What feature provided by OceanStor Dorado is used for high-frequency data protection (snapshot in seconds)?

HyperCDP (Continuous Data Protection) is a feature specifically designed for high-density, high-frequency data protection in Huawei OceanStor Dorado systems. While standard snapshots (HyperSnap) have limits on the total number of point-in-time copies and the frequency at which they can be taken, HyperCDP allows for the creation of snapshots at intervals as short as several seconds.

HyperCDP achieves this by utilizing a specialized metadata management system that minimizes the impact on system performance during the snapshot creation process. It can support up to 60,000 recovery points per LUN, providing a much finer granularity for data recovery than traditional backup or snapshot technologies. This is particularly useful for protecting against ransomware or logical data corruption, as it allows an administrator to roll back a database or volume to a state just seconds before the incident occurred.HyperReplication (Option B)is for remote DR,HyperLock (Option C)is for WORM/compliance, andHyperVault (Option D)is an integrated backup tool for older hybrid systems.
