Veeam-supported OS/File System Layer Encryption

[JS-Virt]

Hi All,

I know this is a long-shot, but there are limitations with using Veeam to back up VMs with BitLocker encryption. The main limitation is that Veeam deduplication is essentially useless and the backup files can be double in size.
Do any of you know of an alternative to encrypting/securing the OS/file system layer without causing this issue? I understand that maybe the answer is "no" because of the fundamental issue with encryption, hence why I understand that this is a long shot. But maybe there is something we can do to secure that layer without blowing out the size of the backup files? We are already using Veeam encrpytion, but our security engineer wants the OS/file system layer encrypted/secured as well.
Thanks!

Hello,
what you describe is how encryption works. It's not a limitation

If it would be different, then encryption would be useless. It must be exactly the way you describe. It expected for any VM based backup.

I see two ways to deal with it
1) use VMware encryption - but that does not align with the requirement of your security engineer (Hyper-V is different)
2) use agents inside the VMs

Best regards,
