![]() How to perform cumulative incremental backup in Windows 10/8/7 *Here's a more detailed comparison of incremental and differential backup for your reference. You can make a choice according to your needs. In conclusion, both cumulative backup and incremental can save storage space and backup time, but incremental backup is faster on backing up and cumulative backup (or differential backup) is faster on restoring. ![]() Therefore, restoring from cumulative backup requires a full backup and a subsequent cumulative incremental backup, while restoring from incremental backup requires a full backup and all the subsequent incremental backups till the specific time point. That is, if you create a full backup on Day 1, a cumulative incremental backup on Day 2 and Day 3 respectively, then the backup of Day 2 will contain the changes from Day 1 to Day 2, and the backup of Day 3 will contain changes from Day 1 to Day 3.Īnd if you make ordinary incremental backups on Day 2 and Day 3, the backup of Day 2 will save changes from Day 1 to Day 2, and the backup of Day 3 will only include changes from Day 2 to Day 3. How to perform cumulative incremental backup in Windows 10/8/7?Ĭumulative vs incremental backup, what's the difference?īoth of them only save changed files, but a cumulative incremental backup is based on the last full backup, while an ordinary incremental backup is based on the last full backup or incremental backup.Cumulative vs incremental backup, what's the difference?.Besides, with the latest full backup and a subsequent cumulative backup, you can easily restore data to an earlier version of a specific time point.īut, how is this backup mode different ordinary incremental backup? When and how to perform it in Windows? Cumulative incremental backup is a backup mode that saves only changed or newly added data since the last complete backup, which is more commonly known as differential backup.įor large files that need to be modified frequently, performing full backup will consume a lot of time and storage space, while a cumulative incremental backup can save you from such worries.
