Can Windows Server Backup Do Incremental Backups? This is a question that plagues many people, from the official answer alone, the answer is yes, but sometimes users complain Windows Server Backup not doing incremental backup. You may not want to encounter this problem, but you are currently in this situation or want to create Windows Server 2019 incremental backup without any obstacle, you can continue to read this article and follow the steps carefully. 

Windows Server 2019 Incremental Backup

Before you start to create Windows Server incremental backup, the first thing is to learn its meaning and if you need to do it. 

What Is Incremental Backup in Windows Server? 

The incremental backup is a new backup method after full backup, which backs up only changed data since last backup, such as, deleted, modified, or newly added. Compared with full backup, it greatly reduces the backup time and disk space usage.

Note: Based on the backup rule, the last backup can be full backup or incremental backup. So all of them are linked together, and you cannot restore backup image if one of them missing or damaged.

Why Perform Windows Server Incremental Backup?

From the meaning, you may get some of the reasons. Here we summarize the top three reasons for you.

  • Faster backup speed: The Incremental backup will run faster, because only increments are backed up.
  • Higher backup frequencies: In view of its faster backup speed, you can run multiple incremental backups as often as desired and each increment being an individual recovery point.
  • Less storage space: It requires the least storage space compared with full backup.

If you are sure you want to create Windows Server incremental backup, please continue to see below and learn how to deal with Windows Server Backup not doing incremental backup or configure incremental backup successfully.

The problem: Windows Server 2019 Backup Not Doing Incremental Backup 

"Hi, I've installed Windows Server 2019, and there are users sharing files stored on the drive, and I installed "Windows Server Backup" to backup the files. But why does Windows ServerBackup always run full backup, instead of incremental backups after the first full backup?
I set it to daily task backup, and I use NAS HDD with ISCSI connection for the backup destination disk, and use HDD for another server, but both of them run a full backup.
Can you tell me the reason, and what method to do to get an incremental backup in Windows Server 2019? Thank you in advance"

This can be a problem for many users, and don't know how to deal with it. The first reason is you don't configure backup settings correctly, just check it with the following steps.  

At the same time, you may schedule incremental backup to network share, in this case, it will only create full backups instead of incremental backups. If you are in this situation, try third-party backup software supporting incremental backup. 

Besides, you may use removable media, such as tape, CD, USB flash drive, etc, which is not supported by Windows Server Backup. If not, there is a possibility that the last backup is not deleted, just keep an eye on it for a while.
