CBT Error - Change tracking is disabled for the specified virtual hard disk,


#1

Upgraded PC’s to CBT client version 2.2.12 from 2.2.8.
My PC and Laptop are fine, Wife’s Windows 10 PC has the problem (was OK at 2.2.8).

CBT status shows CBT is active on C: with no crash persistence.

Email with the error I receive daily is below.

#2

Was it rebooted since installation?`

I guess the CBT status shows no messages? It actually should ^^


#3

Yes, it was rebooted.
Never saw messages before.
They are there now.

#4

It will probably show a better log message just after reboot. Currently it is crowded out by all those "… disabled … " messages.


#5

Did a reboot and this what status shows now:

C:

Volumes without change block tracking:

D:, E:

Last driver log messages:

#6

Ok, now it’s working again. Have another look once it stops working. Maybe with the next backup?


#7

OK, I will check.


#8

Looks like rebooting fixed it.
Thanks for the tip.
