The importance of a habit
This is a digression. A habit even plays an important role in a person's life-this sentence is too chicken soup to expand. The most important thing for a webmaster is persistence, and persistence here is habit. The same is true for website backup. All premises are that you need to develop the habit of website backup. Simply put, website backup is nothing more than entire site backup and
database backup. In the actual backup process, the webmaster can use a variety of backup methods to protect the website according to the procedures used on his website and the stability of IDC.
Backup of the entire site
For website file backup, or the backup of the entire site directory, generally speaking, except for some regular backups and backups for special events. Generally, when there are changes in website files, it must be backed up once, such as website template changes, website function additions and deletions. The purpose of this type of backup is mainly to worry about website file changes causing instability of the entire website or causing other website functions And loss of files. Generally speaking, since the frequency of file changes is relatively small, the backup cycle is relatively long, and website files can be backed up before each change of website-related files (such as changes in functions). For website files or the backup of the entire directory, generally we can package the entire site directory and download it locally through remote directory packaging, which is the easiest way. For some large websites, the website directory contains a large number of static pages, pictures, and some other applications. We can use the FTP tool to download the relevant files in the website directory directly to the local, and implement regular packaging and localization according to the backup time. replace. This can maximize the security and integrity of the website.
Database backup
The importance of database for a website is self-evident. If the website file is damaged, we can use some technical restoration methods. For example, if the template file is lost, we can change a set of templates; if the website file is lost, we can reinstall the website program again, but if the database is lost, we believe that the webmaster with the strongest technology Is also powerless. Compared with the website database, the frequency of changes is very large, and the frequency of backups is relatively more frequent. Generally, some IDCs with better services usually help to back up the database once a week. For some webmasters who use website building CMS as website, such as Discuz, PHPwind, DEDECMS and other website building systems, there are very convenient one-click database backups in the background, which can be automatically backed up to the designated website folder. If you still do not Rest assured, you can enter phpmyadmin, export and download the database to the local, and truly realize the local and remote backup of the database.
