DAOS = Domino Attachment and Object Store, a neat technology we have been using for the last decade or so primarily in a huge document and email database. DAOS effectively de-duplicates attachments and objects over a certain size by replacing them with links to an object store (e.g. so instead of storing 23 identical copies of a 10Mb file attachment it stores 1 plus 23 links). It has saved us humungous amounts of disk space.
Now we need to migrate our stuff to a Microsoft platform and they don’t seem to have anything similar…. or do they?
