I have a production server (10TB - 1.69TB used) which I have been using MS Server Backup backing up to vhdx files on a NAS as I like to keep 2-3 weeks worth of backups. However due to some network and capacity issues at the NAS end I've had to make several other vhdx files in other places and switch the schedule to those. Today was a day when I wanted to start fresh and to create a new empty vhdx container in a different location and once working correctly clear up the old vhdx files, but when I set a new backup going the amount of data it was backing up was a lot less than the used space on the drive indicating to me it was doing an incremental. So I've:
1) Created a new empty 12TB dynamically expanding vhdx file
2) Deleted the existing schedule and created a new one, set the backup going
What would happen if I remove the old vhdx files? Presumably it would mean I don't have a full back of this server..
Is there anyway to clear MS Backup's references to old backups and start fresh?
