View the backup overview

On the NAS Backup page, select Alibaba Cloud NAS. Select a region at the top of the page to view statistics for backup resources and backup point virus scans in that region. The following table describes the metrics.

Category	Metric	Description	Example
Backup resource statistics	Backed up NAS	The total number of General-purpose NAS file systems that have at least one backup point. This count includes released file systems that still have backup points. It excludes file systems that have a backup plan but no backup points yet. Only General-purpose NAS file systems are counted.	Assume you have 12 NAS file systems in the current region. 5 have backups activated and have generated backup points. 3 have backups activated but have not yet generated backup points. 4 do not have backups created. The statistics are shown as follows: Backed up NAS: 5 Not backed up NAS: 7 The 3 NAS file systems that have backups activated but no backup points are counted as "Not backed up NAS". After backup points are generated, they are automatically categorized as "Backed up NAS". The statistics will then be: Backed up NAS: 8 Not backed up NAS: 4 Released NAS file systems that still have backup points for recovery are also counted as "Backed up NAS".
	Not backed up NAS	The total number of active General-purpose NAS file systems that have no backup points. This includes file systems where a backup plan is active but no backup points have been created. This can happen if a backup has not run yet, backups consistently fail, or existing backup points expired after the plan was paused. Only General-purpose NAS file systems are counted.
Backup point virus scan	Total backup points scanned	The total number of backup points that have been scanned.
	Total files scanned	The total number of scans performed across all files and the number of files classified as high-risk, medium-risk, low-risk, and safe. This number is the basis for virus scan billing. A single file might be scanned multiple times depending on your operations.
