When I first learned about Microsoft Scale Out File Server, I realized that the name was not correct, as in reality there were shared SAS jbods between the storage nodes. The main concept of a true scale-out architecture is Share-Nothing: there should be no shared component between nodes, and the failure of a component should not impact the overall storage solution. During TechED Europe 2014 in Barcelona, a new and really interesting solution has been announced, and the name is promising: Storage Spaces Shared Nothing.

Veeam Backup I/O Control and Snapshot Hunter at Tech Field Day X 2014
Veeam has always been a great supporter of Tech Field Day. As a sponsor Veeam presented several times at various TFD events, and both me and my colleague Rick Vanover have been previously TFD delegates before joining Veeam. We had another opportunity to meet Stephen Foskett and to present at TFD during VMworld EMEA 2014 in Barcelona last week. We had a 1 hour meeting and it was a really pleasant meeting as always. This time, we used our slot to talk a little bit more in details of two new upcoming features in Veeam Backup & Replication v8.

The new backup mode in Veeam Backup & Replication v8
When it comes to choosing a backup mode in Veeam Backup & Replication,there is a constant trade-off between space efficiency and I/O efficiency. Forward mode is I/O efficient, while Reversed is space efficient. The new method coming in v8 will combine the pros of each, to offer an even better backup experience.

Pros and cons of storage snapshots as a data protection solution
In one of my presentations for the VeeamON conference, titled The Quest for the Ultimate Backup Storage Architecture, I will explain how a tiered approach to data protection is the best solution to have an effective protection in place, and I will describe the different layers of data protection that can be applied to a production environment, and the layer I thought about for the most of the time was Storage Snapshots. After some thinking, I labeled it as a Tier-0 level, with specific pros and cons that should be carefully evaluated to properly use them in a data protection scenario.

Erasure Coding: the best data protection for scaling-out?
I’ve always been a fan of scale-out storage solutions, and I’ve always preached about them.
As data is skyrocketing, the best viable way to cope with this growth is having a system that can be scaled accordingly without the pain of data migrations involving TBs of data. One of the limits of scale-out systems however has always been the data protection techniques applied to them. RAID is inefficient, replication is too expensive, so what about Erasure Coding? Is it mature enough to become the new data protection technique for storage systems?
