The Backup Purge is a cleanup operation that removes from the Backup Path any deleted item that exceeded the retention time defined by the Data Retention Policy.
The Purge engine scans the metadata of all the deleted items and when it finds an item marked for deletion whose last update is older than the retention time period, it erases it from the backup.
Note however, that if an item BLOB is still referenced by one or more valid metadata files, due to Zextras Backup’s built-in deduplication, the BLOB itself will not be deleted.
Customizations backed up by Zextras Backup also follow the Backup Path’s
purge policies. This can be changed in the
`Zextras Backup section of the
Administration Zimlet by unchecking the
Purge old customizations checkbox.

With infinite retention active (i.e., the Data Retention Policy is set to 0), the Backup Purge will immediately exit since no deleted item will ever exceed the retention time.
