Zimbra NG Modules/Zimbra NG Backup/Smartscan

Zimbra NG Backup - Smartscan

What is the Smart Scan?

The Smart Scan is the main coherency check for the health of your backup system. It's "Smart" because it operates only on accounts modified since the last SmartScan, hence improving system performance and decreasing scan time exponentially.

By default a SmartScan is scheduled to be executed each night (if "Scan Operation Scheduling" is enabled in the Zimbra NG Backup section of the Zimbra NG Modules Administrative Zimlet). Once a week, on a day set by the user, a Purge is executed together with the SmartScan to clear Zimbra NG Backup's datastore from any deleted item that exceeded the retention period.

How does it work?

The Zimbra NG Backup engine scans all the items on the Zimbra Datastore looking for items modified after the last SmartScan updating any outdated entry and creating any item not yet present in the backup while flagging as deleted any item found in the backup and not in the Zimbra Datastore.

Finally, it updates all Configuration metadata in the backup, so that Domains, Accounts, COSs and Server Configurations are stored.

When is a Smart Scan executed?

When the Zimbra NG Backup module is started.
Daily, if the Scan Operation Scheduling is enabled in the Zimbra NG Modules Administration Zimlet.
When the Real Time Scanner is re-enabled via the Zimbra NG Modules Administration Zimlet after being previously disabled.
