Hypothetically, when you begin the restore, you should
have all the information from the Level-0 forward ,
which includes the information about level-1. The
engine checks two places, the ixbar file and the
sysutils.bar_* tables. Unless you have them in place,
the backup will very likely fail.
I have done the restore using the "Manipulated" ixbar
file for a full point in time restore, but did'nt have
to use the level-1, which prevents me from affirming
my opinion.
