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
as backup targets. Storage space is finite, which can limit the allowable retention period for data. Data reduction technologies like data deduplication and delta differencing can dramatically extend the effective storage capacity. Also, indexing and search are can be valuable when rapid file organization and location are needed. Below are a series of best...

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
What happens if you fill up a storage system with deduplicated data and it needs to grow?
This is really the Achilles heel of data deduplication right now.
If you have a lot of growth and wind up filling up an entire system, most products on the market today don't have the ability to add another system behind it. So, you have to invest in a new system. And that leads to... More...
What is server-free backup, and how does it work?
this is accomplished, and they generally have an alternate copy of the data, such as a business continuous volume (BCV) or a split-mirror, or perhaps a snapshot, and then present that data to some other system or device that can copy the data to tape. The typical way that this is done is via a dedicated backup...

What are the benefits of using a virtual tape library (VTL) for data deduplication?
Well, there are a few big use cases right now that are driving data deduplication to the forefront of the decision-making that's going on in backup environments. The bottom line is data deduplication is dramatically changing the economics of using disk as a backup target as opposed to tape. You...
