FAQ's
How about when doing target data deduplication on the virtual tape library (VTL) or backup appliance? Is there a similar performance impact?
has a little bit different performance impact. The knock on target-based data deduplication is that you aren't really reducing the amount of data you are sending over the network. So you are still sending the full amount of data over the network every time you do a backup. You are reducing the amount of data... More...
There were early concerns about scalability. Have manufacturers largely dealt with those concerns, or do scalability issues still remain?
take a look at how the product is architected, how to manage performance and scalability, and even data destruction on the back end. How does the product remove expired data from the index? How is the index rebuilt over time? How do you add more capacity? It really becomes a much more complex proposition at the... More...
Are there any alternatives to server-free backup that address the same problems?
no. It was the only way to do large server backups. However, the advent of CDP and near-CDP has created real alternatives to server-free backup. And, I think the large ISVs are agreeing with that. Many, if not most, of them have either acquired CDP technology or they are writing it themselves.

With a large server, I don... More...
