basics

Containers are another type of virtualization, and Docker is the most popular container platform. Containers are a specialized environment in which you can run a particular application. One way to think of them is like lightweight virtual machines. Where each VM in a hypervisor server contains an entire copy of an operating system, containers share the underlying operating system, and each of them contains only the required libraries needed by the application that will run in that container. As a result, many containers on a single node (a physical or virtual machine running an OS and the container runtime environment) take up far fewer resources than the same number of VMs.

The failure to back up data that is stored in a cloud block-storage service can be lost forever if not properly backed up. This article explains how object storage works very differently from block storage and how it offers better built-in protections.

What is Object Storage?

Each cloud vendor offers an object storage service, and they include Amazon's Simple Storage Service (S3), Azure’s Blob Store, and Google’s Cloud Storage.

Think of object storage systems like a file system with no hierarchical structure of directories and subdirectories. Where a file system uses a combination of a directory structure and file name to identify and locate a file, every object stored in an object storage system gets a unique identifier (UID) based on its content.

Deduplication is arguably the biggest advancement in backup technology in the last two decades.  It is single-handedly responsible for enabling the shift from tape to disk for the bulk of backup data, and its popularity only increases with each passing day.  Understanding the different kinds of deduplication, also known as dedupe, is important for any person looking at backup technology.

What is data deduplication?

Dedupe is the identification and elimination of duplicate blocks within a dataset. It is similar to compression, which only identifies redundant blocks in a single file. Deduplication can find redundant blocks of data between files from different directories, different data types, even different servers in different locations.
