I don't understand why?
As an IT professional, who has to manage a large number of filers, the only time I can see myself using a solution like this is if I am running out of capacity on a filer and I'm feeling too lazy to just move some files. I can’t imagine any sane storage manager using it as a permanent solution. Plus, who has time to learn and manage yet another storage tool, which we need like a hole in the head. I personally have to keep track of what is a stub on my real storage and what is real. I don’t know how I would keep track of my snapshots, backups, and archives when some of the files are stored who knows where. It just seems like a nightmare having to restore a given version of a filer or an application before I can actually restore. Oh and wouldn’t my snapshots be useless since they would no longer snap the entire storage but just a subset? How would I log the differences and manage it? Is this yet another thing we would have to manage on top of managing this on top of managing our files lol. I'm not trying to sound negative. It might be a good utility patch to overcome an emergency, But for me I just don't see how it's a long term viable solution.
Can some startup please just solve some problems that will reduce my workload rather than adding to it or my headaches and require even more of the budget I don’t have
