Timely, concerning some of the discussions on DAOS in the blogosphere, searchDomino writer Mike Kinder has posted an article on DAOS, based on Paul Mooney's session at Lotusphere 2009. In addition to reporting on the disk savings and the underlying architecture, Mike provides you with some points to consider:

Caveats to be aware of before implementing DAOS
There are also some things that must be aware of before implementing DAOS:
- Your backup process must change. When attachments are initially stored in the OS, the directory of NLO files needs to be backed up, in addition to the databases on the Domino server that you were backing up before. When performing the backup, it's a good idea to back up your databases first, then the NLO files.
If you back up the NLO files first, but a new message comes in with an attachment later, it is possible that the email would be backed up, but the related NLO would not.
- If copying/replicating a DAOS-managed database from one server to another (or to a client) where DAOS is not enabled, the attachments are re-added to the NSF, so it will be much larger. Make sure that the new destination has the necessary disk space to handle the database with all of the attachments added in.
- NLO files should not be copied (at the OS level) from one server to another. The files are encrypted by the Domino server ID. If they are moved to another server where a different server ID file is used, the NLO files are useless.

Are .nlo files always encrypted? I thought this part was optional?
