For some reason, out of 15 Hyper-V backup jobs, three jobs just keep on accumulating restore points. For most jobs, retention policy is set at 60 days. With these three jobs, the oldest file on disk was a full backup (vbk) file, followed by ~220 vbr files. We use Incremental as a default, synthetic full every weekend. Appearently, this has not worked for quite some time.
I assumed that if I ran a manual Full backup, this would release the restore points to be removed. However, this didn't work as expected. The job finished without any mention of "Removing ********.vrb as per retention policy". I've even set the job storage setting to Reverse Incremental and ran another full backup.
Now I could just remove the restore points manually, but I'd like to keep things clean and I would like to see this working properly again. Any suggestions?
