Veritas 8.6
I have a internal tape backup (DDS4) in my DELL server and bundled with veritas backup exec 8.6. I am not familiar with veritas, I went to veritas website and still can't find the info that I want. I wanted to erase off all the data in the current tape and do a new backup again with that tape. Do I need to create a new media set in veritas ? How am I going to test whether my backup data is OK ? Do anybody have a step by step guide where I can set a proper backup procedure in veritas ? Help !

In the Backup Exec device manager GUI, you can right-click on the drive icon, than click on "Quick-Erase". This will erase the header off the tape cartridge and use it as it were a new media. (Once you erase the tape. Backup Exec will place it to a default media set). There is nothing else you need to do as far as media sets.
When you run the backup is complete, Backup Exec will re-read (verify) all data on the tape catridge from that backup set to insure that all data on the tape is valid.
I think Backup Exec has a wizard to help guide thru a backup process. Even without the wizard, it is very user-friendly.
As far as steps:
1. Quick Erase the media
2. Select the Backup tab.
3. Select your drive letter to back up.
4. Submit the job.

Below is part of the error I got, and the Job is failed:
"No appendable media could be mounted.
Switching to overwrite operation on scratch media.
Drive and media information from media mount:
Robotic Library Name:
Drive Name: DELL 1
Slot: 0
Media GUID: {4D9DA39B-C01E-4FC1-93FB-2D4AF7967595}
Media Label: FULL_ECG
Overwrite Protection Time Left: Infinite
Append Time Left: Infinite
Targeted Media Set Name: Media Set 1"
I tried on another tape also the same result, is the tape full, how am I going to know that when a tape is full ? Thanks.

If you are using a brand new peice of media, all you need to do is quick erase it and it should be ready for backups. Since your current media is already used, first inventory the media, than under the "media' section, move the media to the "scratch pool". This should allow the media to be overwritten.
Have you done a quick erase yet? The log you posted seems like info from a backup attempt?
The condition you created is that your media is "well protected". That is, when you originally installed Backup Exec, the settings may have been set for FULL protection. There are settings in Backup Exec that allwo for no protection, meaning that media can be overwritten at anytime.
You will know when a tape is full when during a backup operation, Backup Exec asks for a second tape cartridge.

1) Quick erase writes an indicator at the beginning of the media and the contents of the media are made inaccessible. This means my tape's was still occupied with data, what if I would like to make it blank (like a totally new blank tape)? I do not have the option to do long erase !
2) If I erase my daily tape (differential/incremental on new and changed file backups) and start all over again with the same media set, as what I know the daily backup will set the archive bit on/off. Will the data's archive bit set to off again in order to let me backup the previous data again ?
Hope you can understand what I am trying to do !

Media Protection is very important to understand if you want to "protect" media from being overwritten. Veritas Backup Exec has excellent documentation on each of the protection level settings. Partial will only allow scratch and imported media to be overwritten. If a media is in the media set and the overwrite protection has not expired, than the media can not be overwritten.
Have you been able to erase and overwrite media?
