filegroup backups and partial backups are not covered in this article): 1. Full backup: Replicate all areas (Extent) of the backed up data directly. Here are 2 points worth noting: A full backup does not back up all parts as its name "full", but instead backs up only the database itself, not the log (although only a small number of logs are backed up for synchronization) Full backup the datab

First, Knowledge pointsfull backup: backs up all selected folders and does not rely on the archive properties of the files to determine which files to back up. (During the backup process, any existing tags are cleared and each file is marked as backed up, in other words, the archive attribute is cleared). A full backup is also called a full backup.differential Backup: A differential backup is for full backups: All files that have changed since the las

Two php database backup program codes. John has nothing to do with collecting two php database backup programs today. The following functions can be completed: 1. backup specified data table, 2. package it into a zip file, 3. sent to the specified email address.

. Everything, Hope everything is normal, perfect is almost impossible. Backup is a way to protect data investment. If you have multiple copies of data, you are not afraid of any damage (all you need to do is recover lost data from the backup ). Correct backup is important. Just as everything in the physical world is related to others, backups will become invalid sooner or later. Make sure that the backup is valid. You do not want your backup to be

backups are dependent on different storage engines at the backup speed Physical backups are very fast to restore. But the minimum strength of a physical backup can only be achieved by table Logical backups are usually kept in a purely ASCII structure, so we can use a text processing tool to handle Logical backups
