How to Restore Databases with 2023 R2: A Step-by-Step Guide
A database is one of the most important assets of a business. It contns all of the information that is necessary for the day-to-day operations of the organization. However, database corruption or loss can occur due to various reasons like hardware flure, human error, or a malicious attack. In these situations, the ability to restore the database quickly is vital for minimizing the downtime and avoiding any losses.
Microsoft SQL Server is one of the most popular database management systems in the world. It is widely used for managing and organizing data in organizations of all sizes. SQL Server comes with many tools and features that help in database management, including the ability to restore a database. In this article, we will discuss how to restore databases with 2023 R2, a version of Windows Server.
Before proceeding with the restoration process, it is important to have a backup of the database. You can use SQL Server Management Studio to take a backup of the database. The backup file can be stored locally or on a network drive, depending on your requirements.
Step 1: Launch SQL Server Management Studio
The first step is to open SQL Server Management Studio on the server where the database is located. You can find it by searching for “SQL Server Management Studio” in the Start menu.
Step 2: Connect to the Server
Once SQL Server Management Studio is open, you need to connect to the server where the database is located. Enter the server name, username, and password when prompted.
Step 3: Select the Database to Restore
In the Object Explorer, expand the Databases folder and select the database that you want to restore. Right-click on the database and select “Tasks” from the context menu. Then, click on “Restore” and “Database.”
Step 4: Choose the Backup File
In the “Restore Database” dialog box, select “From device” under the “Source” section. Click on the “…” button next to the “File name” field to select the backup file. Then, click on “Add” to add the backup file to the list.
Step 5: Specify the Restore Options
Once the backup file is added, you need to specify the restore options. For example, you can choose to restore the database to a new location, overwrite the existing database, or leave the database in a restoring state.
Under the “Restore options” section, you can select options like “Overwrite the existing database,” “Preserve the replication settings,” or “Close existing connections to the database.” You can also choose the “Options” page to specify other restore settings like “Recovery state,” “Restore options,” and “Restore plan.”
Step 6: Start the Restoration Process
Once you have specified the restore options, click on the “OK” button to start the restoration process. This may take a few minutes or hours, depending on the size of the backup file and the speed of your server.
Step 7: Verify the Restoration
After the restoration process is complete, you need to verify that the database has been restored successfully. In the Object Explorer, refresh the Databases folder and look for the restored database. You can also run some queries to ensure that the data has been recovered successfully.
Conclusion
Restoring a database can be a daunting task, especially when dealing with critical systems and sensitive data. However, with the right tools and techniques, it is possible to recover the database quickly and effectively. In this article, we discussed how to restore databases with 2023 R2, a version of Windows Server. By following the step-by-step guide, you can easily restore your database and minimize the downtime of your business.

windows server 2023r2 虚拟桌面被删除了怎么恢复
擦除技术是Windows Server 2023和Windows Server 2023 R2的自带功能。这种技术在磁盘卷中查找重复的内容，保留一份副本并删除其余重复的部分——而且在数据被移除的位置会插入一个“链接”指向保留的那搜纤岩份数据块上面去。这是一项很有效的用于回收可用存储空间的技术，前提是磁盘卷很多内容与其他内容没有太大差别。想象一下ISO库，同一个文件多个版本的文件共享（类似修正跟踪）；还有你可能不会想到的另一个应用： VDI部署。在VDI部署中的这些虚拟机，即使你使用不一样的磁盘，里面也包含了成千上万相似的操作系统库和可执行文件。在VDI部署环境中启用数据删除功能省下的磁盘空间能够超过90%，其他类型的内容可以压缩50%甚至更多的空间，而且这一切不会对性能产生可感知的影响。所有的这些都包含在你的Windows许可证里面。
Windows Server 2023 R2在数据删除功能上引入了几个改进，包括在扩展文件服务器和集群共享卷上启用这个功能的能力。Windows Server 2023 R2也特别针对VHD和VHDX文件进行了算法的优化，并且增强了Windows写入磁盘的效率和磁盘算法的优化，从性能的角度来说，不会怪罪于为生产部署的虚拟桌面基础架构中活动的VHDX文件。需要注意到的一点是，Hyper-V宿主机和托管存储卷的机器启用的数据删除一定是不一样的，因为使用Hyper-V上有活动的虚拟机负载，数据删除可能会消耗Hyper-V所能承受的系统资源。
数据删除作业
数据删除包含了3种世御在一定间隔时间重复执行的作业：
优化作业：这个工作执行着核心的分析和从磁盘卷中移除重复内容。它还执行竖段着使用内置算法压缩大块文件的工作，使文件的大小得到平衡，而不会受到解压时对性能的影响。
