windows server 2022 incremential backup not working

Question

We have windows server 2022 servers. We turned on the Windows server backup feature on these servers. We want to take an incremental backup. But it takes a full backup every time. We tried most solutions found on the internet. We marked the relevant disk as incremental in the performance settings. But he took a full backup again. How do we get incremental?

Hi,

Windows Server Backup will, by default, create an incremental backup that behaves like a full backup. It manages full and incremental backups automatically.

There are several reasons which may cause the backup to be full instead of incremental:

1. Backup on the target is deleted/not present.
2. Source volume snapshot is deleted, from which the last backup was taken.
3. 14 incremental backups have occurred since the last full backup
4. More than 14 days have passed since the last full backup
