你们中的一些人可能听说过Mac OS(Mac OS)中的内置备份应用程序，称为Time Machine。Mac用户喜欢相信它是完美的备份解决方案。这种观点可能过于乐观，但它确实包含了一些事实。Time Machine提供了一个非常好的备份策略。
它的工作原理如下：每个备份副本都在外部或网络驱动器上创建为名称与备份日期匹配的文件夹。每个文件夹都包含创建备份副本时的数据快照，并完整保留文件结构。默认情况下，Time Machine保留过去 24 小时的每小时备份、上个月的每日备份以及其余时间的每周备份。例如，您可以轻松取消早上在演示文稿中所做的任何不需要的更改，或者打开一个一周前的项目版本。
为此，您不必对档案执行任何复杂的操作、启动一些特殊的应用程序等等。只需(Simply)使用任何文件管理器查找包含所需日期的备份副本的文件夹。还有更多。
为了有效地使用磁盘空间，使用了以下方法：实际上只为上次备份后发生变化的文件创建备份副本；对于任何未修改的文件，都会创建硬链接，让您可以从不同的文件夹中引用同一个文件，并且占用很少的磁盘空间。因此，Time Machine 的备份不仅易于使用，还可以节省您的磁盘空间。
@MAX SyncUp 评论
奇怪的是，一直很难在Windows 8中使用类似的备份策略。但是现在您也可以拥有它，这要归功于最近发布的@MAX SyncUp新版本。除此之外，这个出色的应用程序可以进行类似 Time Machine 的备份。
@MAX Sync Up is a free backup software that lets you create Time Machine like backups in Windows, sync Computers over the Internet, sync Files and Folders, Back Up Data to Google Drive, and more!
在Windows(Windows)中创建类似 Time Machine 的(Time Machine-like)备份
配置简单：安装@MAX SyncUp后，启动新建配置文件向导(New Profile Wizard)，选择需要备份数据的文件夹，指定存储类型为未压缩文件，指定备份的存储深度，指定创建路径备份副本等。对于这种类型的备份，您可以在应用程序的网站上找到分步说明，包括视频。
需要注意的是，与Time Machine不同，@ MAX SyncUp目前不允许您配置在磁盘空间不足的情况下自动删除旧备份副本。您必须明确指定保留备份副本的时间段。（磁盘空间不足会产生错误消息。）一方面是限制；另一方面是限制。另一方面，这是确保达到所需存储深度的唯一方法。
通过 Internet 同步计算机
如果您像大多数计算机用户一样，有时您需要确保您在一台 PC 上更改的文件在其他地方的其他计算机上更新。也许您需要确保您的家庭办公室台式机和您旅行时随身携带的笔记本电脑具有相同的文件，或者在有人对您的演示文稿进行更改后更新每个人，从而使团队中的每个人都保持在一个页面上。很多时候，您需要确保您的某些文件由多个系统共享。
有很多实用程序可以同步同一网络上的计算机。但是，当计算机相隔很远时，包括专业人士在内的大多数用户都会使用Dropbox或Google Drive等云存储服务。云(Cloud)服务将您的数据存储在数据中心的计算机上。云(Cloud)服务是可靠的，因为它们在世界各地的数据中心维护您的数据的多个副本。但是，将数据保存在“云中”存在一些主要问题。
- 云(Cloud)服务提供商必须为他们的计算机付费，因此如果您存储超过几 GB 的数据，您就必须向他们付费。
- 您只能通过服务提供商的网络访问您的数据，即使是最大的提供商有时也会因高需求而减慢速度。
- (Big)对于想要访问大量其他人信息的人来说，大数据中心是诱人的目标。
您可以使用@MAX SyncUp 来避免所有这些问题，这是一个强大的同步和备份实用程序，可让您直接相互同步计算机。当您将计算机直接相互同步时，您就切断了云服务中间人。您的数据只会发送到您发送的地方。没有其他人存储您的数据，因此您不必担心其他人是否保护数据安全，也不必处理费用或存储限制。
使用@Max SyncUp 很简单，您不需要任何有关计算机或网络的专业知识来设置它。
- 首先，在您要同步的所有计算机上安装@MAX SyncUp。
- 其次，选择一台计算机作为服务器。每当其他计算机需要同步并且需要具有公共 IP 或动态 IP 地址时，服务器都需要打开。几乎(Almost)所有家用 PC 和许多办公 PC 都将满足这些要求。向导将指导您完成该过程的每个步骤。
- 第三(Third)，将其他计算机设置为@Max SyncUp 服务器的客户端。另一个向导将允许您选择要同步的文件夹、指定同步计划和首选项以及自定义您的配置文件。
最常见的设置仅在文件更改时同步文件。这使您可以在几分钟内更新世界各地计算机上的文件。它还通过仅在需要更改文件时同步文件来节省资源，同时减少网络和计算机的负载。
@Max SyncUp甚至有一个独特的算法，可以识别文件中已更改的部分并仅传输文件的一部分。
这意味着，如果您对巨大的电子表格或演示文稿进行一些小的更改，您只需同步文件的这些部分。这大大减少了同步大文件所需的时间，只需进行少量更改。该算法已经在RSync中使用，这是一个(RSync)UNIX系统的控制台应用程序，但在 @MAX SyncUp 中，他们通过更新和用户友好的图形界面对其进行了改进。
@ MAX SyncUp还加密和压缩传输的数据。AES加密可在服务器和客户端之间传输的几秒钟内保护您的数据。
压缩通过减少传输的数据量使同步过程更快。@ MAX SyncUp是让您的数据在不同地方的多台计算机上保持最新的最佳方式……但它的作用更多。
