What is full backup, differential backup, and Incremental backup?

Introduction to Backup Types and combined backup solutions
Full backup
Backing up all selected folders does not depend on the file archive attribute 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 ).

Differential backup
Differential backup is for full backup: All files that change after the last full backup are backed up.
(During differential backup, only the marked files and folders are backed up. It does not clear the mark, that is, it does not mark it as a backup file after backup, in other words, it does not clear the archive attribute ).

Incremental Backup
Incremental backup is for the last backup (no matter which one is used): All files that have changed since the last backup.
(During the Incremental backup process, only the marked files and folders are backed up. This removes the mark, indicating that the files are marked after the backup, in other words, the archive attributes are cleared .)

 

Examples of different Backup Types

Full backup and differential backup
Perform full backup on Monday and differential backup from Tuesday to Friday. If the data is damaged on Friday, you only need to restore the full backup on Monday and the differential backup on Thursday. This type of policy takes much time to back up data, but it takes less time to restore data.

Full backup and Incremental Backup
Perform full backup on Monday and Incremental backup from Tuesday to Friday. If data is corrupted on Friday, you need to restore normal backups on Monday and all incremental backups from Tuesday to Friday. This type of policy takes much time to back up data, but it takes less time to restore data.
