How to implement snapshots
(RPOs) by supporting more frequent recovery points. When properly implemented, snapshot data can be used to restore lost files or recover from more substantial data loss. Features like data deduplication are also appearing in snapshots to reduce disk storage requirements, allowing for many more snapshots and longer retention periods. Below are a series...

How to implement disk-to-disk backups
more frequently. Disk offers far better performance than tape systems, allowing for faster data transfers as well as greater long-term reliability. Disk can accept complete backup volumes, as well as simple file copies. For example, backup software can send a full backup volume to a virtual tape library (VTL) emulating the behaviors of a traditional tape system...

How to improve tape backup performance and reliability
The role of tape is clearly changing, shifting away from everyday data backup and moving toward deep archiving or offsite storage, but tape is still an important element of many data centers. Storage professionals must contend with concerns about tape performance and reliability that have remained almost unchanged for decades. In...

FAQ's
Are there any instances where data deduplication will not provide any benefits? Superior benefits?
a lot of new images being created, then you'll see very little benefit from data deduplication. In that case, you're better off just running differential or incremental backups.
As far as areas in which data deduplication can provide superior benefits, databases have a lot of redundant data and... More...
How does data deduplication affect the backup process in a virtual server environment?
I'm hearing more and more questions about data deduplication and virtualization. And, it's not just server virtualization, another area is desktop virtualization. With server virtualization, you have lots of virtual machine images out there and they have the same operating...

What type of data reduction ratios should you realistically expect using deduplication?
There are two ways you can look at it. Most people are looking at data deduplication in conjunction 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.
