Backup Exec 12.5 with RD1000

I am using Symantec Backup Exec 12.5 on SBS 2008 backing up to a Dell RD1000 160GB removable disk cartridge, however I keep running out of space.  The backup jobs are set to use a media set that has a no overwrite protection and I am rotating 2 data cartridges. The logs show that the nightly jobs begin by reclaiming space from expired media. I've found however, that it is not deleting copies of the exchange folder backups.  On each cartridge, I see several folders IMG0000## that contain the priv1.edb, .stm, etc files from months ago. If I manually delete these older folders I can reclaim space, but there must be a setting somewhere that I'm overlooking that will automatically expire and overwrite these old folders.  

I have checked the registry key HKLM\Software\Symantec\Backup Exec For Windows\Backup Exec\Engine\Misc\AutoExpireGRT. And that is set to 1 already which I know has been suggested in other posts. (

Also Tools / Options / Media Management. Media overwrite protection is set to none.
I'm sure I could write a batch file that could do the job, but I'd rather accomplish it properly through Backup Exec.

Hey betoni

In the properties of the job under the device and media section,
you can specify,
append to media overwite if no appendable media availible

append or cancel if no appendable media availible,

Also ensure on the media, the the device is set to always appendable if space

Hope this helps
Check media management pane in Tools-> Options and see if that addresses your concern
