Use differential, incremental, and full backup to make your data safe. If you are an enterprise user, a single backup method may not satisfy your need. It offers you the reasons to choose differential backup or not to choose it. This article explained the advantages and disadvantages of differential backup. It is hard to say which backup method is better because they are all useful in some situations. The differential backup file will get larger and larger as time goes by, even getting bigger than the full backup.ĭifferent backup methods have different features.Although a differential backup is faster than a full backup, it takes less time to restore a full backup than a differential backup.The file may be damaged while a differential backup process.A differential backup still needs the previous full backup to operate. Differential backup is easy to restore.Differential backup is a time-saving backup method. It will not take too much time to finish a differential backup.Like incremental backup, a differential backup does not need to back up too much data or files as a full backup.Here are some advantages and disadvantages of differential backup: Differential backup solves part of the problems that incremental backup has, and it reduces the probability of file corruption and is easier to restore files than an incremental backup.Īdvantages and Disadvantages of Differential Backupĭifferential backup is an excellent way to back up changing data, but it is not perfect. On Tuesday, the backup file contained the changing data after the previous incremental backup. If you finished a full backup on Sunday, then on Monday, an incremental backup only contained the changing data after Sunday. If one file is damaged, we can not recover all the data successfully. However, restoring the whole date with incremental backup is super complex. The incremental backup file takes up a little space, and creating an incremental backup file won't take too much time. You need to back up a small amount of data once a time. Incremental backup means copying the changing data after the last backup, which may include a full backup, a differential backup, or an incremental backup. Both of them copy the changing date, but there are differences. Incremental backup and differential backup are often mixed-up by people. Incremental Backup VS Differential Backup
It copies fewer data than the full backup, so you can frequently create a differential backup.Differential backup is still imperfection, and when the backup cycle gets longer, a differential backup gets closer to a full backup. A full backup is suited for a long-term situation like monthly.ĭifferential backup relies on full backup because it records the changes after the last full backup. We need more time to make a full backup file, which may take up more space on your computer. It is a well-known backup solution, many articles introduce full backup, and it is easiest to understand. Wednesday: You add three files and perform a differential backup. You will get two image files you added on Tuesday and three newly added image files.įull backup means copying all the data and files once a time.You will get two newly added image files. Tuesday: You add two files and perform a differential backup.What does a differential backup doįor example, if you did a full backup on Monday, Tuesday's backup backs up all the files added since Monday's full backup. When you need to restore the data, use a full backup and the latest differential backup to do it. The differential backup may help you a lot. If you find backing up all your data daily impossible, your data will not change too much daily. That is why we need the differential backup. 02:44 How to create a better backup strategyĪfter a full backup, the data will change daily or weekly, and the disk space does not allow us to do full backups daily.02:01 Features of full, incremental, and differential backup.00:42 An example to explain the differences.There are 4 crucial timing points you may not want to miss. To better understand the differences between differential, full, and incremental backup, we provide you a 3-mins video. It can copy all the data and files that have changed since the last full backup. The differential backup starts with a full backup, so a differential backup depends on the full backup. PAGE CONTENT: What Is Differential Backup Full Backup VS Differential Backup Incremental Backup VS Differential Backup Advantages and Disadvantages of Differential Backup What Is Differential Backupĭifferential backup is one of the data backup methods, and it can backup files, folders, and hard drives.
