[Burp-users] Windows: is VSS feature optional?

[Sven E. <sv...@eh...>]

Hello,

I am sorry if this has been answered before, I cannot find good
information about that.

Is it really possible to switch off VSS snapshots (version 1.4.40,
protocol 1)? I should do so to not interfere with a second backup
process. I put the option "vss_drives = 0" in both server and client
configuration, but in the backup console log, it seems like this is ignored:

Please, what is the status of the VSS feature? If it can be switched
off, how?
