只有在您丢失浏览历史记录后，您才会意识到您对它的依赖程度。您将浪费数小时追踪您经常访问的所有重要网站，更不用说您再也找不到的网站了。

丢失您的Google Chrome历史记录非常容易。计算机崩溃、意外点击、Windows更新出错 - 您的Chrome历史记录可能被删除的原因有很多。

防止这种情况发生的唯一方法是备份您的浏览器历史记录。因此，这里有所有可以备份Google Chrome历史记录的方法。

打开谷歌浏览器同步

我们每天都使用多种计算设备。您的手机、笔记本电脑、工作计算机——所有这些都可以访问互联网，并且可能链接到同一个Google帐户。这允许您使用一个漂亮的小功能，称为同步。

同步^(Sync)可实现无缝浏览。您可以从上下班途中在手机上查找某些信息切换到工作中破旧的旧 PC，而无需重新开始。启用同步后，您的所有个人数据（如书签和搜索历史记录）都会复制到您也登录Google帐户的其他设备。

因此，确保您永远不会丢失Chrome历史记录的最简单方法是打开同步功能^{(turn on sync)}。这样，即使您的其中一台设备出现故障（或者您不小心卸载了Chrome），您也可以再次登录以恢复所有浏览器历史记录。

以下是在Google Chrome^{(Google Chrome)}上启用同步的方法：

1. 打开Google Chrome并登录您的Google 帐户^{(Google Account)}。

1. 在新选项卡中，单击右上角的三个点以显示菜单。点击^(Click)设置^(Settings.)。

1. 您看到的第一个选项是打开同步^{(Turn on sync)}按钮。点击它。

1. 您将被要求再次确认您的选择。只需^(Just)点击  是的，我在^{(Yes, I’m in )}，你就完成了。

备份历史文件

如果您不想将保护您的Chrome历史记录的工作交给Google，您可以创建自己的备份。如果您不小心从Google^(Google)帐户中清除了数据，这也会派上用场，因为这会擦除每台设备上的所有内容。此时恢复数据的唯一方法是使用本地备份。

这样做很简单。Google Chrome会自动将您的浏览历史记录存储在您计算机上的MySQL数据库文件中。您只需将该文件复制到USB驱动器（或Dropbox帐户）。当您需要恢复它时，只需将该文件再次复制到其主目录，替换现有数据库即可。

以下是如何去做：

1. ^{(Open File Explorer)}在您的计算机上打开文件资源管理器，然后在地址^(Address)栏中输入C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default（其中Username是您的用户名） 。

1. 在这个文件夹中有一个名为“历史”的文件。这是我们正在寻找的数据库文件。将其复制并粘贴到另一个目录或驱动器作为备份。建议定期重复此操作，以便您可以从一系列备份中恢复。
2. 当您的Chrome历史记录丢失并且您需要恢复它时，请将较旧的历史记录文件复制到该文件夹​​中。如果出现提示，请选择替换。^(Replace)下次您运行Google Chrome时，您的搜索历史记录将被恢复。

设置文件历史记录

一遍又一遍地手动备份同一个文件可能会很痛苦。没有任何方法可以在Windows中自动创建特定文件或文件夹的备份吗？

实际上，有一个。它称为文件历史记录^{(File History)}。

也称为以前的版本，此功能允许您创建重要文件夹的定期备份，并在需要时将它们恢复到以前的版本。如果您可以为您的Google文件夹^(Google)设置文件历史记录，您将能够顺利地将^{(set up File History)}历史记录^(History)文件回滚到之前的任何时间点。

以下是在您的计算机上设置文件历史记录的步骤：^{(File History)}

1. 首先打开Windows 设置^{(Windows Settings)}。您可以在“开始^(Start)”菜单中找到该图标。

1. 设置窗口打开后，在底部查找更新和安全。^{(Update & Security)}点击它。

1. 在更新和安全^{(Update & Security)}中，选择备份^(Backup)选项卡。文件历史记录^{(File History)}是右侧的第一个选项。

1. 现在您需要添加一个外部驱动器来存储您的备份数据。建议使用外部硬盘^(HDD)，因为定期备份会占用相当多的空间。连接您的驱动器并使用添加驱动器^{(Add a drive)}按钮将其选中。

