The key to WordPress backup recovery is prevention, and regular backups are the best way to avoid disasters. When recovering, use reliable tools such as UpdraftPlus and make sure to recover first in the test environment to avoid potential problems. Preparations include ensuring database backup and backup file integrity. The recovery process may encounter various problems, such as incompatibility of database versions, errors in file permissions, plug-ins or topic conflicts, requiring technical and problem-solving capabilities. Multiple backups and multiple tests are important steps to ensure website security.

WordPress website backup and recovery: The path to advance from a novice to an experienced driver

Many friends have asked me about WordPress backup and recovery. In fact, it is simple and simple, and complicated. The simple thing is that there are many tools and the operation steps are clear; the complicated thing is that there are all kinds of strange problems that may be encountered during the recovery process, and how to do it quickly and well without any hidden dangers. In this article, let’s talk about this matter, from the most basic operation to some advanced skills, as well as the pitfalls I have struck over the years, I will tell you.

Let me talk about the most core first: backup and recovery matters, prevention is better than treatment! Don’t wait until the website is out of date before you remember the backup. At that time, it was too late to cry. Regular backup and develop habits are the king. As for backup tools, I personally prefer to use UpdraftPlus, which is simple and easy to use and powerful, and the free version is enough. Of course, other backup plug-ins, such as BackWPup, are also pretty good, just choose the one that suits you.

Next, let's assume that you already have the backup file and now you want to restore it. Remember, be sure to prepare before recovery:

• Test environment: Never recover directly on the production environment! Find a test environment, such as a local virtual machine or other server, and first test whether the recovery is successful to avoid the website being paralyzed due to the recovery failure. This step is very important, don't bother.
• Database backup: In addition to website files, database backup must also be included. Website files and databases are indispensable.
• The integrity of the backup file: For the downloaded backup file, be sure to check its integrity to avoid recovery failure due to file corruption. You can verify it with the checksum tool.

OK, the preparations are done, and we will start to recover! Suppose you are using UpdraftPlus, the basic steps are as follows:

 <code class="bash"># 這些命令只是示意，實(shí)際操作可能需要根據(jù)你的環(huán)境和工具進(jìn)行調(diào)整。 # 以下代碼片段并非實(shí)際可執(zhí)行的命令行代碼，僅用于示意。 # UpdraftPlus 的操作主要在WordPress 后臺(tái)進(jìn)行，而非命令行。 # 1. 登錄WordPress 后臺(tái)# 2. 找到UpdraftPlus 插件# 3. 點(diǎn)擊"Restore" # 4. 選擇備份文件# 5. 選擇恢復(fù)選項(xiàng)(通常包含文件和數(shù)據(jù)庫) # 6. 點(diǎn)擊"Restore" 開始恢復(fù)過程# 整個(gè)過程需要耐心等待，時(shí)間長短取決于備份文件大小和服務(wù)器性能。</code>

This looks simple, right? However, there are many pitfalls here:

• Database version incompatible: If your backup file is an old version of WordPress and your server is a new version of MySQL, there may be a problem with database version incompatible. Workaround: Either upgrade the database or downgrade WordPress.
• File permissions problem: After recovery, file permissions may be set incorrectly, resulting in the website being unable to access normally. Solution: Check file permissions to ensure that the permissions for all files and directories are set correctly.
• Plugin conflict: After recovery, plugin conflict may occur, causing the website to crash. Workaround: Disable the plug-in one by one to find the conflicting plug-ins.
• Topic conflict: Similar to plug-in conflict, topics may also conflict. Workaround: Switch to the default theme.
• .htaccess file problem: The .htaccess file may be corrupted or lost, resulting in a 404 error on the website. Workaround: Regenerate the .htaccess file, or restore it from the backup.

Therefore, the recovery process is not a simple click of the button, it requires you to have a certain technical foundation and problem-solving ability. When encountering problems, don’t panic, carefully check the error log, analyze the cause of the problem, and solve it step by step. Remember, more backups and more tests can prevent disasters from happening to the greatest extent.

Finally, a little experience: regular backup, reliable backup tools, and test the recovery process. These three points are indispensable. Don't wait until the website is closed before regretting it. Don't be lazy, the fate of your website is in your hands!
