Len/Wayne,
We do nightly fulls with hourly logs (incrementals) 8am-8pm. Our
Exchange admins do a fair amount of restores, and appreciate having an
RPO of 1 hour instead of 24 hours. If your company is willing to lose
24 hours worth of email, I wouldn't worry about it - stick with fulls.
But I can just about guarantee that will change the first time it
actually happens.

The reasons I have been given are:
1) The use of the incremental logs add complexity to the job for the
person doing the restore, and sometimes a step is forgotten.
2) The full backups do a checksum on all the data base pages that are
backed up via the online api. An incremental backup does not read any of
the data base pages, so it will not find any problem pages, if they
exist.
3) Replaying the logs, can add time to the restore. This depends on the
speed of your hardware and the quantity of the logs.

We just implemented the TDP for exchange. Our exchange admin just got
back from Microsoft exchange class and is being told to only perform
full backups of Exchange. She has been warned that incremental are not
reliable with exchange will just cause us problems. I can't see why...
Worked ok for us during testing.
Does anyone know of any problems with the full/incremental strategy?
Have you ever had problems recovering exchange using the TDP with
full/incremental
Thanks,
Wayne
