How to implement snapshots
It can take up to 12 hours or more to process a full backup job and move the entire backup volume to tape or disk. For many companies, that's just too much time. IT departments can use snapshots to capture entire storage environments, or simply track changes to the state of mission-critical systems. Snapshots can establish recovery points in just a fraction of the time... More...

FAQ's
How about when doing target data deduplication on the virtual tape library (VTL) or backup appliance? Is there a similar performance impact?
It 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 that you store, but there is... More...
What type of data reduction ratios should you realistically expect using deduplication?
with backup; backup appliances performing deduplication or even virtual tape libraries (VTL). So, looking at it in that context, you'll hear advertised ratios of anywhere from 10 to 500X.

But, realistically, I think it's safe to assume a ratio of anywhere between 13 to 17X. You'll probably see lower ratios on target... More...
