Mount one volume ID from 2 possibilities by command line

[ragnolor]

Hi,

I have this situation: 2 HDD (encrypted) will be used to do weekly backups. They will take turns like this: first week is HDD A, second week HDD B, third week HDD A again, and so on...

What I need is a VeraCrypt command line to include the two devices IDs and if the first ID is not phisically connected it go ahead and try the next volume ID:

Supposing \?\Volume{ID.of.HDD.weekB is the currently connected device ID on the server:

veracrypt.exe /volume \?\Volume{ID.of.HDD.weekA}\ /letter h /password "123456" - and VeraCrypt says.."ok, this one is not connected.. trying the next volume.."

veracrypt.exe /volume \?\Volume{ID.of.HDD.weekB}\ /letter h /password "123456" - and then the volume is successfully mounted!

Is this possible?

Which version of Veracrypt are you running?

1.21 RC4

I don't see how you could do it with one command line, but a simple batch file eg 'mount.bat' could do it:

@echo off
if exist \\?\Volume{YourVolA}\ goto mount1
veracrypt /v \\?\Volume{YourVolB}\ YourOptionsB
goto end
:mount1
veracrypt /v \\?\Volume{YourVolA}\ YourOptionsA
:end
exit

Are you familiar with batch files? It's just a series of command lines in a plain text file, with .bat extension. Can provide a bit more info if needed.

If I were writing such a file, I'd make it a bit more complicated, to build in error checking, success messages etc, but the code snippet above would do the basic job.
