High-frequency snapshots allow you to schedule recurring snapshots as frequently as every 30 minutes, and as a preview feature, you can schedule snapshots every 15 minutes.
To enable high-frequency snapshots, your protected site must be running vSphere 7.0 Update 3 or higher, and your protected SDDCs must be running version 1.16 or higher. For the latest release information on vSphere 7.0 Update 3, see these product release notes.
Leveraging a unique data capture technology that is different than VMware's vStorage APIs for Data Protection (VADP) and VMware vSphere replication, high-frequency snapshots create a consistent snapshot of a protected workload by extracting only the delta between two consecutive snapshots and only applies the changes to new snapshots.
High-frequency snapshots are also not dependent on VM-level snapshots to ensure consistency, are not bound by snapshot hierarchy on disks, and are not affected by the impact of consolidating snapshots at the end of the sync process. These capabilities enable high-frequency snapshots to take as many as 48 snapshots per-day (every 30 minutes).
High-frequency snapshots also support quiescing, so you can take snapshots that first pause the state of running processes on the VM to guarantee a consistent state of any applications running at the time a snapshot is taken. For more information, see App-consistent Snapshots with Quiescing.
