Configuration for scan instances
The traditional malware scan using Instant Access is based on vpfsd instance. NetBackup 10.3 and later uses a separate vpfsd instance for malware scanning which is configurable. This configuration is done using the parameter. By default, malware scan uses one instance. In most cases, scan instance is adequate but increasing the number of scan instances improves scan performance, although it also requires more CPU and memory. You can increase the number of scan instances from 1 to 4 and distribute the malware scan shares cross all the scan instances.
To change the number of scan instances
- Stop NetBackup on the media server using the following command:
systemctl stop netbackup
Or
/usr/openv/netbackup/bin/goodies/netbackup stop
- Modify the number of scan instances as follows:
Change the value of numOfScanInstance parameter in the
vpfsd_config.jsonfile. The value must be an integer between 1 and 4.For example:
# grep numOfInstance /msdp/vol1/etc/puredisk/vpfsd_config.json
BYO (build-your-own): <storage path>/etc/puredisk/vpfsd_config.json
NetBackup Appliance and NetBackup Flex Scale: /msdp/data/dp1/pdvol/etc/puredisk/vpfsd_config.json
NetBackup Flex: /mnt/msdp/vol0/etc/puredisk/vpfsd_config.json
- Modify the number of vpfsd instances (numOfInstance), the value must be an integer between 2 and 16. Ensure that the value of numOfInstance is greater than numOfScanInstance.
- Start NetBackup on the media server using the following command:
systemctl start netbackup
Or
/usr/openv/netbackup/bin/goodies/netbackup start
Note:
Malware scan instances are part of vpfsd instances, which are reserved only for malware scanning.
