Bitlocker To Go - AutoUnlock without Logging In

Bitlocker To Go - AutoUnlock without Logging In

I'm currently trying to resolve an issue with our offsite backup routine and hoping someone here can shed some light on my options.

We use 3 USB external disks on our main Windows 2012 file server which runs multiple batch scripts to copy backups etc to each of the USB disks over the course of the working day.
Each night one or more disks are taken off-site and can be used to restore to an off-site DR server in the event of a critical failure.

These drives are all BitLocker To Go encrypted and set to auto-unlock when connected to the server.
However it appears that they only unlock when someone is logged in on the server.

Reading up on this I cannot find the explanation for why this behaviour exists. In comparison my Windows 10 laptop automatically mounts a Bitlocker protected USB flash drive whether a user is logged in or not.

Am I missing something obvious here, or is this behaviour by design?

If auto-unlocking is unavailable in this scenario, I'd prefer to avoid scripting using manage-bde to unlock the drives. Is there a better alternative?

I should also note that this server has no TPM and fixed drives are not encrypted.



Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.