1. 选择驱动器会自动激活File History，正如您从切换中看到的那样。但是如何控制备份中包含哪些文件夹？为此，请选择更多选项^{(More options)}。

1. 在备份选项中，您可以自定义流程的各个方面。您可以选择备份的频率，还可以决定备份的保留时间。以下^(Below)是将要备份的所有文件夹的列表。您可以删除任何文件夹并添加您自己的任何文件夹。只需^(Just)确保用户^(Users)文件夹或至少Google文件夹在列表中。

将历史^(History)恢复到以前的版本

即使在您的计算机上启用了文件历史记录^{(File History)}，您如何将Chrome的历史记录^(History)文件恢复到以前的版本？

以下是这样做的步骤：

1. 导航到C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default，其中 Username 将替换为您自己的用户名。您只需在文件资源管理器的地址^(Address)栏中键入此地址，然后按Enter即可直接前往。

1. 右键单击^{(Right-click)}History文件^(History)并选择Properties。

1. 切换到以前的版本^(Versions)选项卡。如果您的计算机上启用了文件历史记录^{(File History)}（并且连接了外部驱动器），它会按各自的日期显示文件的所有备份版本。选择您要恢复的版本，然后选择恢复^(Restore)。

如何查看丢失的 Google Chrome 历史记录^{(Lost Google Chrome History)}

我们已经看到了多种备份Google Chrome历史记录的方法。但是，如果您不使用它们中的任何一个怎么办？还有什么方法可以查看丢失的浏览历史记录吗？

是的。如果您已删除本地历史记录^(History)文件并且未激活同步，您仍然可以查看您的浏览历史记录。这是因为Google 会记录您^{(Google keeps a log of your activity)}在其应用程序（包括Chrome ）上的活动。此活动包括搜索词和访问的网站，本质上是您浏览历史的副本。

以下是查看您的Google帐户活动的步骤：

1. 打开 Chrome 并转到我的活动^{(My Activity)}。

1. 使用您的Google^(Google)帐户登录以访问“我的活动”^{(My Activity)}仪表板。

1. 在此仪表板上，您可以查看所有 Web 和应用程序活动的记录。默认情况下，它也包括您的 Android 设备上的活动。

1. 要仅查看您的浏览器历史记录，请选择按日期和产品筛选^{(Filter by date & product)}选项。在弹出窗口中，选择Chrome并选择Apply。活动列表将更新为仅显示您的搜索历史记录。

备份您的Google Chrome 历史记录^{(Google Chrome History)}

有多种方法可以备份您的Google Chrome历史记录，从 Google 的内置功能到您端的外部备份。

当然，最简单的方法是依靠Google同步为您完成繁重的工作。虽然这很好用，但如果你不小心清除了Chrome上的所有数据，它就会变得毫无用处。

这就是本地备份派上用场的地方。无论您使用文件历史记录^(History)还是只是复制粘贴MySQL数据库，您都可以使用该备份将您的浏览历史记录轻松恢复到其旧状态。

如果一切都失败了，您可以随时使用Google Account Activity获取您在Chrome上的网络活动记录。

How to Backup Google Chrome History

It is only after you lose your browsing history that you realize how mυch you relied on it. You’ll waste hours and hоυrs tracking down all the important websites you frequently visit, to say nothing of thе sites you never find again.

And losing your Google Chrome history is surprisingly easy. A computer crash, an accidental click, a Windows update gone wrong – there are many reasons why your Chrome history might get deleted.

The only way to prevent this from happening is to back up your browser history. So here are all the ways you can backup your Google Chrome history.

Turn on Google Chrome Sync

We all use multiple computing devices every day. Your phone, your laptop, your work computer – all of these can access the internet and are probably linked to the same Google account. This allows you to use a nifty little feature called sync.

Sync enables seamless browsing. You can switch from looking up some information on your mobile during your commute to the battered old PC at work without having to start afresh. With sync enabled, all of your personal data like your bookmarks and search history is copied over to your other devices where you’re also logged into your Google account.

Therefore, the easiest way to ensure that you never lose your Chrome history is to turn on sync. That way even if one of your devices malfunctions (or you accidentally uninstall Chrome), you can just sign in again to get all of your browser history back.

