windows 2008 R2 server backup - destination full

We run a Windows 2008 R2 backup to a locally attached ESATA drive. (We are running Core Server). Though the backup is incremental and supposed to recycle  it isn't doing that and now the backup unit is full. Is there any way we can manually make it recycle as it should have all along from a certain point so as to give us space on the drive again? We don't want to completely wipe the drive.  If we can't do it from the GUI, what about from the Core command line? Powershell?

Try this, mine was an upgrade to Windows 2008r2 and the switch was set to 1

HKLM\System\CurrentControlSet\Control\FileSystem\isNtfsDisableLastAccessUpdate\ (REG_DWORD) 1

I set it to, 0 and my incrementals began working again.

just the first place to look
