Once again - NetBackup does not work like that.
NetBackup works stricktly according to Retention Level and will merely append to same tape.
A tape can only be overwritten when all images written on the tape have expired.
There is no need to manually keep track of where images reside. NetBackup does a very good job doing that.
When you want to restore, simply select the client and the date that you want to restore from and select files/folders.
NBU will display the media id needed for restore.

Are you referring to the Backup Exec 'overwrite protection' feature associated with tape media?
NBU does not work like that.
NBU uses the retention level that is selected in Policy Schedules.
A tape can be appended to as long as all relevant parameters are the same (e.g. volume pool and retention level).
NBU will allow tape to be overwritten when all images on a tape has expired.
You can see when the last image on a tape will expire with this command:
bpmedialist -m <media-id>

Hi,
Netbackup will not overwrite any tape till data will expire ...so no need to set "overwrite protection "

I mean I want the backup image is located to consecutive tape.
Example :
Week 1 - The Full backup is located to Tape 1 after that the Tape 1 will be locked to prevent the other policy overwrite to it
Week 2 - The Full backup is located to Tape 2 after that the Tape 2 will be locked to prevent the other policy overwrite to í
......
It's very helpfull to help me check which backup image resides in which tape
Thanks !

NetBackup is not really designed to work like that - the idea is you give it a load of tapes (or disk space) and let it get on with it ...
However, if you wish to 'lock' a tape, simply right click the tape in the GUI, and choose 'suspend'.
The images on a particular media can be seen with bpimmedia command.
