Tape Elimination (VTL and encryption)
Many of our customers are modernizing backup architecture, with the goal of minimizing or even eliminating tape. Mitigating media loss risk, simplifying operations, and improving disaster recovery are key drivers for tape reduction in core and remote backup environments. Many customers are embracing VTL and deduplication/replication as an outright alternative [...]

Archiving
Should backup and archive be the same service? The GlassHouse general position is ‘no’, however every environment faces need for long term retention of data, and in lieu of a true enterprise archiving platform, backup data retention is the only option for many enterprises. In general, we see tape playing a valuable role for long [...]

Data replication and DR solutions
The impact of disk based replication of deduplicated data has a profound impact on backup architectures and their role in disaster recovery. The traditional backup environment today uses offsite vaulting for tape, and disk or host based replication for more aggressive disaster recovery capabilities. The role of backup in disaster recovery [...]

Data Deduplication

Data deduplication is one of the most disruptive technology features to affect enterprise backup. This technology feature makes disk economical for backup data storage, and opens up options for remote site and core data center replication, previously unavailable. Software and hardware based deduplication have distinct differences in terms of scale/performance/capacity, and should [...]

VMWorld 2009
All this week at VMworld 2009 we have been discussing the cloud. Since VMworld is mostly about infrastructure we have been discussing the internal, external and private cloud concepts from an infrastructure point of view. Of course the real value I see coming from the cloud paradigm is for application and application service levels.
Eventually, [...]
