When using Windows Backup on servers it seems that the backup drive can get full. MS is suppose to automatically clean up backups but I find it does not.
For my example I have a backup drive on G: drive. To clean up old backups off this drive you open a command prompt with Administrator privileges then type the following:
diskshadow
Then type one of the following.
To delete just the oldest backup type:
delete shadows oldest G:
To delete all the shadow backups from G:
delete shadows volume G:
