[Burp-users] VSS support and encryption software

[<alb...@la...>]

Hi all 

I wanted to let you know I had a problem using Burp Backup (and any backup software relying on VSS) in encrypted non-system partitions with TrueCrypt or VeraCrypt, because it cannot use VSS when the encrypted partition is a non-system one (for example when you have 2 or more hard drives and you want full encryption of all drives, and backup all of them) 

and I read the TrueCrypt/VeraCrypt the documentation, and they say : 

"The Windows Volume Shadow Copy Service is currently supported only for partitions within the key scope of system encryption (e.g. a system partition encrypted by VeraCrypt, or a non- system partition located on a system drive encrypted by VeraCrypt, mounted when the encrypted operating system is running). Note: For other types of volumes, the Volume Shadow Copy Service is not supported because the documentation for the necessary API is not available."

this is the same for TrueCrypt 

and maybe for other encryption software, did you have a feedback on it ? 


I don't know either what happens for non-encrypted other Windows filesystems that we would backup, 
for example, is it possible to backup FAT32, exFAT or SMB volumes, USB drives ? does VSS apply ? 


so the question is : 

It would be really useful for all theses cases if we could desactivate VSS support for some drives to allow Burp Backup to work even on desktop/laptops protected by encryption 

As for the moment, in these cases, we only have the choice to backup OR encrypt 

Thanks a lot for this great piece of software 

Best regards.
