Assets by policy type
NetBackup supports MS-Windows, NAS-Data-Protection, and Standard policy types for malware scan. The following section describes the procedure for scanning NAS-Data-Protection backup images for malware.
Each NAS volume or share is read over NFS or SMB, and backed up using a configured number of backup streams. The maximum number of streams per volume determines the number of backup streams that are created to back up each volume. For example, consider a policy that contains 10 volumes and the maximum number of streams is 4. The backup of the policy creates 4 backup streams for each volume, with a total of 40 child backup streams and 10 parent backup streams.
Note:
The number of scans depends on the number of batches that were created to perform the scan. Only the parent stream backup image is visible on the Malware detection UI.
For more information on multi stream backups, refer to NetBackup NAS Administrator's Guide.
To scan the supported assets by policy type, perform the following:
- On left, click Detection and reporting > Malware detection.
- On the Malware detection page, click Scan for malware.
- In the Search by option, select Assets by policy type.
- From the Client/Asset table, select a Client/Asset to scan.
- Click Next.
If the selected client in the previous step supports multiple policy types, you can select a single policy type for scanning.
- For the Start date/time and End date/time verify the date and the time range or update it.
The scan is initiated for a maximum of 100 images.
- In the Scanner host pool, Select the appropriate host pool name.
- In the Volume field, Select volume backed up for NAS devices.
Note:
Volume level filtering only fetches top-level directories of the NAS-Data-Protection volume backup. Volume level filtering is applicable only if the top-level directory is a volume. In such case, user has the option to select individual backup images by using the Backup images option in the Search by option.
- From the Current status of malware scan, select one of the following:
Not scanned
Not infected
Infected
All
- Click Scan for malware.
Warning:
There are more than 100 images in your search. Unable to scan more than 100 images. Adjust the date range and try again.
- After the scan is initiated, the Malware Scan Progress is displayed. The following are the status fields:
Not scanned
