Task(s) cancelled due to the VCS failure

Post by acerot »

Task(s) cancelled due to the VCS failure. A couple of tasks scheduled to the same time. All using VSC. The first task runs ok. All the following are cancelled (see the picture). CobVSCRequester service logging on as the Local System account.

Is it intended to create (and delete after) VSC for each task separately even if there is a couple of tasks scheduled on the same time which all use VSC?

In the event log:

Code: Select all

Chyba služby Stínová kopie svazků: Při dotazu na rozhraní IVssWriterCallback došlo k neočekávané chybě. hr = 0x80070005, Přístup byl odepřen.

Addition: Trying to run manually a task which has the VSC usage ("Use Volume Shadow Copies") disabled in the task options. However, the task run is still being cancelled due to "...the creation of the VSC failed" (?)

The VSC is created when a task begins and deleted when the task ends. Then it is created for the next task (if needed), etc... This is done in order to save space in the disk. I will check this problem out.

I have just installed the 0.9.10 BETA version. I enabled "Cancel if Volume Shadow Copy fails" in the global settings. I enabled "Use Volume Shadow Copies" to a few of my tasks - and ran them all manually at the same moment. VSC was created and deleted around each task successfully. So, I am not sure what caused the improvement but now it worked flawlessly.
