Flat backup, also known as direct backup, is a backup approach based on storage snapshots, and it's gaining popularity.
It allows users to copy data directly from primary storage to secondary storage without the use of a backup server and software.
Its major benefits are simplicity and low cost. However, the approach requires specific technologies and can't protect every resource in an organization.
Direct backup is not entirely new, either. Some vendors have supported it for years. And a number of additional vendors have gotten behind this technology recently. It has become a more viable option in recent years because of improvements in snapshots.
These products rely on redirect-on-write snapshots, which have a lower impact on performance and allow snapshots to be taken more frequently. In all cases, the systems are proprietary, and in most cases are only possible using specific systems. Because of these limitations, flat backup will not be the right approach for many organizations. But in some cases, it can be very useful.
Our Drill Down on flat backup will look at the technology in detail, explain how it works and the hardware that supports it, and discuss possible uses. It will also provide examples of when direct backup is not appropriate to help you decide whether the technology will be effective in your environment.Continue Reading

If you're using a flash-based storage system, you're familiar with caching and tiering to accelerate data. Storage tiering is used in hybrid flash storage systems to separate active and inactive data. Active data is kept on the flash tier, while inactive data is moved to a less-expensive storage tier. If the data becomes "hot" once again, it is moved back to the flash tier. Because data only lives on one tier at a time, tiered architectures need to have some kind of redundancy built into them.
In caching, data is copied or mirrored from one tier to another, so active data is on multiple tiers at the same time. If the active data is no longer needed, the cache will just create flash space for new data sets to use.
Vendors implement tiering technology in various ways. Some even have a "flash-first" approach that puts all data on flash before it is moved to a hard disk tier to become inactive. Users therefore have to be careful not to overprovision flash in these environments.
The decision to use tiering or caching depends on a variety of factors, such as the number of applications that require access to high-performance storage resources, the I/O patterns of these applications and your budgetary constraints.
Learn when to use each of these technologies in your own environment.Continue Reading
