You need to be able to go back in time and restore the uncorrupted data. And if your backup is offsite, that is even better.

If your A site becomes corrupted for any reason, it\u2019s going to be replicated over to your B site, possibly instantly, and if you don\u2019t have a backup copy, you could be in a lot of trouble. For most organizations, data corruptions can go undetected for a long period of time (weeks or months), and CDP is a very expensive option to rely on for backup because of the sheer volume of data points to comb through to find the proper restoration point. However, continuous data protection is a solid replication option, and combined with offsite backup can help build a robust disaster recovery plan.<\/p>\n<p>True continuous data protection, while becoming more and more popular, is also expensive, so unless you require an RPO of minutes, or even seconds, near CDP is still a fine method that can work well for your organization.<\/p>\n<p>Continuous data protection is only one component of your overall <a href=\"https:\/\/otavawebsite.wpengine.com\/solutions\/data-protection\/disaster-recovery-as-a-service\/\">Disaster Recovery<\/a> plan, and <a href=\"https:\/\/otavawebsite.wpengine.com\/solutions\/data-protection\/disaster-recovery-as-a-service\/\">Disaster Recovery as a Service<\/a>.
