Status 25 is the NBU dump error code for ... "Sorry, I don't know what's going wrong"
So, don't try to check any connectivity problem. That can come from anywhere.
Maybe a memory problem ... Access to the database ..
For a restore, do you try to restore your database to a different machine ? Source is not the Destination ?
If so, for SQL, you must use the ALTERNATE client restore.
On the master server, under :
/usr/openv/netbackup/db/altnames
x:\VERITAS\NetBackup\db\Altnames\
Create an ascii file named as the SOURCE machine. As the only line in it, write the name of the DESTINATION machine.
Any DATABASE restore is considered a USER restore, therefore can be done by default only from and to the SOURCE machine.
