Zimbra NG Backup - Purge

What is the Backup Purge?

The Backup Purge is a cleanup operation that removes from the Backup Path any deleted item which exceeded the retention time defined by the "Data Retention Policy".

How does it work?

The Purge engine scans through the metadata of all deleted items, and removes any item whose last update (deletion) timestamp is higher than the retention time.

Should an item BLOB still be referenced by one or more valid metadata files - due to Zimbra NG Backup's built-in deduplication - the BLOB itself will not be deleted.

Zimbra NG Modules comes with Postfix Customizations backed up by Zimbra NG Backup also follow the backup path's purge policies: this can be changed in the "Zimbra NG Backup" section of the Zimbra NG Modules Administration Zimlet by unchecking the "Purge old customizations" checkbox.

When is a Backup Purge executed?

  • Weekly, if the Scan Operation Scheduling is enabled in the Zimbra NG Modules Administration Zimlet.
  • When manually started either via the Zimbra NG Modules Administration Console or the Zimbra NG Modules CLI.

"Infinite" retention

Should the "Data Retention Policy" be set to "0", meaning infinite retention, the Backup Purge will immediately exit since no deleted item will ever exceed the retention time.