@ MAX SyncUp是一个功能齐全的备份实用程序，具有所有标准功能，还有一些：
- 支持在FTP、SFTP或WebDAV服务器上备份。
- 支持谷歌云端硬盘。
- 创建完整和增量档案。
- 支持数据压缩和加密。
- 保留文件和文件夹权限。
- 作为 Windows 服务运行。
- 支持卷影复制服务。
- 恢复单个文件或整个系统。
- 有效利用系统资源。
- 方便的用户界面。
这些只是您通过@Max SyncUp 获得的部分功能。该程序可免费用于个人非商业用途(free for personal non-commercial use)。免费版本虽然有限制，即。每个配置文件 1 个备份或同步(1 backup or sync per profile)，对于大多数普通用户来说就足够了，因为配置文件可以包含无限数量的文件。免费版本中提供了所有其他功能。

MAX SyncUp: Create Backups, Sync computers over the Internet
Some of you may have heard about the built-in backup application in Mac OS, called the Time Machine. Mac users like to believe it’s the perfect backup solution. This opinion might be too optimistic, but it does contain a grain of truth. Time Machine provides a really good backup strategy.
Here’s how it works: Each backup copy is created on an external or network drive as a folder whose name matches the date of the backup. Each folder contains a snapshot of the data at the moment of creating the backup copy, with full preservation of the file structure. By default, Time Machine keeps hourly backups for the last 24 hours, daily backups for the last month, and weekly backups for the rest. For example, you can easily cancel any unwanted changes you made in your presentation in the morning, or open a week-old version of a project.
To do that, you don’t have to do any complicated actions with archives, launch some special applications, and so on. Simply use any file manager to find the folder containing the backup copy for the needed date. There’s more to come.
To use the disk space efficiently, the following method is used: Backup copies are actually created only for those files that have changed after the previous backup; for any unmodified files, hard links are created, which let you refer to the same file from different folders and occupy very little disk space. As a result, Time Machine’s backups are not only easy to use but also save your disk space.
@MAX SyncUp review
Curiously enough, it has always been hard to use a similar backup strategy in Windows 8. But now you can have it, too, thanks to the recent release of a new version of @MAX SyncUp. Among other things, this outstanding application can make Time Machine-like backups.
@MAX Sync Up is a free backup software that lets you create Time Machine like backups in Windows, sync Computers over the Internet, sync Files and Folders, Back Up Data to Google Drive, and more!
