Hello everyone,

Veeam Inline Entrophy analysis feature checks if any encryption has started on VMs. Does this feature additionally perform text analysis with onion links and AI/ML? In other words, is it enough to scan the backup it received to perform these analyses or should the guest index file be open in the relevant backup job and the credentials of the machine should be entered?

Thank you for your support. I will try to integrate these logs with the XDR product. I think I can get better results.

@tarik.yenisey -

No...inline entropy doesn’t really scan how you’re thinking. Inline scans at the “block” level, per the Guide, but rather detects “text artifacts” at that level. See link:

To get more into the file area, yes, you would need to enable File System Analysis...which yes...does require Guest Indexing to be enabled on the Jobs:

Hope that helps.

also, just FYI, per the guide:

  • Text artifacts will be detected only if the following conditions are met:
  • The block size of the file system is 4 KB.
  • Text file has the UTF-8 encoding.
  • Text file is not stored in the Master File Table (MFT).
