In this third and final installment, we examine the various methods of data protection, and come back to our favorite topic, testing…
Methods of Data Protection
This brings us to the issue of choosing data protection technologies. If you have one of the rare, homogeneous environments, this can be a straightforward matter, as simple as using the replication technology available with your virtualization platform of choice, like VMware’s Site Replication Manager.
More typical data centers with physical and virtual servers, Windows and Linux, and so forth, will need a replication solution with broad OS and application support, like FalconStor’s data protection solution, with host agents for a wide variety of systems. Look for a solution that can do frequent snapshots, as this will determine the recovery point objective (RPO) that’s possible. Any solution can offer a 4-hour RPO, but 15-minutes is the new gold standard, so do your research.
