VM snapshots are created automatically by the replication process as quickly as every 5 minutes (as long as the previous snapshot’s change blocks have been fully replicated to the target HC3 cluster). The remote replication default schedule will take a snapshot every 5 minutes and keep snapshots for 25 minutes.
ScaleCare Support recommends a snapshot frequency of 15 minutes as a general best practice.
