Hugh:

This is what the Support Technicians are telling you.
Select the option in V9.3 to Backup & Post together.
Then, when you do post, you actually have a working backup of the data from that moment.
So, if the data gets damaged or something unexpected happens, then you can just restore the data from the moment just before the post.

You can cycle through many versions of the backups, and you do not have to restore all of the Adagio data if just one module is messed up.
Ask your consultant to give you a heads-up on this feature.
