Active Full Backup
In some cases, you may need to regularly create full backups. For example, your corporate backup policy may require that you create full backups on weekends and run incremental backups on work days. To let you conform to these requirements, Veeam Backup for Nutanix AHV allows you to create active full backups (either manually or automatically according to a specific schedule).
To create an active full backup Veeam Backup for Nutanix AHV retrieves VM data from the source cluster where the VM resides, compresses and deduplicates it and writes it to the VBK file in the backup repository. When creating an active full backup, Veeam Backup for Nutanix AHV starts a new backup chain for the VM. All further created incremental backups use the latest active full backup file as a new starting point. The old full backup file from the old backup chain remains on disk until it is automatically deleted according to the retention policy.
Veeam Backup for Nutanix AHV triggers a backup job to create an active full backup even if a regular backup session is not scheduled on this day. The active full backup session starts at the same time when the backup job is scheduled. For example, if you schedule the backup job to run at 12:00 AM Sunday through Friday, and schedule active full backup to be created on Saturday, Veeam Backup for Nutanix AHV will start a backup job session that will produce an active full backup at 12:00 AM on Saturday.
If the backup job is not scheduled to run automatically or is disabled, Veeam Backup for Nutanix AHV will not perform active full backup. If a regular backup session and an active full backup session are scheduled on the same day, Veeam Backup for Nutanix AHV will produce an active full backup only. However, if you run the backup job again on the same day manually, Veeam Backup for Nutanix AHV will perform incremental backup in a regular manner.
