MSSQL 数据库备份和还原的几种方法小结,配有图文,大家看了就知道了。
一、通过企业管理器进行单个数据库备份。打开SQL SERVER 企业管理器,展开SQL SERVER组LOCAL下的数据库,右键点击你要备份的数据库,在弹出的菜单中选择所有任务下的备份数据库,弹出备份数据库对话框:点击添加按钮,填写备份文件的路径和文件名,点击确定添加备份文件,点击备份对话框上的备份,开始进行备份。
二、通过企业管理器多数据定时库备份。打开SQL SERVER 企业管理器,展开SQL SERVER组下的管理节点,右键单击数据库维护计划,选择新建维护计划。在弹出的欢迎对话框中选择下一步,然后显示如下对话框:
选择你想要备份的数据库,下一步。在接下来的一步中,我们默认所有选项,下一步。在当前对话框中可以选择是否检查数据库的完整性,这里我们默认就可以进行下一步就行了。对话框入图所示:
选中作为维护计划的一部分来备份数据库,点击更改按钮修改备份数据库的时间,单击下一步,入下图:
在这里,我们可以选择“使用此目录”为备份指定路径,选中“删除早于此时间的文件”可以指定备份文件的保留时间。
下面的几个步骤我们都选择默认设置,最后在完成对话框里为备份起一个名字,点击完成后,数据库会在你指定的时间进行备份。关于数据库维护计划的更多知识请查看其它相关资料。
三、备份数据库文件。打开SQL SERVER 企业管理器,展开SQL SERVER组LOCAL下的数据库,右键点击你要备份的数据库,选择属性。在弹出的对话框中选择数据文件,在这里显示了数据文件的路径,如下图:
打开SQL SERVER 服务管理器,将SQL SERVER 停止。然后打开我的电脑,找到数据文件路径,将其拷贝出来进行备份(注意同时备份.LDF文件)。
最后开启SQL SERVER服务
四、回复数据库备份文件(适用于用企业管理器备份的数据库)。打开SQL SERVER 企业管理器,展开SQL SERVER组LOCAL下的数据库,右键点击你要还原的数据库,选择所有任务下的还原数据库,弹出如下对话框:
选择从设备,点击选择设备,为还原添加备份文件路径,然后进行确定还原。
五、还原数据库备份文件。在企业管理器中对数据库节点右键单击,选择所有任务下的附加数据库,弹出附加数据库对话框。如下图:
选择一个你之前拷贝的数据文件,然后点击确定即可附加成功(注:如果数据库已经存在,请删除数据库后在对其进行附加)。

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

There are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

The main difference between MySQL and SQLite is the design concept and usage scenarios: 1. MySQL is suitable for large applications and enterprise-level solutions, supporting high performance and high concurrency; 2. SQLite is suitable for mobile applications and desktop software, lightweight and easy to embed.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid

Using transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
