All you need to do buddy is inventory the tape in Backup Exec. It will find a Backup Exec media label on the tape, but it will know that this tape doesn’t belong to this Backup Exec installation. So it will move them to the “Imported media” media set.
An inventory and then a catalog is all you should need to be able to restore data from another Media Server.
We do this once a week after transporting our Sunday tape over to the Disaster Recovery site and restoring the data on to the duplicate system there.
If the system is crashing when trying this, I would highly recommend setting the BUE Debug on (http://seer.entsupport.symantec.com/docs/275639.htm) and also checking those Event and System logs to see if you can get any useful errors.
You may have a corrupt catalog database there and it might be worth running through the procedure to remove and start again.
BTW: I have always found Symantec Support to be pretty good.
1. try to restore by media (check your media label)
see whether you can see your media there.
2. goto media tab check all media
i want to know what is your used capacity
the reason i am asking is i want to know whether you have span your tape …
BTW: I also found Symantec Support is very good. They can work with you 1 to 1.
