Wolfgang,

You are correct, to restore an Exchange server you need,
ONE of the following:
   1 Full backup (already has the logs it needs to recover)
      or
   1 Full backup + NN incremental backups
      or
   1 Full backup + 1 latest differential backup
This is covered in Chapter 1 of the TDP for Exchange book under
a section titled "TDP for Exchange Backup Strategy Considerations"

TDP for Exchange version 2.2 will always keep the latest
FULL backup until another FULL backup is completed succesfully.
It will NOT expire any INCREMENTAL or DIFFERENTIAL backups that
go with the latest FULL backup until the next FULL backup
is completed succesfully.

I hope that helps.

Thanks,

Del
