Is Archive Manager attachment store supported with Windows Server 2012 R2 Deduplication?
Do we support an attachment store using Windows Server 2012 R2 Deduplication with Archive Manager?
It would appear this technology is chunk level (or block level) deduplication and there may be some level of space saving gained by using that. Mostly useful in very specialized scenarios.
Further information is on the following Microsoft link:
Archive Manager already only stores a single instance of an attachment and using Archive Manager with Windows Server 2012 R2 Deduplication, it wouldn't reduce storage that much.
We calculate an MD5 hash of the file and if two files match, we discard the duplicate and reference the original.
Unfortunately we don't provide support for it, nor have we tested it.
Being that this is a Windows feature; maybe the volume would show up as a standard drive, meaning technically you could use it with Archive Manager.
