Snapshots and image-level backups created by jobs are not kept forever — they are removed according to retention policy settings specified while creating the jobs.
Depending on the data protection scenario, retention policy can be specified:
- In days — for image-level backups.
Restore points in the backup chain can be stored only for the allowed period of time. If a restore point is older than the specified time limit, Veeam Backup for Nutanix AHV removes it from the backup chain. Since for retention policy specified in days, the backup chain must contain at least 3 restore points, Veeam Backup for Nutanix AHV may retain restore points for a longer period than configured in the retention policy settings.
- In restore points — for image-level backups and snapshots.
The chain can contain only the allowed number of restore points. If the number of allowed restore points is exceeded, Veeam Backup for Nutanix AHV removes the earliest restore point from the chain.
