Components of Integrated Data Protection Toolkits
Components of integrated data protection toolkits
Whether implemented as standalone software or integrated into HA software, CDP provides the easiest and most effective protection against the loss of critical business data. However, CDP alone is insufficient to meet organizations' data protection needs. This is because the CDP data store typically does not hold all of the organization's data but only contains data updates.
Furthermore, organizations often reduce storage requirements by purging updates older than a certain age. If they did not do so, storage needs would grow rapidly and endlessly because the CDP data store contains all updates rather than simply a copy of current data.
Consequently, the CDP data store alone is insufficient to recover all of an organization's data after a disaster. This makes it necessary to first load databases and files from the most recent backup tape so they can be brought up-to-date using the CDP data store.
Another shortcoming of CDP alone is that it cannot be used to keep a business running when a production server needs to be taken offline for maintenance. This is because CDP maintains a store of data updates, not a replica server. In fact, the CDP server may run on a different platform (for example, a low-cost Windows or Linux-based server) than the production server, which might be an IBM i-based system. Thus, when the primary server is offline, CDP does not provide a ready-to-run backup server. On the other hand, HA technology does provide this facility.
Therefore, while CDP fills the data protection gap left by HA and DR tools and tactics, all three technologies are vital components in any data protection strategy. They complement each other to provide the complete data protection solution organizations need today.
