Backup Exec is not appending backups

I'm backing up to a Network Attached Storage box.  I have two servers running Backup Exec 10.  One server is backing up just fine to the NAS.  The other throws up this error:

No appendable media could be mounted.
Switching to overwrite operation on scratch media.

The backup completes just fine after this error, but it overwrites the previous backup and I want it to append.

Check the "media set" you are targetting for this job. It has no appendable media available.
You can define the amount of time you can append to a tape by looking at the properties of the media set.If previous media is being overwritten, you may also have to change the "Overwrite Protection" setting of the media set. I can't remember, but if a tape is not overwrite protected, you may not be able to append to it.

There are a few snags: Media in the scratch pool, i.e. media that has just been erased by a quick erase for example are never appendable.

Thanks, I think that was it.  I am going to leave this question open for a week or so in case there is a problem, then I will follow-up.

Here is another question in the meantime, when the NAS fills up, will Backup Exec automatically write over the oldest backups or is there some place I need to tell it that?

Go into Tools/Options/Media Management. Make sure to have the "Overwrite recyclable media in the targeted media set before scratch media" selected.
Then anytime a piece of media reached reaches the end of the overwrite protection period, it will be reused.
