Reduce scan time in custom Windows VM

Keep custom VM clones running to reduce scan time.

To reduce the scan time in a custom Windows VM:

1. Go to the Azure Config page
2. Click Configure Wizared and enable Allow Hot-Standby VM.
3. Click Submit. After Allow Hot-Standby VM is enabled, FortiSandbox will perform vminit again to apply changes to existing custom VM clones or prepare new clone(s).

   

4. After vminit done, go to the Azure portal to check that the clone(s) are have kept running with /without a scan job. Allow 2-3 minutes for a custom VM clone to restore status after a scan job done. Aftwerwards, the clone will keep running and standby for the next scan job to reduce VM scan time.

It is highly recommended that enabled clone number is double or more than incoming scan jobs number. Ensure clone(s) are keep running in the Azure portal before submitting scan jobs.

Example 1: Scan two files/urls at the same time

To scan two files/urls at the same time in windows 10x64 custom VM, it's best to have 4 running clones of Windows 10x64 custom VM.

Example 2: Scan files in a compressed file or text file

To scan files in a compressed file or urls in a text file, it’s best to count the total number of files/urls before enabling the custom VM clone number. If there are 6 files included in a compressed file and you are forcing them to scan in windows 10x64 custom VM, you should enable a minimum of 12 clones windows of 10x64 custom VM. After vminit is complete, go to the Azure portal, and confirm that all 12 clones are running , and then submit the scan file.

Example 3: Scanning more files

If you are already scanning files/urls and need to scan more files/urls, wait until the previous jobs are completed, and custom VM clone(s) is/are restored completely. Afterwards, confirm the clones are running from the Azure portal. If all clones are restarted and running, you can submit new jobs with good performance of custom VM.
