Hi, you're right, that option would be a good solution unfortunately, last time I've tried it, I didn't manage to make it work, because Graham said it seems that the function tries to initialize VSS first, which fails, before excluding a drive letter so in fact you have to be sure that VSS works to be able to disable it (which is not my case) we talked about it on a older message here : https://sourceforge.net/p/burp/mailman/message/35388142 Graham said ( 2016-09-29 ) : "Hello, I think that extra work needs to be done on burp to make this work properly. I see the code tries to run g_pVSSClient->InitializeForBackup() before checking the drive letters to snapshot, so in your case, setting the drive letters doesn't help. The code is in src/client/cvss.c. You could try bypassing that code completely and rebuilding the Windows client to see if you can get further. Or you could ask me to do the change, test it, and put it in a future version, but I probably won't get around to it for a while. See this page for a more detailed explanation: http://burp.grke.org/requests.html " I don't know what he want to do about it Thanks for your advice anyway, and if you all have feedbacks about full disk encryption and best practices for burp backup and heterogeneous computers, I'll be glad to hear your hints and advices too Best regards ----- Mail original ----- De: ma...@me...

Does this quote from man solve your problem? " vss_drives=[list of drive letters] When backing up Windows computers, this option allows you to specify which drives have VSS snapshots taken of them. If you omit this option, burp will automatically decide based on the 'include' options. If you want no drives to have snapshots taken of them, you can specify '0'.
