Anyone seriously considering de-duplication technologies should look
at the series of articles at
<http://www.backupcentral.com/content/view/175/1/> written by Curtis
Preston (author of the O'Reilly books "Unix Backup & Restore", the
2nd edition "Backup and Restore" which covers Unix and Unix-like OSes
as well as others, and "Using SANs and NAS").

Keep in mind that a lot depends on the kinds of other tools you're
using. For example, in a TSM "incrementals forever" type of
environment, the fact that you're taking only incremental backups
means that you're effectively doing a lot of de-duplication on the
input side, and further de-duplication is not likely to buy you as
much. See <http://www.backupcentral.com/content/view/136/47/>.
