How PD Snapshot Job Works
When you start a PD snapshot job, AHV Backup Proxy uses Nutanix REST API to send a command to create a PD snapshot to AHV cluster.
After every successful snapshot job session, AHV Backup Proxy creates a new restore point. If AHV Backup Proxy detects that the number of restore points in the snapshot chain exceeds the retention limit, the earliest restore point is removed from the chain. Retention policy is set at the Schedule step of the New Job wizard.
Every 60 seconds AHV Backup Proxy synchronizes with Veeam Backup & Replication and sends data on new or deleted snapshots.
