Appendix I : Continuous Data Technology 297
Appendix I Continuous Data Technology
Overview
These days, the paper-less revolution, corporate governance, business ethics and
regulatory compliance have all led to a tremendous influx of digital data. Safekeeping
and management of stored data has, therefore, assumed supreme importance. Various
new technologies are emerging in an attempt to offer an appropriate solution to address
these requirements. Statistics show that data growth is almost doubling every year, yet
the Recovery Time Objective (RTO) has remained the same, if not tighter. From the
anatomy of data re-usage, it is clear that in overwhelming situations most recent data is
recalled.
This immediacy of need and the corresponding instances to data reference steadily
decline as the data ages. Continuous Data Protection (CDP) is now assuming utmost
importance and is no longer an industry buzzword. CDP, which deals with backup and
restore, is probably the most important aspect of “Continuous Data Technology” (CDT).
More than just recovery, CDT virtually handles any act of granular copy-creation in the
enterprise. With this technology, granular instances of chronologically ordered data can
be used to serve potentially a wide range of applications and not merely backup and
recovery. Some of these are CDR (CDT for Replication) and CDI (CDT for Data Images).
StorTrends iTX 2.7, with up to 2,000 snapshots per volume (Near-CDP recoverability)
and an efficient I/O journaling architecture (Full CDT), offers the solution, providing a
snug hand-and-glove fit for the business need.
