I have a job that should run once a 3 weeks to a disk base storage and backup some of my Hyper-v Vm serves. This job has a retention date of 4 weeks.
We run this job at 09/15/20 and it should get expaired at 10/13/20, but now when go the storage I can see that the VMs are showing expired! why is that? Why should BE 21 decided to expire the backup sets? I changed the retention date to 8 weeks but the VMs still shows expired!!
