Troubleshooting an incomplete backup:
Possible error messages during a backup include:
CPF3771 - xxx objects in library saved; yyy not saved.
CPF32B3 - Cannot allocate object for file xxx in library yyy.
CPF3741 - File xxx in library yyy not saved.
Typical reasons these error messages happen include someone still being signed on to the system and having the file locked. Be sure all of your users are signed off when the backup starts.
A job can be added to the scheduler to end QINTER to ensure all users are off.
