Terastation daily differentials are overwriting themselves and not appending

I have Backup Exec 9.1.  I do daily diffs to a Terastation Monday through Thursday.
This includes a full backup of Exchange and the system state, and daily diffs of our data on the fileserver (mostly AutoCAD files).
All of a sudden they are not appending, but overwriitng each other even though they are about 80 GB each and the drive has 633 GB of unused space.  My plan is to copy everything off the terastation to a new NAS device, format terastation and then put everything that I put on the NAS back on.  Will this work?  Will I have to rebuild the B2D folder?  I am relatively new to NA so please be specific.

Hi,

Few things can cause this.

Is the job set to over-write ? (or overwrite if it can't find appendable media?) (you can find this by right clicking the backup job and going to properties then device & media)

Do the 80gb segments have over-write protection on them? (protected from appending) (you can find this out by clicking the media tab then the media itself - it should tell if if there is any protection)

if you format the NAS box you will have to resetup the backup to disk folder, it should only take a minute or two and isn't a big job.

OK, when I went to the media tab, the append media was set to hour.  I changed it to 1 week since our differentials are Monday through Thursday.  Is that correct?  And thank you by the way.

The append period is how long you will allow data to be appended to the media.
For your set-up; I would set it to Infinite.

For your backup ; this is what I would do:

Create a new backup to disk folder and point it to the NAS box.

If you use the wizard it will ask "Do you want to allocate the maximum size when creating backup to disk files?"

Select "No"

This will create 1 image file on the NAS box which will expand as you backup to it.

Then, In your backup job, set it to "Append to media, Overwrite only if no append-able media is available."

If you really want to stop it overwriting then set it to append only, this however will require you to clean up the NAS box once it fills up.

Hope this helps.
