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.

NAS-Data-Protection

Each NAS volume or share is read over NFS or SMB, and backed up using a configured number of backup streams. Maximum number of streams per volume determines the number of backup streams that are deployed for backing up each volume. For example, if a policy contains 10 volumes and the value of this parameter is set to 4, then a group of 4 backup streams for each volume is seen, thereby total of 40 child backup streams and 10 parent backup streams as part of backup execution of the policy.

Note:

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.

On left, click Detection and reporting > Malware detection.
On the Malware detection page, click Scan for malware .
In the Search by option, select the Assets by policy type.
Select the Policy type as NAS-Data-Protection.
Select the Copies as Copy 2.
From the Client/Asset table, select a Client/Asset to scan.
Click Next.
Note:
If the selected client in the above step supports multiple policy types, then user has an option of selecting a single policy type for scanning.
For the Start date/time and End date/time verify the date and time range or update it.
Note:
According to selection criterion, scan gets initiated to 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.
Once the scan is initiated, the Malware Scan Progress is displayed on Malware Detection page. Following are the status fields:
- Not scanned
- Not infected
- Infected
- Failed
  Note:
  When we hover on failed status, the tool tip displays the reason for failed scan.
  The backup images which failed in validation, are ignored. Malware scanning is supported for backup image stored on MSDP storage with instant access capability for the supported policy type only.
- Pending
- In progress

Note:

Ensure that you select the Malware scan status option as All to scan the NAS-Data-Protection backup images created on earlier version of NetBackup media server.
