A differential backup is a type of data backup that copies all files that have changed since the last full backup was performed. This includes any data that has been created, updated, or changed in any way, and does not copy all of the data every time. After you set up a differential backup schedule, the accumulated backup data is copied once it is started.
For example, if a full backup is performed on Sunday, then a differential backup on Monday backs up all files that have changed or been added since Sunday’s full backup. A differential backup performed on Tuesday in turn backs up all files that have changed since Sunday’s full backup, including the files that changed on Monday – and so on every day.
With the development of information society, the use of computers has become more and more common. Data security has always been a key consideration for computer users, so backing up data has been an essential part of daily life. Generally speaking, there are three means of backup, namely, Full Backup, Incremental Backup, and Differential Backup.
Nowadays, doing system differential backup is popular among computer users. The backup and restore tool in Windows 7 does incremental backup by default. Differential backups cannot be done by Windows 7 built-in tools. The advantage of differential backups over incremental backups is that in recovery, you only need the last full backup and the last differential backup to get a complete recovery. What’s more, it can help improve backup efficiency and reduce the storage disk space required for image files.
