I'm a little confused here
The first job is a normal backup that happens 1 time a year,
OK, no problem
the other one is a normal backup too, but happens every day.
Thsi other job, is it append? How often do you run it? Sounds like the tape would fill up real fast if it is append
You can also shut down all BackupExec services, rename the catalogs directory (eg:catalogs.sav) and restart the services. BackupExec should create a new-empty catalogs directory. Inventory and catalog again (make sure that "Use media based catalogs" is NOT checked.
This should read the tape itself and rebuild the catalog for every file that exists on that tape
