About dynamic scan
For malware scanning on Standard, MS-Windows, NAS-Data-Protection, Cloud, Cloud-Object-Store, Universal shares, Kubernetes, VMware and Nutanix AHV workloads, NetBackup 10.3 or later provides support for feature.
This feature provisions all files in the backup images on demand unless the file is accessed and read or there is no overhead on the file's provisioning.
In comparison to malware scan using Instant Access mount points in NetBackup versions prior to 10.3, dynamic scan optimizes instant access and scan performance for MSDP (for large number of files in the backup). This improves the instant access time as well as the scan performance.
NetBackup Media/Storage server 10.3 or later supports Instant Access on OST target volumes backup for malware scanning, and support malware scanning for big ADS information.
For MSDP storage, dynamic scan feature is applied on platform BYO, NBA, Flex, Flex-worm, FlexScale, Azure Kubernetes Services Cluster / Amazon Elastic Kubernetes Cluster.
For OST and Advanced Disk storage, dynamic scan feature is applied only on platform BYO, NBA and Flex appliance.