Create Time Machine-like backups in Windows
It’s easy to configure it: After installing @MAX SyncUp, launch the New Profile Wizard, select folders with the data that should be backed up, specify the type of storage as uncompressed files, specify the storage depth for backups, specify the path for creating backup copies, and so on. For this type of backup, you can find step-by-step instructions, including a video, on the application’s website.
It should be noted that, unlike Time Machine, @MAX SyncUp currently doesn’t let you configure automatic removal of old backup copies in case of disk space shortage. You have to explicitly specify the period of time to keep the backup copies. (A disk space shortage will produce an error message.) On the one hand, it is a limitation; on the other hand, it’s the only way to make sure that the required storage depth is achieved.
Sync Computers over the Internet
If you’re like most computer users, there are times when you will need to make sure that a file you change on one PC is updated on other machines somewhere else. Maybe you need to make sure that your home office desktop and the laptop you travel with have the same files, or keep everyone on your team on one page by updating everyone after someone makes a change to your presentation. There are many times when you need to make sure that some of your files are shared by multiple systems.
There are plenty of utilities that will sync computers on the same network. However, when computers are separated by long distances, most users, including professionals, use cloud storage services like Dropbox or Google Drive. Cloud services store your data on computers in a data center. Cloud services are reliable because they maintain multiple copies of your data in data centers around the world. However, there are some major problems with keeping your data “in the cloud.”
- Cloud service providers have to pay for their computers, and so you have to pay them if you store more than a few gigabytes of data.
- You can only reach your data through the service provider’s network, and even the biggest providers sometimes get slowed down by high demand.
- Big data centers are tempting targets for people who want to access a lot of other people’s information.
You can avoid all these problems by using @MAX SyncUp, a powerful sync and backup utility that allows you to sync computers directly to each other. When you sync computers straight to each other, you cut out the cloud service middleman. Your data only goes where you send it. No one else stores your data, so you don’t have to worry about whether other people are keeping it safe, and you don’t have to deal with fees or limits on your storage.
Using @Max SyncUp is easy, and you don’t need any specialized knowledge of computers or networks to set it up.
- First, install @MAX SyncUp on all the computers you want to sync.
- Second, pick a computer to be the server. The server needs to be on whenever other computers need to sync and it needs to have either a public IP or a dynamic IP address. Almost all home PCs and many office PCs will meet these requirements. A wizard will guide you through each step of the process.
- Third, set up other computers as clients of the @Max SyncUp server. Another wizard will let you select the folders to sync, specify your sync schedule and preferences, and customize your profile.
The most common setting only syncs files when they are changed. This lets you update files on computers all over the world in a few minutes. It also saves resources by only syncing files when they need to be changed while reducing the load on your network and your computers.
@Max SyncUp even has a unique algorithm that identifies the parts of a file that have changed and transfers only part of a file.
This means that if you make a couple of small changes to a huge spreadsheet or presentation, you will only have to sync those sections of the file. This drastically reduces the time it takes to sync large files with only a few changes. This algorithm has already been used in RSync, a console app for UNIX systems, but in @MAX SyncUp they have improved it with an updated and user-friendly graphical interface.
@MAX SyncUp also encrypts and compresses transferred data. AES encryption keeps your data protected during the seconds it takes to be transferred between the server and the client.
Compression makes the sync process even faster by reducing the amount of data transferred. @MAX SyncUp is the best way to keep your data current on many computers in different places…but it does even more.
@MAX SyncUp is a fully functional backup utility with all the standard features and then some:
- Supports backup on FTP, SFTP, or WebDAV servers.
- Supports Google Drive.
- Creates full and incremental archives.
- Supports data compression and encryption.
- Preserves file and folder permissions.
- Runs as a Windows service.
- Supports Shadow Copy Service.
- Restores single files or a whole system.
- Efficient use of system resources.
- Convenient user interface.
These are only some of the features you get with @Max SyncUp. The program is free for personal non-commercial use. The free version though having the restriction viz. 1 backup or sync per profile, is enough for most of the regular users, because the profile can include an unlimited number of files. All of the other functions are available in the free version.
You can download it and get more information about this backup software on its home page.
