How to Only Backup Changed Files Per Day Automatically
This article tells you how to only backup changed files per day automatically with a free backup tool. It helps you create incremental/differential backup instead of full backup.
Why backup files automatically?
We use computer every day, and the data is increasing with the use of computer. There are many important files stored on the computer. In case of losing important data, users always backup files to other storage devices like another disk, or even synchronize files to cloud storage. But making a backup every day seems annoying, and you may forget to back up. Thus, it is necessary to make a schedule backup that can backup files automatically.
Backup only changed files per day automatically
Backing up changed files per day automatically will be very useful to users. But how to do it on Windows 11/10/8/7? First, you need to figure out different backup types.
◑ Full Backup will backup all the data whether the newly added or existing files. People usually do a full backup for the first time. As time goes by, the data will increase, and after a period of time, you’d better backup again to ensure the new data’s safety. However, full backup will duplicate both the old existing data and newly added data, so it will take more time and occupy more space. There is no need to do a full backup again.
◑ Incremental backup refers to backing up the changed and newly added data based on the last backup (either a full backup or an incremental backup). There is a mutual relationship between the backup images. The new image file of incremental backup is based on the previous image file. The deletion of a previous image file will make all the subsequent image files invalid.
◑ Differential backup is used to back up the changed data based on the last full backup. Compared with the last full backup, if there are data changed, added, or deleted, it will backup the changed files to the destination place. It can help to improve backup efficiency and reduce the storage space required by the image file.
If you only want to backup changed files per day automatically, what you need is to do an incremental backup or differential backup.
