Clearly, I am not the only one interested in backup or even blogging about it.  So…I guess it is not perfectly accurate to say “The Backup Blog” – in fact, there is another blog, from Scott Waterhouse, that is called “The Backup Blog” – and he even works for VMWare.  So, he gets enterprise credit, where I may not.
Anyway, he does a good job, so check out articles like this one about de-dupe at “The Backup Blog” at Scott’s Typepad blog site.
