How to implement snapshots
recovering files that they're not authorized to access.
Integrate snapshots into the broader data protection scheme Evaluate the importance of your snapshots and determine the level of data protection that is appropriate for your snapshot data. RAID 5 or even RAID 6 protection is usually adequate in the snapshot storage system itself, while some organizations take it... More...
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
Use data backup tools to locate bottlenecks Experts point to a growing number of backup and data protection management tools that can analyze backup traffic and highlight potential problem areas. For example, you might identify tape as your data bottleneck and spend significant capital dollars for upgrades and other changes -- only to discover that the problem was... More... FAQ's
Server-free backup FAQ
the only way to do large server backups. However, the advent of continuous data protection (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... More...
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...
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.
