Daily backups on external usb disks - no clean up
I am trying desperately to create a daily full backup of a hyper-v host (server 2016) and its virtual machines onto external usb drives that are being changed on a daily basis (a total of 7 usb disks).
Unfortunately the backup cleanup does not work as expected.
I've tried several different settings ranging from "keep 5 backups" to "use 900GB max" - no cleanup will ever happen.
Am I missing something here? Is the cleanup disk-specific?
How is it possible to create a daily complete backup onto seven disks that never run full? :)
I came across this KB article: https://kb.acronis.com/content/58372
It basically tells me to write a batch script to do the cleanup when using changing usb drives. Is this some kind of joke?
Any help you can give me is highly appreciated!
