Third, incremental backup (incremental backup)
Literally, incremental, that is, comparing the last additions, an incremental backup is an efficient way to backup, because it only backs up the last modified file, which is marked with the archive attribute, rather than backing up all of the selected files. As we've discussed in the previous section, after a normal backup, the archive tag of the file is purged, and the incremental backup is only backed up for files with an archive tag, because the program believes that since the file has been archived, that means it has been modified and naturally needs to be backed up again. As a result, incremental backups are typically not used alone, but are used concurrently with normal backups.
There is such a scene. I have 5 txt files here, such as figure
To make it easier for me to identify the document's properties directly, because it's a new document, it's labeled A, which means archive archive.
First, make a full backup of these 10 files and name them firstfull.bkf.
Store it in the following path:
After a normal backup, the archive properties of the 5 txt files have been cleared.
