Disadvantages: take up a larger hard disk space.) -* Incremental backup: refers to the backup of the data updated after the last full backup or incremental backup. The process is like this, such as a full backup on the first day; a backup of the newly added data on the second day, as opposed to a full backup; on the third day, a backup of the newly added data on the basis of the second day. , Relative to the next day.

For example, a full backup on the first day; a backup of the new data on the second day; a backup of the new data from the second day to the third day on the third day; and a backup of all the new data from the second day to the fourth day on the fourth day. And so on. * Selective backup: Refers to backing up a part of the system. * Cold backup: refers to the backup when the system is in shutdown or maintenance state. The backed up data is exactly the same as the data in the system during this period.
