Original link:


The advantage of frequent website backup is that it can be quickly restored after encountering a problem, which is not so passive, prevents information loss, and has great operability. Although it is very easy to build a website, in order to deal with various unexpected situations on the Internet and avoid your own website being in vain, it is very necessary to make a backup of your website.

Now mailbox receiving supports attachment files, and it is also a good backup method to backup website files and database files to our own mailbox, and also prevent the loss of backup files.

The size of the attachment file received by the mailbox depends on the mailbox service used. Generally speaking, personal blog website source files, database files are not large, and common mailbox services can be used.
