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 spite...

FAQ's
Which data deduplication appliances and backup software do you view as enterprise ready?
If you have 20 TB of data to backup, I would say most data deduplication appliances on the market today can handle that without too much of a problem. When you start scaling to 50 TB, 100 TB, 1 PB of backup data, the dynamics really change. You have backups going...

Are there any alternatives to server-free backup that address the same problems?
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't have enough time in the day or enough CPU cycles to back up... More...
We're hearing a lot about forward-referencing deduplication and backward-referencing deduplication. Can you talk about what that means exactly?
backup as a result is really going to have a lot of pointers back to older data. So when you "redupe" the data back to its original state, you're going to be going back and pointing to lots and lots of pointers because you have a reverse-referencing-type methodology.
Forward referencing is kind of the opposite and... More... |
