Active Full Backup

In some cases, you need to regularly create a full backup. For example, your corporate backup job may require that you create a full backup on weekend and run incremental backup on work days. To let you conform to these requirements, Veeam Agent for Mac lets you create active full backups.

When Veeam Agent performs active full backup, it produces a full backup file and adds this file to the backup chain.

The active full backup resets the backup chain. All incremental backup files use the latest active full backup file as a new starting point. A previously used full backup file and its subsequent incremental backup files remain on the disk. After the last incremental backup file created prior to the active full backup becomes outdated, Veeam Agent automatically deletes the previous backup chain. To learn more, see Retention Job for Active Full Backups.

Active Full Backup 

You can schedule a backup job to create active full backups periodically. To do this, you can use the Veeam Backup & Replication console. To learn more, see the Backup Settings section in the Veeam Agent Management Guide

Retention Job for Active Full Backups

To be able to restore data from a Veeam Agent backup, you need to have a full backup file and a chain of subsequent incremental backup files on the disk. If you delete a full backup file, the whole chain of incremental backup files will become useless. In a similar manner, if you delete any incremental backup file before the point to which you want to roll back, you won’t be able to restore data (since later incremental backup files depend on earlier incremental backup files).

For this reason, if you create an active full backup, in some days there will be more restore points on the disk than specified by retention job settings. Veeam Agent will remove the full backup chain only after the last incremental backup file in the chain becomes outdated.

For example, the retention job is set to 3 restore points. A full backup file is created on Sunday, incremental backup files are created on Monday and Tuesday, and an active full backup is created on Wednesday. Although the backup chain now contains 4 restore points, Veeam Agent will not delete the previous backup chain. Veeam Agent will wait for the next 2 incremental backup files to be created, and only then will delete the whole previous chain, which will happen on Friday. As a result, although the retention job is set to 3 restore points, the actual number of backup files on the disk will be greater for some time.

Active Full Backup 

Veeam Agent treats the active full backup in the same way as a regular full backup. If some restore point becomes obsolete, Veeam Agent will re-build the full backup file to include in it data of the incremental backup file that follows the full backup file. After that, Veeam Agent will remove the earliest incremental backup file from the chain as redundant.

There is a misspelling right here:

 

I want to let the Veeam Documentation Team know about that.
