Disaster Recovery to AWS Always-on, near-synchronous replication unlocks RPOs of seconds and RTOs of minutes, radically reducing data loss and downtime. Up to 25 VM : - Zerto CDP engine uses unique journaling technology to track all changes that occur on any protected workload. - You can use that journal data to recover to any point in time with seconds of granularity. - Flexible Journal with retention from one hour up to 30 days. - The intuitive interface and management plane orchestrates and automates operations with simplicity. As part of protection to AWS and general DR, Zerto creates EBS volumes that contain the data that existed on the matching disk of the production VM for the checkpoint that was chosen for recovery. The EBS volumes are created and filled with data that was previously replicated from the production site and saved to S3 blobs.
