How to Only Backup Changed Files Per Day Automatically?

Backup files automatically

Now, we use computer everyday, and the data is increasing with the use of computer. We store many important files on the computer. In case of losing the important data, people always backup files to other storage space like another disk, even synchronize files to cloud storage. But backup every day seems annoying, and people always forget to back up. Thus, it is necessary to make a schedule backup that can backup files automatically.

Only backup changed files per day automatically

Backup changed files per day automatically will be very useful to users. But how to do it? First, you need to figure out the difference of backup types.

Full Backup will backup all the data no matter new added or the existed files. People usually do a full backup at the first time. With 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 the old existed data, so it will take more time and occupy more space. It is no need to full backup again.

Incremental backup refers to backup the changed and new added data based on the first full backup or the last backup. There is a mutual relationship between them two. The last 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. It will backup the different files based on last backup. If there are data changed, added, deleted, it will backup the changed files comparing of the last full backup. It can help to improve backup efficiency and reduce storage disk space required by the image file.

If you only want to backup changed files per day automatically, what you need is to do a schedule automatic daily backups of changed files.