Here is how you enable sync on Google Chrome:

1. Open Google Chrome and sign in to your Google Account.

1. In a new tab, click on the three-dots on the top right to bring down the menu. Click on Settings.

1. The very first option you see is the button to Turn on sync. Click on it.

1. You will be asked to confirm your choice again. Just hit  Yes, I’m in and you are done.

Backup the History File

If you don’t want to leave the job of securing your Chrome history to the mercies of Google, you can create backups of your own. This also comes in handy if you accidentally clear your data from your Google account, since that wipes everything from every device. The only way to get your data back at that point is by using a local backup.

Doing so is simple. Google Chrome automatically stores your browsing history in a MySQL database file on your computer. You just need to copy that file to a USB drive (or a Dropbox account). When you need to restore it, just copy that file to its home directory again, replacing the existing database.

Here is how to go about it:

1. Open File Explorer on your computer and enter C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default (where Username is your username) in the Address bar.

1. In this folder is a file named “History”. This is the database file we are looking for. Copy it and paste it into another directory or drive as a backup. It is recommended to repeat this periodically so that you have a range of backups to restore from.
2. When your Chrome history goes missing and you need to recover it, copy an older History file into this very folder. Choose to Replace if you are prompted. The next time you run Google Chrome, your search history will be restored.

Setting Up File History

Manually backing up the same file over and over again can be a pain. Isn’t there any method to automatically create backups of a specific file or folder in Windows?

Actually, there is one. It is called File History.

Also known as Previous Versions, this feature allows you to create periodic backups of your important folders and restore them to their previous versions if needed. If you can set up File History for your Google folder, you will be able to roll back the History file to any previous point of time without a hitch.

Here are the steps for setting up File History on your computer:

1. Begin by opening Windows Settings. You can find the icon in the Start menu.

1. Once the settings window opens up, look for Update & Security at the bottom. Click on it.

1. In Update & Security, select the Backup tab. File History is the first option on the right.

1. Now you need to add an external drive to store your backup data. An external HDD is recommended, as the periodic backups can take up quite a bit of space. Connect your drive and use the Add a drive button to select it.

1. Choosing a drive automatically activates File History, as you can see from the toggle. But how can you control which folders are included in the backup? For that, select More options.

1. In the backup options, you can customize every aspect of the process. You can choose the frequency of the backups, and also decide how long the backups are kept. Below is the list of all the folders that will be backed up. You can remove any folders and add any folders of your own. Just make sure that the Users folder or at least the Google folder is in the list.

Restoring History to a Previous Version

Even with File History enabled on your computer, how exactly do you restore your Chrome’s History file to a previous version?

Here are the steps for doing so:

1. Navigate to C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default, where Username is to be replaced with your own username. You can just type this address in File Explorer’s Address bar and press Enter to go there directly.

1. Right-click on the History file and select Properties.

1. Switch to the Previous Versions tab. If File History is enabled on your computer (and the external drive is connected), it shows all the backed-up versions of the file by their respective dates. Select the version you want to recover and select Restore.

How to View Your Lost Google Chrome History

We have seen multiple ways to back up your Google Chrome history. But what if you didn’t use any of them? Is there still any method for viewing your lost browsing history?

Yes. If you’ve deleted your local History file and not activated sync you can still view your browsing history. This is because Google keeps a log of your activity on its apps, including Chrome. This activity includes search terms and websites visited, essentially functioning as a duplicate of your browsing history.

Here are the steps for viewing your Google account activity:

1. Open Chrome and go to My Activity.

1. Sign in with your Google account to access the My Activity dashboard.

1. On this dashboard, you can see a record of all of your web and app activity. By default, it includes the activity on your Android devices too.

1. To see just your browser history,select the Filter by date & product option. In the popup window, select Chrome and select Apply. The activity list will update to display only your search history.

Backing Up Your Google Chrome History

There are a variety of methods for backing up your Google Chrome history, from Google’s built-in functions to external backups on your end.

The easiest way, of course, is to rely on Google sync to do the hard work for you. While this works pretty well, it is rendered useless if you accidentally cleared all of your data on Chrome.

That is where local backups come in handy. Whether you use File History or just copy-paste the MySQL database, you can use that backup to restore your browsing history to its old state quite easily.

And in case all else fails, you can always use Google Account Activity to obtain a record of your web activity on Chrome.
